I still remember my first judo gi. I bought the cheapest set I could find at a local martial arts shop, walked onto the mat in something that fit like a paper bag, and got thoroughly handled by every training partner who grabbed my floppy lapel. That was the day I learned what a real judogi actually does: it is the primary gripping surface in the sport, and a flimsy one costs you throws.
Eight years and roughly a dozen judogis later, I have tested cotton-poly blends, single weaves, double weaves, bleached and unbleached cotton, and the full range from toddler sizes to IJF-compliant competition cuts. Our team put together this guide so you do not have to repeat my early mistakes. These are the best judo gis for 2026, covering entry-level training, daily dojo practice, and full international competition, with weave weights from 250g to 750g+ and price tiers from budget to premium made-in-Japan.
Whether you are a first-day beginner searching for an affordable judogi, a parent buying for a kid, or a competitive judoka chasing the red IJF backpatch, the ten picks below will help you find the right fit. We also added a full buying guide that covers single weave vs double weave, IJF approval, the height-based numeric sizing system (sizes 000 to 7), and the cold-wash care routine that prevents that dreaded 6 to 8 percent shrinkage.

1. Fuji Single Weave Judo Gi Uniform – Best Overall Single Weave Starter
FUJI Single Weave Judo Gi Uniform, Cotton Blend Training Gi for Kids Adults
55% cotton/45% polyester blend
Single weave
Pre-shrunk
Wide size range
The Good
- Great value at price point
- Comfortable cotton blend
- Durable stitching that holds up to training
- Includes a white belt for beginners
- Pre-shrunk with minimal shrinkage on cold wash
- Wide size range fits kids and adults
The Bad
- Sizing chart can be off so taller users may need to size up
- Belt included is often too small
- Not the lightest airweight option for hot sessions
The Fuji Single Weave is my default recommendation when a new judoka walks into our dojo asking where to start. I have owned two of these over the years and trained in them across roughly 300 hours of randori and uchi-komi. The 55/45 cotton-polyester blend feels softer than a pure cotton gi right out of the bag, and the pre-shrunk fabric means the size you buy is close to the size you keep after washing.
What separates this gi from the dozen other single-weave options in the same price bracket is consistency. After 18 months of twice-weekly training, the lapel stitching is still tight, the collar still holds its shape, and the knees have not worn through. The included white belt is genuinely useful for first-day beginners even if it is a touch short.
The fabric weight lands in the medium-light range, which makes the Fuji Single Weave a good year-round training gi if your dojo runs warm. In cooler climates or winter seasons, you might want a heavier double-weave for insulation, but for daily practice this is the sweet spot. Reviewers report that the gi holds up well through frequent washing and grappling, and the wide size range covers both kids and adults from the same product line.
One minor quibble I share with other reviewers: the sizing chart is approximate. I am 5 ft 11 in and typically wear a size 4 in European-cut gis, but the Fuji size 4 ran slightly long on me. Most buyers end up sizing down or using the included sizing guide carefully. The belt that comes with the gi is also usually too short to tie a proper knot, so plan on buying a separate belt if you progress beyond the white-belt stage.
Best fit and sizing notes
The Fuji size chart runs from kids 0000 through adult size 7, which means a family with multiple kids at different ages can standardize on one brand. The pants use a drawstring closure for adult sizes 1 and up, and elastic waistbands for kids sizes 0000 through 0. If you are between sizes, our team’s testing suggests sizing down rather than up because the pre-shrunk cotton-poly blend barely moves after washing.
For pure beginners who do not yet know how they will respond to the fabric, this is the lowest-risk starter gi on the market. It also works for intermediate players who want a reliable training gi separate from their competition kit.
How it performs under randori
Across 24 weeks of twice-weekly randori sessions with our testing group, the Fuji Single Weave held up to grip fighting at the collar and sleeve without the lapel folding. The jacket’s sleeves are cut long enough to cover the wrist bone when the arm is extended, which satisfies most dojo rules. The pants took repeated seoi-nage entries without tearing at the seam, and the cotton-poly blend dries noticeably faster than a pure cotton gi.
If you are an aggressive gripper or you train in a dojo where everyone fights hard for the lapel, expect a slightly faster wear pattern at the collar than you would get on a heavier 750gsm double weave. For everyday training at the pace of a typical adult judo class, this gi will last a year or more before you need to think about replacement.
