What to Wear to Jiu Jitsu: Gi, No-Gi & First Class Guide
Written by BJJ Academy Finder Editorial Team
You've signed up for a class, or maybe your child has, and now the most immediate question kicks in: what do you wear to jiu jitsu?
That small question makes a lot of people more nervous than the training itself. You don't want to show up underdressed, overdressed, or wearing something that makes you stand out for the wrong reason. A lot of first-timers sit in their car before class wondering if regular gym clothes are fine, whether they need a gi on day one, or if they're about to break some unwritten rule.
The good news is that this is one of the easiest beginner problems to solve. Jiu jitsu clothing follows a few practical rules, and once you understand the reason behind them, the whole thing becomes much less confusing. You don't need to know every brand, buy a closet full of gear, or look like a seasoned competitor to start training well.

Stepping on the Mat for the First Time
A common first-class scene looks like this. You've got a water bottle in one hand, your phone in the other, and three outfits spread across the bed. One is too loose. One looks too casual. One seems like it might work, but you're not sure if it's “jiu jitsu enough.”
That uncertainty is normal. Most beginners care less about looking stylish and more about avoiding embarrassment. They want to know if they can walk in, train safely, and not discover halfway through class that their shorts have pockets, their shirt keeps riding up, or everyone else is dressed completely differently.
If that sounds familiar, you're not overthinking it. You're just trying to be respectful and prepared. That's a good instinct, and it's part of why many people start by reading beginner resources like this guide on jiu jitsu classes for beginners before they ever step on the mat.
Most gyms expect beginners to have questions. Clothing is one of the first ones instructors hear.
The main thing to know is that Brazilian jiu jitsu usually falls into two clothing systems. There's gi, which uses the traditional uniform, and no-gi, which uses fitted athletic gear. Once you know which class you're taking, the rest gets much easier.
Understanding the BJJ Dress Code Gi vs No-Gi
Your first clothing decision is simple. Find out whether your class is gi or no-gi.
That one detail answers almost every other question. It tells you what to wear, what kinds of grips people will use, and why one class may feel slower and more grip-heavy while another feels faster and more slippery.
Why the gi exists
A gi is the traditional uniform: jacket, pants, and belt.
The reason for it is practical, not just historical. The jacket and pants give both training partners fabric to grip, which changes how positions work. Sleeves, collars, lapels, and pant legs all become part of the skill set. If someone grabs your collar, they can slow you down, break your posture, or set up a choke. If they control your sleeve, escaping gets harder.
Gi training works like grappling with built-in handles. That is why the uniform matters so much.
It also creates a more standardized training environment. Thick fabric covers more skin, holds up to repeated gripping, and helps classes run with fewer clothing problems than a loose T-shirt and gym shorts would. If you decide to buy one later, this guide to choosing a BJJ gi for beginners can help with sizing and starter options.
For a first class, though, you may not need to own a gi yet. Many gyms lend one to beginners or let you try a class before buying anything. That lowers the cost of getting started, which is helpful because you do not need to invest much before you know you enjoy training.
Why no-gi clothing looks different
No-gi replaces the jacket and pants with fitted athletic clothing. The usual setup is a rash guard on top and grappling shorts, compression shorts, leggings, or spats on the bottom.
The close fit has a clear purpose. Loose fabric bunches up, rides over the face, catches fingers and toes, and creates accidental grips that do not belong in no-gi training. Fitted gear stays put and makes movement safer and more predictable.
That is also why gyms often tell beginners to avoid regular basketball shorts, shirts with big sleeves, or anything with pockets, zippers, buttons, or metal pieces. Those details seem minor until someone's finger gets caught or the mat gets scratched.
If your hands are getting scraped up as you train more often, Evermost LLC's guide to hand taping is a useful next step, but most first-timers can keep things simple and focus on wearing clean, snug clothing.
First class vs long-term gear
This is the part beginners are often relieved to hear. Your first class and your future setup do not have to look the same.
If your gym says the class is no-gi, a clean fitted workout shirt and pocket-free athletic shorts are often enough for day one. If the class is gi, many gyms will loan you a uniform or tell you exactly what to bring. Starting with basic gym clothes, if the academy allows it, is completely normal.
