So you've decided to try no gi Brazilian Jiu Jitsu. Brilliant choice. But before you step on the mats for the first time, there's one question almost every beginner asks: what do I actually wear?
No gi BJJ doesn't use the traditional kimono (the gi), so the kit is different from what you might have seen in judo or gi jiu jitsu. The good news is it's simple, affordable, and you probably only need two things to get started. Here's everything you need to know, whether you're kitting out yourself or your kids.
What is no gi BJJ?
No gi Brazilian Jiu Jitsu is grappling without the traditional gi jacket and belt. Instead of gripping the fabric of a kimono, you work with body control, underhooks and hooks. Because there's no jacket to grab, you wear close-fitting athletic gear that won't get in the way and won't give your training partner anything loose to catch hold of.
That's the key principle behind no gi clothing: fitted, flexible and secure. Let's break down exactly what that means.
What to wear for no gi BJJ
1. A rash guard
A rash guard is the single most important piece of no gi kit. It's a tight-fitting, stretchy top, usually short or long sleeved, made from a quick-drying technical fabric. It does several jobs at once: it protects your skin from mat burn, keeps your training partners safe from your sweat, and gives nothing loose for an opponent to grab.
For your first class, a short-sleeve rash guard is a great all-rounder. Look for one that's sublimation printed (so the design won't peel or crack), comfortable through the shoulders, and snug without being restrictive. Our Viper no gi rash guard is built exactly for this, and you can see the full range on our BJJ rash guards page.
2. Grappling shorts (or spats)
On the bottom half you've got two options. The most popular is a pair of no gi grappling shorts: lightweight, flexible board shorts with a secure waistband and no zips or pockets to catch fingers and toes. A 4-way stretch fabric is ideal because it moves with you through every scramble. The Viper board shorts are a solid first pair and match the rash guard for a clean set.
The other option is spats: tight, full-length leggings worn for extra coverage and skin protection. Many grapplers wear shorts over the top of spats. You can mix and match once you know what you prefer, but for a first class, a good pair of shorts is all you need.
3. What to wear underneath
Men typically wear compression shorts or underwear under their grappling shorts. Women usually wear a sports bra under the rash guard, and often spats or shorts on the bottom. The aim is comfort and coverage so you can focus on learning, not adjusting your kit.
What NOT to wear to no gi BJJ
Just as important as what to wear is what to leave at home:
- Loose t-shirts and baggy shorts — they ride up, get grabbed, and get in the way.
- Anything with zips, buttons or pockets — these can catch fingers and toes and cause injury.
- Jewellery — rings, necklaces and earrings should always come off before rolling.
- Clothing made from heavy cotton — it soaks up sweat, gets heavy, and dries slowly.
Your first no gi class kit checklist
Keep it simple. Here's everything a beginner needs:
- A fitted rash guard (short sleeve is fine to start)
- Grappling shorts or spats
- Compression layer or sports bra underneath
- Flip flops or sliders for walking to and from the mat
- A water bottle and a towel
- A mouthguard (recommended once you start live rolling)
Kids and no gi BJJ
Kids need exactly the same basics as adults, just sized for them: a fitted rash guard and a pair of flexible shorts. Comfortable, secure kit helps young grapplers feel confident and stay focused in class. Our Kids Viper rash guard and Kids Viper shorts come in youth sizes for ages 5 to 13, and there's more in our kids no gi range. A matching set is also a nice confidence boost for a nervous first-timer.
Staying fresh: a quick word on hygiene
BJJ is a close-contact sport, so hygiene matters from day one. Always train in clean kit, wash your rash guard and shorts after every session (cold wash, hang dry), keep your nails short, and shower as soon as you can after class. It keeps you and your training partners healthy, and it's simply good mat etiquette.
Ready to roll
That's it. A rash guard, a pair of shorts, and you're ready for your first no gi class. Keep it fitted, keep it simple, and focus on enjoying the learning. If you want to look the part while you're at it, check out the Viper from our new Neon Warfare range, available as a matching rash guard and shorts set for both adults and kids.
Frequently asked questions
Do I need a rash guard for no gi BJJ?
Yes. A rash guard protects your skin, manages sweat and is standard kit for no gi training. It's the one item you really shouldn't skip.
Can I just wear a normal t-shirt and shorts?
It's best not to. Loose clothing rides up, gets grabbed and can be a hazard. Fitted grappling gear is safer, more comfortable and keeps you focused on training.
Should I wear shorts or spats?
Either works. Shorts are the most common choice for beginners. Spats add coverage and skin protection, and many grapplers wear shorts over them. Start with shorts and experiment later.
What should my child wear to their first no gi class?
The same as adults, in youth sizing: a fitted rash guard and flexible shorts. Comfortable, secure kit helps kids feel confident on the mats.
