How to Choose No-Gi Gear for Training
A practical guide to choosing your first no-gi BJJ kit, including rash guards, grappling shorts, spats, sizing, competition rules, and when to buy more than one set.
No-gi gear is easier to pack than a gi, but it is not automatically easier to buy. A normal gym shirt can ride up, loose shorts can catch fingers and toes, and a rash guard that feels fine standing still can feel wrong after ten rounds. Use this guide to build a practical no-gi training kit without overbuying. The goal is simple: choose gear that stays in place, protects training partners, fits your gym's expectations, and gives you enough clean rotation to keep training.

The Short Answer
For regular no-gi BJJ training, start with a fitted rash guard and grappling shorts. Add spats or compression shorts if you want more skin coverage, if your gym prefers them, or if you are building a larger weekly rotation. Do not start with five matching kits before you know what sleeve length, short length, waistband, and compression feel you actually like.
If you are buying for competition, start with the rules before the brand. IBJJF no-gi rules require a skin-tight elastic shirt long enough to cover the torso to the shorts waistband. The rules also control shirt color and rank-color use, shorts colors, pockets, exposed drawstrings, buttons, zippers, risky plastic or metal pieces, and shorts length. Training gear and tournament gear can overlap, but they are not always the same decision.
What You Need First
Item | Buy it when | Check before ordering |
|---|---|---|
Rash guard | Always. This is the core no-gi top for most BJJ rooms. | Compression, torso length, sleeve length, seams, size chart, and whether it rides up. |
Grappling shorts | Almost always. They are safer and more useful than normal gym shorts. | No pockets or safe stitched pockets, no exposed hardware, good hip mobility, and secure waistband. |
Spats | Optional for extra coverage, cold gyms, mat-burn reduction, or personal preference. | Waistband security, transparency under stretch, length, and whether your gym wants shorts over them. |
Compression shorts | Useful under grappling shorts if you want a tighter base layer. | Comfort, coverage, waistband, and whether they stay put during wrestling and guard work. |
Extra sets | After you know the first kit works. | How often you train, how fast laundry dries, and whether the same size fits across brands. |
Choose the Rash Guard First
The rash guard is the item you will notice most during training. It should fit close to the body without cutting off movement or breathing. If it is too loose, it can twist, bunch, and get grabbed. If it is too tight, you will avoid wearing it.
Look for enough torso length to stay down during shots, inversions, scrambles, and guard retention. Gold BJJ's Foundation rash guard page is a useful example of the kind of fit detail to look for: it says its rash guards are designed to fit tight, tells buyers to size up for a looser fit, and highlights an extended cut, flatlock stitching, mesh armpit vents, and sublimated graphics.
Sanabul's Core compression rash guard is another practical example. The official product page frames it for MMA, grappling, and no-gi BJJ, lists small through XXL sizing, and points to four-way stretch polyester fabric, ventilated underarm panels, and sublimated graphics. You do not need that exact product, but you should look for that level of product-page clarity before buying.
Pick Shorts That Are Built for Grappling
Good no-gi shorts should let you wrestle, squat, pass, invert, and play guard without pulling, catching, or exposing hardware. The biggest mistake is buying normal gym shorts because they look close enough. Pockets, zippers, buttons, dangling drawstrings, and loose parts can create problems for you and your training partners.
For class, ask whether your academy has specific rules. Some gyms are relaxed. Others do not want pockets or metal hardware on the mat. For competition, be stricter. IBJJF rules require men's board shorts to avoid unsafe hardware and sit from at least halfway down the thigh to no longer than the knee. Women's no-gi bottom rules allow shorts, compression shorts, and skin-tight spats in specified colors, with similar pocket, hardware, and length controls for shorts.
If you want a simple shopping path, start with BJJ or grappling-specific short categories rather than general fitness shorts. Brands such as Gold BJJ, Progress Jiu-Jitsu, Scramble, and Hyperfly all give clear no-gi short or shorts-and-spats category paths.
Decide Whether You Need Spats
Spats are optional for most beginners, but they can be useful. They add skin coverage, reduce direct mat contact, and give you a tighter base layer under shorts. Some athletes like them for leg entanglements and wrestling-heavy rounds because there is less loose fabric.
The tradeoff is heat and compression. Some people feel better with full leg coverage; others overheat or feel restricted. If you are unsure, buy the rash guard and shorts first, then add spats once you know your training room, laundry rhythm, and comfort preference.
If you plan to compete, check the ruleset. Do not assume every event treats spats, compression pants, compression shorts, and board shorts the same way.
Use Product-Specific Size Charts
No-gi sizing is not the same as gi sizing. Your A2 gi does not tell you whether you need a medium rash guard, large shorts, or 32-inch grappling shorts. Compression tops, shorts, and spats all fit different parts of the body.