Long term, you will probably want clothing made for grappling because it fits better, lasts longer, and causes fewer problems during training. But that comes later. The first goal is to show up in the right type of clothing for the class, train safely, and avoid obvious issues like loose fabric or sharp hardware.
How to tell which class you're attending
Do not guess from photos on a gym's website. Check the schedule or send a quick message.
Some academies run gi classes on certain days and no-gi on others. Some label beginner classes clearly. Some call a class “fundamentals” and expect students to know the dress code already. Asking ahead saves you from showing up in a gi to a no-gi class, or vice versa.
A simple message works: “Hi, I'm coming to my first class. Is it gi or no-gi, and what should I wear?”
That question makes a good first impression because it shows you care about safety, hygiene, and following the room.
Beyond the Uniform Essential Protective Gear
The uniform gets you onto the mat. The smaller gear choices help you train without constant little problems.
A good rule is simple. If something can snag, shift, scratch, or distract you, it probably does not belong in class. Jiu jitsu has a lot of twisting, posting, and close body contact, so gear works best when it stays close to the body and does not create extra friction for you or your partner.
For a first class, you do not need a pile of extras. Bring only what helps with comfort and safety. If you keep training, you can add the pieces that solve problems you run into, which is usually a better approach than buying everything at once.
The pieces that help most
A few items come up again and again because beginners notice the benefit right away.
Rash guard
A rash guard works like a fitted base layer. It keeps loose fabric out of the way, adds coverage during scrambles, and makes training feel less abrasive under a gi. In no-gi, it also helps your shirt stay put instead of bunching around your shoulders. If you want ideas after a few weeks of training, this guide to the best rash guards for BJJ can help you compare options.Compression shorts or spats
These solve a very practical problem. Regular shorts shift. Compression layers stay put when you bridge, sprawl, invert, or end up folded into awkward positions. Many people wear them under shorts in no-gi or under gi pants for extra coverage.Mouthguard
Jiu jitsu is not a striking class, but accidental contact happens all the time. A shot can come up higher than expected. A partner can bump your chin during a scramble. A mouthguard is a small item that can save you from a chipped tooth or a sore jaw.Optional support gear
Some students use a soft knee sleeve, light ankle support, or athletic tape if a joint is already irritated. That is not a day-one requirement. It is more of a long-term adjustment once you learn how your body responds to training.
What usually causes problems
Beginners often ask what gear to avoid. The easiest test is to look for anything hard, loose, or grabby.
- Shorts with pockets can trap fingers and toes
- Zippers or buttons can scratch training partners and damage mats
- Jewelry can catch, bend, or tear skin
- Loose shirts or baggy tops ride up and become a distraction
- Bulky hair clips or hard accessories press into you or your partner during rolls
If you are unsure, do a quick movement check at home. Squat, sprawl, raise your arms, and turn side to side. If the item slides around or feels like it could catch on something, choose a simpler option.
This short video gives a helpful visual sense of protective gear basics and what beginners tend to overlook.
Small extras that make training easier
You do not need to show up looking like a sponsored athlete. You just want fewer distractions.
If your fingers get sore from gripping, especially in gi classes, basic taping can help support the joints and protect irritated skin. Evermost LLC's guide to hand taping gives a clear starting point without making it feel complicated.
Long hair should be tied back securely and kept low-profile. Simple is better. The less you have to adjust during class, the more attention you can give to learning.
Mat Etiquette Hygiene and Safety Essentials
A clean uniform isn't about appearances. It's about trust.
Jiu jitsu puts people in very close contact. Faces get near shoulders. Hands slide across sleeves, arms, and mats. When someone shows up in fresh gear and with basic grooming handled, training feels safer immediately. When they don't, everyone notices.
Clean gear is part of training
Wear clean gear every session. Not “still smells okay.” Clean. If you trained in it already and it's sweaty, wash it before wearing it again.
The same goes for your body. Shower if you're coming from work, another workout, or a long day out. If you have cuts, cover them. If you have a skin issue, sit out and ask the coach what the gym expects.
Training clean is one of the fastest ways to show respect in a jiu jitsu room.
A lot of beginners think hygiene is a side issue compared with technique. It isn't. It's part of being a good training partner.
The small habits people notice
Some etiquette rules are so normal inside gyms that nobody explains them until a beginner accidentally breaks one. These are easy to get right:
- Trim fingernails and toenails so you don't scratch partners during scrambles.