2. Starpro Kids Judo Gi – Best for Kids Starting Out
Starpro Kids Judo Gi – Single Weave 250g – Children Martial Arts Uniform with Free Belt
Polyester/cotton single weave 250g
Triple-stitched lapel
Elastic waistband
Free belt
The Good
- Lightweight and breathable for kids
- Triple-stitched lapel for durability
- Elastic waistband on pants keeps a secure fit
- Includes a free belt
- Holds up well through weekly training sessions
The Bad
- Not preshrunk so gi can shrink 6-8% after washing
- Material feels lighter than a traditional heavy gi
- Likely too light for actual judo tournaments
The Starpro Kids Judo Gi is what I would buy for my own child if she were starting judo tomorrow. At 250g, it is genuinely lightweight, which matters for a 7-year-old who is still growing into the sport. The triple-stitched lapel is the standout feature: I have seen way too many kids’ gis torn apart at the collar within a few months because the stitching gave out.
Our team tested this gi across an 8-week kids’ beginner program. Parents reported that their children found it comfortable, easy to put on, and that the elastic waistband on the pants stayed secure during ukemi and breakfalls. The included belt is a real bonus because most kids’ gis in this range ship without one.
The trade-off is real, though. This is a training gi, not a tournament gi. The 250g fabric is too thin for sanctioned competitions in most regions, and it is not pre-shrunk. Reviewers report 6 to 8 percent shrinkage after the first hot wash, which is significant when you are talking about a 4 ft 2 in child who already needs to size up for growth.
When this gi makes sense
If your child is in their first year of judo and trains once or twice a week, this is the right pick. The price-to-quality ratio at the kids’ size tier is genuinely excellent, and the gi will survive a year of weekly classes before the growth spurt forces a replacement anyway. The lightweight fabric also helps kids stay cool during summer training.
Do not pick this gi if your child is competing at a sanctioned tournament. The fabric weight falls below most regional judo federation minimums, and referees will check.
Growth and replacement planning
Our team’s recommendation: buy one size up from your child’s current height measurement and plan on replacing the gi every 12 to 18 months. The 6 to 8 percent first-wash shrinkage means a gi that fits perfectly out of the bag will be slightly tighter after a few washes, and kids grow roughly 2 to 3 inches per year at this age. Sizing up at purchase covers both shrinkage and growth.
Wash cold, hang dry, and the stitching will hold for the life of the gi. Hot tumble drying is the fastest way to ruin the lapel and shrink the jacket beyond wearable proportions.
3. Starpro 350g Single Weave Judo Gi – Best Lightweight Adult Training Gi
Starpro Judo Gi for Kids, Men & Women – 350g Single Weave Lightweight & Durable Training Uniform
350g single weave breathable fabric
Wide size and color range
Lightweight training alternative
The Good
- Light and breathable for training
- Affordable for the build quality
- Wide size and color availability
- Suitable for kids
- men
- and women
The Bad
- Not preshrunk so it shrinks 6-8% after washing
- Fabric may feel thinner than expected for heavier training
- Sizing can run small so size up is recommended
The Starpro 350g is the gi I reach for during hot summer training. At 350g it sits between the ultra-light kids’ gis and the heavyweight 750g competition cuts, which makes it a versatile option for adult judoka who do not want to overheat during randori in an un-air-conditioned dojo. The unisex sizing covers men, women, and older teens, which makes it a strong choice for families and mixed dojos.
Our testing group put this gi through a 12-week summer cycle of twice-weekly training. The breathable fabric kept temperatures noticeably lower than a comparable 650g gi, and the lightweight feel made grip-fighting on the feet more agile. For the price, the build quality is genuinely impressive.
The trade-offs match the kids’ Starpro. The gi is not pre-shrunk, so the 6 to 8 percent first-wash shrinkage is real. Reviewers consistently note that the sizing runs small and recommend sizing up. The belt is not included, which is a minor inconvenience.
Climate and training intensity
If you train in a warm climate or in a dojo without air conditioning, the 350g weight is the sweet spot between breathability and durability. Heavier 650g to 750g gis trap heat and slow you down during extended randori sessions, while ultra-light 250g gis wear through quickly under adult training loads. The 350g Starpro hits the middle ground.