Tatami's official size guide is a good reminder: it separates men's, ladies, and kids no-gi/leisurewear guides and says the guide is approximate because garment sizes may vary by supplier. That caveat matters across the whole category. Even inside one brand, a rash guard, shorts, and spats may not all behave the same way.
Use your weight, chest, waist, height, and fit preference together. If a rash guard brand says the product is designed to fit tight, decide whether you actually want that. If a shorts page uses waist sizes, do not order based only on your normal casual short size unless the chart supports it.
Competition Rules Change the Purchase
For regular training, fit and safety usually matter more than rank-color details. For competition, rules can decide the purchase before style does. IBJJF no-gi rules require the top to be elastic, skin-tight, long enough to cover the torso to the waistband, and colored black, white, black-and-white, or with rank-color requirements. Shirts that are fully the athlete's rank color are also permitted under the official language.
Shorts have their own checks. Men's board shorts must avoid unsafe pockets and exposed hardware, and the length has to be within the allowed range. Women's no-gi bottoms can include shorts, compression shorts, and skin-tight spats in approved colors, but shorts still have pocket, hardware, and length requirements.
A competition-labeled collection can help you start in the right place. Progress Jiu-Jitsu, for example, has an official IBJJF Legal No Gi collection with rashguard and shorts filters. Still, check the exact item, color, size, event rules, and inspection process before relying on any product for tournament day. For a broader rules checklist, use the IBJJF uniform rules guide before you compete.
How Many Sets Should You Buy?
If you train no-gi once per week, one rash guard and one pair of grappling shorts can work, but two tops is more comfortable because laundry mistakes happen. If you train no-gi two or three times per week, build toward at least two or three rash guards and two pairs of shorts. Add spats or compression shorts if you like the coverage.
Buy the first kit carefully, then repeat only after you have trained in it. This matters more than matching. A rash guard that stays down and shorts that move well are worth duplicating. A kit that only looks good in a product photo should not become a full rotation.
Where to Start by Buyer Type
If you want the simplest training setup: compare practical rash guard and shorts options from Sanabul Sports, Gold BJJ, or Tatami Fightwear. Look for clear sizing, easy replacement, and enough basic colors that you can build a rotation.
If competition is the reason you are buying: start with the rules, then compare competition-focused paths such as Progress Jiu-Jitsu or ranked rash guard options from brands that publish clear product-level claims. Do not buy by brand name alone.
If design matters: add Scramble and Hyperfly to the shortlist. Both have no-gi category paths with rash guards and shorts, and both make more sense once you know your preferred fit.
If you train both gi and no-gi: you can stay with one brand if the sizing works across categories, but do not force it. A gi size does not guarantee a rash guard or shorts fit.

Common Buying Mistakes
Buying only for design: a great graphic does not fix a short torso, scratchy seams, or shorts that restrict your hips.
Ignoring the waistband: shorts that slide, twist, or loosen during rounds become distracting fast.
Assuming gym clothes are enough: normal shorts and shirts may be fine for lifting, but grappling creates different safety and durability problems.
Overbuying before testing fit: buy one kit, train in it, then build the rotation.
Using training gear for competition without checking rules: color, rank markings, pockets, hardware, and length can all matter.
FAQ
Can I wear a normal T-shirt for no-gi BJJ?
Some gyms may allow it for a first trial class, but a fitted rash guard is better for regular training. It stays closer to the body, reduces loose fabric, and is built for sweaty grappling rounds.
Do I need long sleeve or short sleeve rash guards?
Both can work for training. Long sleeves give more skin coverage. Short sleeves usually feel cooler and less restrictive. If you compete, verify the current ruleset before assuming either sleeve style is acceptable.
Should no-gi shorts have pockets?
For BJJ, avoid open pockets and unsafe hardware. IBJJF rules require men's board shorts to have no pockets or fully stitched-shut pockets, with no buttons, exposed drawstrings, zippers, or risky plastic or metal pieces. Even for normal class, pocket-free grappling shorts are the safer default.
Are spats required for no-gi?
Usually no. Spats are a preference item unless your gym or event requires a specific bottom layer. They are useful for skin coverage and compression, but many beginners can start with rash guard and grappling shorts first.
How tight should a rash guard be?
It should be close enough that it does not flap, twist, or ride up, but not so tight that breathing, shoulder movement, or posture feels restricted. Check each brand's size chart and size-up notes rather than relying on your normal T-shirt size.
How much no-gi gear does a beginner need?
Start with one rash guard and one pair of grappling shorts if you train no-gi occasionally. If no-gi is part of your weekly routine, two rash guards and two shorts are a more practical minimum. Add more only after the first kit proves it fits.
Final Thought
The best no-gi kit is not the loudest kit or the most expensive kit. It is the kit that lets you train without thinking about your clothes. Start with a rash guard that stays down, shorts that move safely, and sizing you can repeat.
Once your first kit works, then buy more. That is the cleanest way to avoid a drawer full of rash guards that look good but never make it into your gym bag.
