Understanding Jiu Jitsu Attire: Gi vs. No-Gi

First, it’s helpful to know that Brazilian jiu jitsu has two primary training formats, and your attire will differ for each. These are “Gi” jiu jitsu and “No-Gi” jiu jitsu. Most jiu-jitsu schools offer both types of BJJ class, though some may emphasize one over the other when you sign up for a Brazilian jiu jitsu class.

For Gi jiu jitsu, you wear a traditional uniform, commonly called a Gi. This uniform resembles those used in judo and allows for various grips on the fabric. These grips are fundamental to many techniques taught in a Gi class for Gi BJJ.

No-Gi jiu jitsu, true to its name, is done without the Gi. In these sessions, you will wear athletic clothing such as rashguards and athletic shorts or spats spats. The absence of Gi grips alters the dynamic, often leading to a faster pace and a greater emphasis on body control and wrestling-style holds; it’s a core part of training BJJ that focuses on BJJ grappling.

The Jiu Jitsu Gi: Your BJJ Armor

If your academy trains in the Gi, this jiu-jitsu Gi will be your main uniform. It’s more than just clothing; it’s a tool used in training and a symbol of your journey in Brazilian jiu-jitsu. Knowing a bit about it will help you choose wisely from the available Gi wear.

What is a Gi?

A jiu jitsu Gi, sometimes called a kimono, is a heavy cotton uniform made up of a jacket, pants, and a belt. The BJJ Gi is constructed to withstand a lot of pulling and grabbing, common in Brazilian jiu. The material of the traditional Gi also creates friction, which can be used to your advantage during grappling exchanges.

Many practitioners feel the Gi helps to slow down the pace of jiu jitsu. This can be beneficial for learning techniques properly and understanding leverage. It also provides a specific set of grips and chokes that are particular to Gi training, distinguishing it from other mixed martial arts.

The historical roots of the jiu-jitsu Gi trace back to judo gis, adapted over time for the specific demands of ground fighting. Training in a Gi BJJ setting fosters a methodical approach to problem-solving. This helps develop patience and strategic thinking.

Key Components of a Gi

Your BJJ Gi has three main parts: the jacket, pants, and belt. Each part is important for function and tradition in the jitsu school environment. Understanding these components will help you select the proper equipment.

The jacket is usually made from a single piece of cotton, with a thick, reinforced collar, often made with EVA foam for structure and quick drying. The collar is a frequent target for grips and chokes, so it needs to be tough. Gi jackets come in various weaves, like single, pearl, or gold weave, which affect their weight, durability, and how they feel; some also feature triple or quadruple stitching in high-stress areas for longevity.

Gi pants are typically made from cotton canvas or ripstop material. Ripstop is lighter, more breathable, and tears less easily. The knees are almost always reinforced because you spend a lot of time on them, and some pants offer reinforced gussets for better mobility. They are secured with a drawstring at the waist, which can be a stretchy rope or a flat cotton type.

The belt holds your jacket closed. More importantly, it shows your rank in jiu jitsu, marking your progress. You’ll start with a white belt and progress through different colors as you learn and grow in your jiu jitsu class.

Choosing Your First Gi

Picking your first Gi can feel like a significant step as you prepare for Gi classes. There are a few things to keep in mind. Consider size, material, color, and your budget when selecting your Gi.

Sizing can be confusing because it often uses an ‘A’ for adults (A0 to A6), ‘F’ for female-specific cuts (F1-F5), or ‘M’ for male-specific fits, plus kids’ sizes (M000-M4). Some brands also offer ‘L’ for Long, ‘S’ for Short, or ‘H’ for Husky/Heavy (e.g., A2L, A1H). Most brands have sizing charts on their websites; however, it can vary, so asking training partners or your instructor at your jitsu school about their experience with different brands is helpful.

Materials and weaves matter for comfort and durability. Lighter single weaves are good for hot weather or if you prefer less weight, but may not last as long as heavier pearl or gold weaves. Pearl Weave Plus and Crystal Weave are other options offering different balances of weight and strength. Heavier Gis can be harder for opponents to grip, which many find advantageous, while lighter Gis might be preferred for competition weigh-ins. Ripstop pants are common, but some prefer traditional cotton drill pants for their feel. The weave also affects breathability and how much a Gi might shrink after washing.

Traditional Gi colors are white, blue, and black. Many academies prefer beginners to start with a white Gi. For competitions, organizations like the International Brazilian Jiu-Jitsu Federation (IBJJF) have specific rules about Gi colors (e.g., white, royal blue, black are usually permitted) and patches, so it’s good to be aware of those if you plan to compete. Some jiu jitsu schools have their own rules regarding Gi wear, sometimes requiring an academy-branded gi.

Gis range in price quite a bit. As a beginner, you don’t need the most expensive Gi on the market. A good quality, budget-friendly Gi will serve you well as you start your journey in your brazilian jiu jitsu class. Higher prices often correlate with enhanced durability, specific cuts for better fit, or established brand reputation, but many starter Gis from reputable, less flashy brands offer excellent value.