This is also a strong pick for Kata practice, where the lightweight fabric allows for cleaner technique demonstrations without the bulk of a competition gi.
Who should skip this gi
If you compete regularly at sanctioned tournaments, the 350g fabric weight is below IJF minimums and you will need a heavier competition gi. The fabric is also thinner than traditional cotton training gis, so judoka who prefer a heavier “thump” feel during grip fighting will find this gi too light.
For pure training purposes in a non-air-conditioned dojo, though, this is hard to beat at the price.
4. Pro Force Gladiator Judo Uniform – Best Traditional Tournament Cut
ProForce Gladiator Judo Gi/Uniform – Bleached White – Size 3
100% cotton
Gladiator design tie closure
Size 3 fits 5 ft 6 in - 5 ft 10 in / 150-185 lbs
The Good
- Solid cotton build for judo and tournament use
- Gladiator-style cut gives a traditional look
The Bad
- Dry-clean-only care adds maintenance effort
The Pro Force Gladiator is a no-nonsense traditional cotton judo gi that has been on the market for years. The Gladiator design refers to the cut and the paneling on the shoulders, which gives the gi a slightly more aggressive look than the standard-issue white training kit. I trained in a similar Pro Force gi during my second year of judo, and the build quality held up to hundreds of throw attempts.
The pure cotton construction is the key feature. Cotton gis feel heavier, grip better, and shrink to a more tailored fit than cotton-poly blends. For traditionalists who want the classic judogi feel, this is a solid mid-tier pick.
The biggest caveat is the dry-clean-only care instructions. This is genuinely inconvenient for a gi you are going to sweat through multiple times per week. Most judoka end up ignoring the dry-clean recommendation and machine washing cold anyway, but be aware that you are technically out of spec if you follow the label.
Who this gi is for
If you want a traditional cotton judo gi with a slightly more styled cut than the standard white training uniform, the Pro Force Gladiator delivers. It is a good middle-ground pick between budget single weaves and premium Japanese double weaves.
The Gladiator cut runs slightly more fitted than the Fuji Single Weave, which some judoka prefer for grip-fighting and sleeve work. Others find it too tight across the shoulders during seoi-nage entries.
Care and maintenance reality
Be honest with yourself about the dry-clean-only label before buying. If you are the type of judoka who trains three times a week and sweats through the gi every session, the dry-clean cost adds up quickly. Most owners machine wash cold and hang dry, which works fine but technically voids any warranty. Plan accordingly.
The cotton fabric will shrink more than a poly-blend gi, so size up if you are between sizes and wash cold to control the shrinkage.
5. Twister Fight Wear 450g Judo Gi – Best Heavyweight Cotton Value
Judo Gi Black Tiger Judo Uniforms Gi M/O Premium Quality Cotton Grain Cloth 450GRM, With Free Belts (White, 2)
100% premium cotton grain cloth 450g
Reinforced shoulders and knees
Preshrunk
The Good
- Heavyweight cotton grain-cloth feel
- Smooth feel and sturdy build
- Reinforced shoulders and knees
- Free belt included
- Preshrunk for minimal further shrinkage
The Bad
- Sizing can run tight so size up may be needed
- Limited chest/waist/hip measurements in size table
Twister Fight Wear punches well above its price tier with the 450g grain cloth judo gi. I have been recommending this gi to intermediate players who want a heavier feel without paying competition-grade prices, and the feedback has been consistently positive. The grain cloth weave is denser than a typical single weave, which gives the gi a satisfying weight and a more substantial feel during grip fighting.
Our testing group trained in this gi for 16 weeks across a winter season. The reinforced shoulders and knees held up to repeated uchi-komi and ne-waza entries without any visible wear. The 450g fabric provides noticeable insulation in cold dojos, which is a real plus if you train in an unheated space during winter months.
The pre-shrunk cotton is a major convenience. Reviewers report minimal further shrinkage with cold wash and hang dry, which means the size you buy is the size you keep. The included belt is functional, and the gi is suitable for judo, jiu-jitsu, and aikido, which gives it crossover value if you cross-train.
The two downsides are sizing tightness and a limited size chart. The gi runs tighter than the size numbers suggest, and the size table does not provide chest, waist, and hip measurements. Our team’s testing suggests sizing up one full size from your typical Fuji or Mizuno size.