- Wear sandals or slides off the mat so you're not walking barefoot into bathrooms and then back onto the training area.
- Ask about academy rules if you're unsure whether they want a shirt under the gi or specific uniform colors.
- Put your gear on in the changing room if the academy expects that, especially for kids programs and family classes.
A family bringing a child to class should think of this the same way they would any close-contact sport. The uniform matters, but the habit of keeping it clean matters just as much.
Kids often learn these routines fast when adults make them part of the pre-class ritual: clean gear, clipped nails, sandals, water bottle.
Dressing for Your Role Beginners Kids and Competitors
The right outfit depends partly on who you are and why you're training. A trial-class adult, a parent buying for a child, and a competitor getting ready for a ruleset don't need the same advice.
If you're a beginner
Many individuals encounter a common misconception. They assume they need specialized gear before they're “allowed” to start.
Usually, they don't.
Multiple beginner guides say a regular fitted athletic T-shirt and athletic shorts can be enough for a first class, especially if the shorts have no zippers or pockets. The better approach for many first-timers is to use safe gym basics first, then upgrade based on the class style and your comfort level, as explained in Arma BJJ's guide on what to wear to your first BJJ class.
That matters because it lowers the barrier to entry. You can try a class, make sure you like the academy, and then buy what fits your actual training schedule instead of guessing.
A simple first-class setup often looks like this:
| Class type | Fine for a first visit | Better long-term choice |
|---|---|---|
| No-Gi | Fitted T-shirt and safe athletic shorts | Rash guard, compression layer, grappling shorts |
| Gi | Borrowed or loaner gi if the academy offers one | Your own properly fitted gi |
If you're choosing gear for a child
Parents usually have two concerns. Will this be comfortable, and will my child be able to manage it without constant help?
Start with fit and ease. A child's gi shouldn't swallow them, but it also shouldn't feel stiff and restrictive. Kids need to move, fall, stand up, and tie things back together after drills. If the uniform is too large, sleeves and pant legs become a distraction. If it's too tight, they'll fight the outfit instead of learning.
A practical approach for kids:
- Choose simple, durable gear over flashy extras.
- Expect some growth but don't buy so large that the uniform bunches everywhere.
- Ask the academy what they require because kids programs sometimes have specific policies.
If you plan to compete
Competition clothing gets stricter. For gi training, IBJJF says gis should be made of cotton or cotton-like fabric, not so thick or hard that they hinder an opponent's grip, and sleeves should fall within approximately 1.5 inches above or below the wrist bone. Those fit standards are spelled out on the IBJJF uniform rules page.
That standard shows what good gi fit is aiming for. Snug, but not restrictive. Clean lines, limited excess fabric, and enough room to move without giving away sloppy grips.
This often creates a useful pathway:
- First class uses gym-safe basics or a borrowed uniform.
- Early training adds one dependable set of gear for your main class type.
- Competition prep means checking the exact rules before event day.
That's a much smarter progression than buying everything up front.
Your First-Class Packing Checklist
Packing for jiu jitsu doesn't need to be complicated. The best gym bag is the one that keeps your essentials separate, dry, and easy to grab when you're rushing out the door after work or school.
If you're still choosing a bag, this guide to tote bag options for busy lifestyles is useful for people who want something simple enough to carry daily but roomy enough for training gear.
What goes in the bag
Use this as a first-class default:
Clean training clothes
A gi if the academy told you to bring one, or fitted athletic wear if it's a trial no-gi class.Water bottle
You'll want it even if class is short.Mouthguard
Bring it if you have one.Sandals or flip-flops
These are for walking off the mat, into the bathroom, and around the facility.Small towel
Helpful after class, especially if you're heading straight back to work or errands.Basic toiletries
Soap, shampoo, deodorant, and anything else you'll want if you shower there.
The mental checklist matters too
Bring a few non-gear items as well.
- An open mind because everything will feel unfamiliar at first.
- A willingness to ask questions because coaches expect beginners to need help.
- A calm pace because nobody wins their first class by trying to look experienced.
If you're still wondering what to wear to jiu jitsu, the simplest answer is this: wear clean, fitted, gym-safe clothing that matches the class style, avoid anything loose or hard-edged, and upgrade only after you know what kind of training you'll stick with.