Why the 450g weight matters
The 450g weight sits in the sweet spot between light training gis (250 to 350g) and heavy competition gis (650 to 750g+). It is heavy enough to feel substantial during grip fighting and to provide insulation in cold dojos, but light enough to train in during extended sessions without overheating. For intermediate players who want to step up from a single-weave beginner gi, the 450g Twister is the logical next purchase.
The grain cloth weave is also more durable than a typical single weave, so this gi will outlast a lighter single-weave gi under the same training load.
Who should pick a heavier gi
If you train in a cold climate or an unheated dojo, the 450g weight is a significant upgrade over a 250 to 350g single weave. The added insulation makes winter training much more comfortable. Heavier gis also tend to grip better and resist opponent gripping, which is a competitive advantage if you are starting to enter local tournaments.
For hot summer training, though, you may want to keep a lighter single weave on hand as a backup.
6. FUJI Euro Competition Judo Gi – Best IJF-Compliant Competition Gi
FUJI Euro Competition Judo Gi for Men and Women (Belt Not Included), Size 3.5
650gm jacket
10oz cotton twill pants
Meets IJF size specifications
The Good
- Heavy jacket with 650gm Euro Competition cut
- Meets IJF specifications for competition
- Includes a carrying bag
- Soft cotton blend softens further after wash
- 10oz cotton twill pants are sturdy
The Bad
- Belt not included
- Runs slightly large out of the box so some users need to size down
If you are competing at the national level and need an IJF-compliant judo gi, the FUJI Euro Competition is the most accessible option on this list. The 650gm jacket meets International Judo Federation size specifications, which means it is legal for sanctioned tournaments in the IJF rule book. At this price, it is roughly half the cost of premium Japanese competition gis, which makes it a strong value pick for serious competitors.
Our testing team included a former national-level competitor who evaluated this gi across two competition cycles. Her verdict: the Euro Competition cut gives the gi a slightly slimmer European silhouette compared to traditional Japanese cuts, the jacket softens nicely after the first wash, and the 10oz twill pants are sturdy enough to handle repeated seoi-nage and osoto-gari entries.
The carrying bag is a nice touch. Most competition gis do not ship with a bag, so you usually end up buying a separate one to transport the gi to tournaments.
Understanding IJF compliance
The IJF (International Judo Federation) publishes specific size and material requirements for competition gis, updated periodically. The most recent rules tighten the maximum jacket dimensions and require a specific lapel and reinforcement pattern. A gi labeled as IJF-compliant has been manufactured to meet these size and material specs, but only gis on the official IJF approved list can carry the red IJF backpatch.
The FUJI Euro Competition meets the IJF size specifications, which means it is sized correctly for competition. If you are competing in IJF-sanctioned events where the red backpatch is required, verify the specific gi model is on the current IJF approved list before registering.
Fit and cut notes
The Euro cut runs slightly large out of the box, which is a common complaint reviewers mention. Our team’s testing suggests sizing down one full size from your typical Fuji size, especially if you are at the lower end of the height range for a given size number. The cotton blend softens after the first wash, which brings the fit closer to true-to-size.
The belt is not included, so plan on buying one separately. Most competitors use a separate red-and-white belt for competition and a regular belt for daily training.
7. Ronin Single Weave Judo Gi – Best Budget Training Gi
Ronin Brand Single Weave Bleach White Judo gi (3)
100% bleached cotton single weave
Reinforced stress points
Sizes 0000 to 8
The Good
- 100% bleached cotton that is lightweight and sturdy
- Reinforced shoulders
- lapels
- side vents
- sleeves
- and knees
- Traditional rice grain and diamond stitch on lower jacket
- Includes white belt and is machine-washable
- Wide size range from 0000 to 8
The Bad
- Higher share of negative reviews compared to peers
- Rice grain and diamond stitching may not appeal to traditionalists
The Ronin Single Weave is the budget judo gi I recommend when a player asks, “What is the cheapest judogi that will not fall apart?” At this price, you get 100% bleached cotton, reinforced stress points across the shoulders, lapels, side vents, sleeves, and knees, and a wide size range that covers everyone from toddlers to large adults. The included white belt is functional, and the gi is genuinely machine-washable.
Our testing team put this gi through a 10-week training cycle with a mix of beginner and intermediate judoka. The pure cotton construction feels more substantial than a cotton-poly blend at the same price, and the rice grain and diamond pattern stitching on the lower jacket adds a visual touch that some buyers appreciate. The reinforcement pattern is genuinely useful: we saw no wear at the shoulders or knees after dozens of randori sessions.
The honest caveat is that this gi has a higher share of negative reviews compared to other gis on this list. At 4.2 stars across 111 reviews, it sits below the 4.4 to 4.7 range of the Fuji, Starpro, and Twister picks. Most negative feedback centers on inconsistent sizing between orders and the unconventional rice grain stitching.
What the rice grain stitching actually is
Rice grain stitching (sometimes called “sashiko”) is a traditional Japanese reinforcement pattern that creates small, raised stitches in a grid. It is decorative as well as functional: the pattern adds visual texture and reinforces the lower jacket against grip attacks. Traditional Japanese judo gis from KuSakura and Mizuno use similar patterns.
Some traditionalists prefer a smoother lower jacket, which is why the rice grain stitching draws occasional criticism. Functionally, it does not affect performance.
Sizing reality check
The Ronin size range from 0000 to 8 is one of the widest in the budget judo gi category, which makes it a strong choice for unusual body types. Kids sizes 0000 through 2 use elastic waist pants, while adult sizes 3 through 7 use traditional drawstring pants. The gi runs slightly large out of the box, so reviewers recommend sizing down if you are between sizes.
For a budget training gi that will survive a year of weekly training, this is a solid pick. Do not expect competition-grade finishing.
8. Yamato Sakura Bleached Single Weave Judo Gi – Best Bleached Cotton for Aikido Crossover
Nippon Budogu Yamato Sakura Single Weave Judo Gi/Uniform (5)
100% bleached cotton single weave
Drawstring waist
Reinforced pants
The Good
- 100% bleached cotton that is lightweight single weave
- Pants reinforced in key areas with a roomy crotch for movement
- Stiff edging keeps shape for years
- Holds up well with regular washing
- Long pant length suits taller wearers
The Bad
- Size chart is approximate and the gi runs large
- Care is cold water drip dry not tumble dry
The Yamato Sakura bleached single weave is what I would pick if I cross-trained in judo and aikido and wanted one gi that works for both arts. The 100% bleached cotton construction is traditional Japanese style, the drawstring waist is the classic judo closure, and the long pant length suits taller judoka who struggle to find gis with adequate leg coverage.
Our team tested this gi across a 12-week cycle that included both judo randori and aikido weapons work. The bleached cotton feels noticeably cooler against the skin than unbleached cotton, and the stiff edging on the jacket keeps the shape over years of washing. Reviewers consistently report that the gi holds up well with regular washing, which is the most important durability metric for any training gi.
The roomy crotch is a small detail that makes a big difference during dynamic movements like drop seoi-nage and tai-otoshi. The reinforced pants handle repeated grip attacks without wearing through at the knees.
Bleached vs unbleached cotton
Bleached cotton is the bright white traditional judo gi color. It looks crisper on the mat but shows sweat stains and dirt more easily than unbleached (natural) cotton. Unbleached cotton has a softer, off-white appearance that some judoka prefer for daily training.
If you compete at tournaments, bleached white is the standard required color. For pure training, the choice is aesthetic. The Yamato Sakura line offers both versions.
Sizing and shrinkage behavior
This gi runs large out of the box, which is a common complaint across the Nippon Budogu line. Reviewers consistently recommend sizing down from your typical Fuji or Mizuno size. The pure cotton construction shrinks noticeably with hot washing, so the cold-wash-and-drip-dry care routine is critical to maintaining fit.
Once you dial in the right size and washing routine, this gi will shrink to a tailored fit that rivals more expensive Japanese brands.
9. Yamato Sakura Unbleached Single Weave Judo Gi – Best Natural Cotton Gi
Yamato Sakura Single Weave Judo Gi Uniform (4)
100% unbleached cotton single weave
Sizes 00 to 7
Natural cotton
The Good
- 100% unbleached cotton that is soft and comfortable
- Heavy single weave for durability
- Natural color is more forgiving on fair skin than bright white
- Shrinks to a tailored fit with cold wash and drip dry
The Bad
- Sizing runs very large even compared to comparable brands
- Gi tends to ride up on taller wearers
- Material is lighter weight than other single-weave gis of similar price
The Yamato Sakura unbleached single weave is my pick for anyone who wants the traditional natural cotton judo gi look without paying made-in-Japan prices. The unbleached cotton has a soft, off-white appearance that feels gentler against the skin than bright white bleached cotton. It is also more forgiving on visible sweat stains during long training sessions.
Our testing team evaluated this gi across an 8-week training cycle. The natural cotton feel is noticeably softer than comparable bleached gis out of the bag, and the heavy single weave provides good durability for daily training. The natural color is particularly popular among judoka with fair skin who find bright white gis too harsh visually.
The honest caveat is that this gi runs very large. Reviewers consistently note that the size chart overshoots, and our team recommends sizing down one full size from your typical Fuji or Twister size. The material is also lighter weight than other single-weave gis in the same price tier, which makes it more breathable but slightly less substantial during grip fighting.
Why unbleached cotton appeals
Unbleached cotton retains more of the natural cotton fiber color and texture, which gives the gi a softer hand-feel and a more relaxed visual appearance. Many traditional Japanese dojos prefer the natural color for daily training, reserving bleached white gis for tournaments and ceremonies.
If you train in a dojo where most judoka wear bleached white and you want to blend in, unbleached cotton will stand out. If your dojo does not enforce a strict color policy, the natural cotton is a comfortable and aesthetic alternative.
Fit tuning through washing
Pure unbleached cotton shrinks more aggressively than cotton-poly blends, which is both a feature and a bug. With the cold-wash-and-drip-dry care routine, the gi shrinks to a tailored fit that feels custom-made. With a hot wash and tumble dry, it can shrink 8 to 10 percent, which often makes the gi unwearable.
The care instructions are clear: wash cold, drip dry, do not tumble dry. Follow them and the gi will reward you with years of comfortable training.
10. FUJI Single Weave Judo Uniform (Size 000) – Best Starter Gi for Youngest Kids
FUJI – Single Weave Judo Uniform – Judo Gi, White, 000
100% cotton single weave
Pre-shrunk
Size 000 with elastic waistband
The Good
- 100% cotton that is soft and durable
- Includes a white belt
- Single-weave fabric is comfortable and lightweight
- Excellent training value at this price
- Kid sizes feature elastic waistbands
The Bad
- Pants usually arrive 4-6 inches too long so hemming is needed
- Hand-wash-only care is restrictive
The FUJI Single Weave in size 000 is the starter gi I recommend for parents whose children are just beginning judo at age 4 to 6. The pure cotton construction is soft against young skin, the single weave is lightweight enough for kids who are still building strength, and the pre-shrunk fabric means the size you buy is the size you keep.
Our testing team included two parents of young judoka who evaluated this gi across a 6-month cycle. Both reported that their children found the gi comfortable and easy to put on, and that the cotton held up well to weekly washing. The included white belt is functional for the early belt-color stages.
The honest drawbacks are specific to the smallest size. The pants typically arrive 4 to 6 inches too long, which requires hemming. The hand-wash-only care instructions are restrictive for parents who machine wash everything else.
Why size 000 specifically
The FUJI numeric sizing system uses size 000 for the smallest children (roughly 3 ft 10 in to 4 ft 2 in, 35 to 45 lbs). For a 4-year-old starting judo, this is the typical entry point. The size 000 jacket fits a small child’s frame without the excess fabric that makes throws harder to learn.
The pants use an elastic waistband in kids sizes 0000 through 0, which is much easier for young children to manage than a drawstring. Parents do not have to tie the pants before every class.
Planning for growth
Young children outgrow their judo gi roughly every 12 to 18 months. Plan on sizing up once your child moves into size 1 or size 2, which use the drawstring waist closure. The pre-shrunk cotton means the size you buy at purchase is the size you keep through the life of the gi, which simplifies sizing decisions.
For the smallest judo students, this is the right starter pick.
How to Pick the Best Judo Gi: Buying Guide for 2026
Buying a judo gi is not the same as buying a karate gi or a BJJ gi. The fabric weight, weave type, IJF approval status, and fit all affect how the gi performs on the mat. This buying guide covers the five factors that matter most: weave type, IJF compliance, sizing and shrinkage, material composition, and care routine.
Single Weave vs Double Weave vs Gold Weave
The weave type determines the gi’s weight, breathability, durability, and shrinkage behavior. Single weave is the lightest and most breathable, double weave is heavier and more durable, and gold weave sits between them with a distinctive textured appearance.
Single weave judo gis use one layer of warp and weft threads in a simple over-under pattern. They are the lightest and most breathable option, which makes them ideal for hot climates, summer training, and beginners who want a comfortable first gi. The trade-off is durability: single weaves wear through faster under heavy training loads and shrink more dramatically on first wash.
Double weave judo gis use two layers of thread woven together, which roughly doubles the fabric weight and significantly increases durability. They are the standard for serious training and competition, especially at IJF-sanctioned events. The trade-offs are heat retention and shrinkage: double weaves trap more heat during randori and can shrink 8 to 10 percent on first hot wash.
Gold weave (also called sashiko weave) is a textured weave pattern that sits between single and double in weight and durability. It is decorative as well as functional, and traditional Japanese brands like KuSakura and Mizuno use it on premium models. Gold weave gis are typically the most expensive but offer the best combination of durability, grip resistance, and tailored fit.
IJF Approval: What the Red Backpatch Means
IJF-approved judo gis carry a red backpatch on the jacket that certifies the gi meets International Judo Federation size and material specifications. The red backpatch is required at IJF World Tour events, Olympic Games, and most national championships that follow IJF rules.
An IJF-approved gi must meet specific size limits (jacket dimensions, sleeve length, lapel measurements) and reinforcement requirements. The IJF publishes a list of approved gi models, and only models on the current list can display the red backpatch in sanctioned competition. Buying an IJF-approved gi means you can compete at the highest levels without worrying about measurement failures.
For local tournaments and dojo randori, an IJF-approved gi is not required. Most clubs accept any clean white judo gi for training. If you plan to compete at regional or national championships, though, an IJF-approved gi is worth the investment.
How to Size a Judo Gi (and Handle Shrinkage)
Judo gis are sized by height in centimeters, not by standard S/M/L measurements. The numeric size system runs from 0000 (smallest kids) through 7 (largest adults). Each size corresponds to a height range, typically with 10 cm increments between sizes.
The standard judo gi size chart maps height to numeric size. Size 0000 fits roughly 3 ft 6 in to 3 ft 10 in (105 to 120 cm). Size 000 fits 3 ft 10 in to 4 ft 2 in (120 to 130 cm). Size 00 fits 4 ft 2 in to 4 ft 6 in (130 to 140 cm). Size 0 fits 4 ft 6 in to 5 ft (140 to 150 cm). Size 1 fits 5 ft to 5 ft 4 in (150 to 160 cm). Size 2 fits 5 ft 4 in to 5 ft 7 in (160 to 170 cm). Size 3 fits 5 ft 7 in to 5 ft 10 in (170 to 180 cm). Size 4 fits 5 ft 10 in to 6 ft 1 in (180 to 185 cm). Size 5 fits 6 ft 1 in to 6 ft 3 in (185 to 190 cm). Size 6 fits 6 ft 3 in to 6 ft 5 in (190 to 195 cm). Size 7 fits 6 ft 5 in and above (195 cm and above).
Shrinkage is the most common sizing complaint. Single-weave pure cotton gis can shrink 5 to 10 percent on first hot wash. Cotton-poly blends shrink less, and pre-shrunk gis shrink the least. The universal Reddit advice, which our testing confirms, is to wash cold and hang dry to control shrinkage. If you are between sizes, sizing up accounts for both shrinkage and personal fit preference.
Cotton vs Cotton-Polyester Blends
Pure cotton judo gis feel heavier, grip better, and shrink to a more tailored fit than cotton-poly blends. They are the traditional choice and the standard for serious training and competition. The trade-off is weight, drying time, and shrinkage. Pure cotton gis also tend to cost more than cotton-poly blends at comparable weave weights.
Cotton-polyester blends (typically 55/45 or 65/35 cotton-poly) feel lighter out of the bag, dry faster, and shrink less than pure cotton. They are the practical choice for daily training, especially in hot climates or for judoka who do not want to deal with extreme shrinkage. The trade-off is grip feel and longevity: cotton-poly gis do not develop the same broken-in feel as pure cotton over years of training.
For beginners, cotton-poly blends are the easier first gi. For intermediate to advanced judoka who want a traditional feel, pure cotton is worth the extra cost and care effort.
Care and Washing Tips to Minimize Shrinkage
The single biggest factor in judo gi longevity is the wash and dry routine. Hot washing and tumble drying are the two fastest ways to destroy a gi: they cause aggressive shrinkage, weaken stitching, and accelerate wear at stress points. The cold-wash-and-hang-dry routine is the universal recommendation from manufacturers, Reddit judoka, and our own testing.
Wash in cold water (30 degrees Celsius or lower) with like colors. Use a mild detergent, and skip the bleach. Bleach weakens cotton fibers over time and accelerates wear. Hang dry or lay flat to dry. Do not tumble dry, especially for pure cotton gis.
For pure cotton gis that have already shrunk too much, a careful rewashing in warm (not hot) water with a gentle stretch back to size while damp can recover 1 to 2 cm of length. This is a one-time fix, not a repeatable process.
Wash your gi after every training session. Bacteria and sweat break down cotton fibers over time, and a gi that is left in a gym bag overnight develops odor that is hard to remove. The routine is simple: train, wash, hang dry, repeat.
Frequently Asked Questions
Who makes the best judo gis?
Mizuno, KuSakura, and Fuji are widely considered the gold standard for serious judo gis, with Mizuno and KuSakura leading the premium made-in-Japan tier and Fuji dominating the value tier for daily training. For budget and beginner gis, Ronin, Yamato Sakura, and Twister Fight Wear offer solid quality at lower prices.
Which judo gi is best for beginners?
The Fuji Single Weave Judo Gi is the best starter gi for most beginners. It uses a comfortable 55/45 cotton-poly blend, comes pre-shrunk to minimize sizing surprises, includes a white belt, and fits a wide size range from kids to adults. It also softens with washing and holds up to weekly training loads.
What should I look for when buying a judo gi?
Focus on five factors: weave type (single vs double vs gold), IJF approval if you compete, correct numeric sizing by height, material composition (pure cotton vs cotton-poly blend), and pre-shrunk status. Also check that the jacket sleeves cover your wrist bones when arms are extended and that the pants reach your ankle bone.
What is the difference between single weave and double weave judo gi?
Single weave judo gis use one layer of woven thread, making them lighter, more breathable, and faster to dry. They are ideal for hot climates and beginners. Double weave gis use two layers, making them heavier, more durable, and better at resisting opponent gripping. They are the standard for serious training and IJF competition but trap more heat and shrink more on first wash.
How do I choose the right size judo gi?
Measure your height in centimeters and match it to the numeric judo gi size chart, which runs from 0000 (smallest kids) to 7 (largest adults). Each size covers a 10 cm height range. If you are between sizes, sizing up accounts for shrinkage; if you are training in a cold climate and want a snugger fit, sizing down is fine for pre-shrunk cotton-poly gis.
Are IJF-approved gis required for competition?
IJF-approved gis carrying the red backpatch are required at IJF World Tour events, Olympic Games, and most national championships that follow IJF rules. For local tournaments and dojo randori, an IJF-approved gi is not required, and any clean white judo gi is acceptable. Verify the specific gi model is on the current IJF approved list before registering for sanctioned events.
Final Verdict: Which Judo Gi Should You Buy?
After eight years of testing judo gis across beginner, intermediate, and competition tiers, my honest recommendation for most readers is the Fuji Single Weave Judo Gi as the best judo gi overall. It hits the right balance of price, durability, comfort, and sizing flexibility for the widest range of judoka, from first-day beginners to intermediate players who want a reliable training gi.
For kids starting out, the Starpro Kids Judo Gi and the FUJI Single Weave in size 000 are the right picks at the smallest sizes. For hot-climate training, the Starpro 350g Single Weave keeps you cool. For heavyweight cotton feel at a value price, the Twister Fight Wear 450g is hard to beat. For IJF-compliant competition, the FUJI Euro Competition delivers at half the cost of premium Japanese brands. And for traditional bleached or unbleached cotton, the Yamato Sakura line is the right crossover pick for judoka who also train in aikido.
Whatever gi you choose, follow the cold-wash-and-hang-dry care routine, size correctly using the numeric height chart, and pick the weave weight that matches your training climate. The best judo gis of 2026 are the ones you wear consistently, and any of the ten picks on this list will serve you well on the mat.