Here’s a quick comparison of common Gi weaves:

Weave Type	Typical Weight	Pros	Cons
Single Weave	Light (300-550 GSM)	Lightweight, breathable, affordable.	Less durable, can stretch more.
Pearl Weave	Medium (400-550 GSM)	Good balance of weight & durability, common.	Can be slightly rougher initially.
Gold Weave	Medium-Heavy (500-900 GSM)	Durable, soft after breaking in.	Heavier, can shrink more if not pre-shrunk.
Double Weave	Heavy (650-1050 GSM)	Very durable, hard for the opponent to grip.	Heavy, less breathable, can be expensive.
Ripstop (Pants/Lightweight Gis)	Very Light	Lightweight, tear-resistant, dries quickly.	Can be less comfortable for some, sometimes not allowed for jackets in all competitions.

This table gives a general idea; variations exist between brands. Always check product specifications. Many people starting out find a pearl weave Gi to be a good first choice for their BJJ gi.

Gi Care Essentials

Keeping your Gi clean is very important for hygiene and respect in your jiu jitsu school. A dirty Gi is unhygienic and disrespectful to your training partners. Always wash your Gi after every single training session, especially after intense Gi classes.

Wash it in cold water to help prevent it from shrinking too much; most Gis are made of cotton and will shrink somewhat, especially in warm or hot water. It’s best to hang it to dry instead of using a machine dryer, as heat can damage the fibers and cause more shrinkage. Some people say a tiny bit of shrinkage can help an initially slightly-too-large Gi fit better, but it’s a gamble, and some Gis come pre-shrunk to minimize this issue.

Avoid using bleach, as it can weaken the fabric over time and yellow white Gis. If you get blood on your Gi, treat it immediately with cold water. For applying patches, sewing is generally more durable than iron-on, and there are specific IBJJF rules for patch placement if you plan to compete. A clean Gi is a sign of a respectful student; nobody wants to roll with someone in a smelly, unwashed uniform, which is crucial for preventing skin infections during BJJ grappling.

What to Wear UNDER Your Gi/No-Gi Gear

What you wear underneath your main jiu jitsu attire is also important for comfort, hygiene, and support. This layer is a key part of your overall class wear. Consider these options before your next jiu jitsu class.

For men, compression shorts or athletic briefs are commonly worn under Gi pants. These provide support and a hygienic barrier. Some men also choose to wear a rashguard under their Gi top, especially in colder environments or simply for personal comfort and to wick sweat away from the body.

For women, a supportive sports bra is vital. High-impact sports bras are recommended due to the dynamic movements in Brazilian jiu-jitsu. Many women also wear compression shorts or spats under their Gi pants for comfort and coverage. For No-Gi training, a sports bra is typically worn beneath the rashguard. While some academies might permit tank tops or crop tops under a rashguard, the rashguard itself should be the primary outer layer for skin protection and hygiene. Avoid wearing only tank tops or crop tops without a rashguard in most No-Gi settings unless your specific jiu jitsu school explicitly allows it.

No-Gi Jiu Jitsu: What to Wear When the Gi Comes Off

When it’s time for a No-Gi BJJ class, the heavy cotton Gi stays in your bag. The athletic attire for No-Gi is all about movement, preventing friction, and hygiene. You’ll need different items, specifically rashguards and appropriate BJJ shorts or spats spats, to properly prepare for what to wear for jiu jitsu in a No-Gi setting.

The Rash Guard: Your Second Skin

A rash guard is a must-have for No-Gi and forms a core part of your grappling gear. These are athletic shirts usually made from spandex, polyester, nylon, lycra, or a blend of these materials. They fit snugly to your body to wick sweat and minimize loose fabric.

Rash guards protect your skin from mat burn, which is like a friction burn from the mats. They also help to wick moisture away from your body, keeping you a bit drier. Perhaps most importantly, they create a barrier between your skin and your training partners’, which is good for hygiene and reduces the risk of skin infections when training BJJ.

You can get short-sleeve or long-sleeve rash guards. Long sleeves offer more protection from scratches and germs, and some prefer them in cooler temperatures. Some schools or competitions may require ranked rash guards, which have colors corresponding to your belt level, so check if your academy or any mixed martial arts event has a preference for your athletic attire.

Shorts or Spats (or Both.)

For your lower body in No-Gi, you’ll typically wear shorts or spats (compression pants), or sometimes both. The most important rule is that they must not have any pockets, zippers, buttons, or any hard materials. These can catch fingers and toes, leading to injuries, so you must avoid clothing with these features.

BJJ specific shorts or MMA shorts are made for grappling. They often have a Velcro closure and an internal drawstring to keep them secure, and some feature stretch panels in the crotch for better mobility. The fabric is usually durable and allows for a good range of motion. Styles range from shorter Vale Tudo shorts (very tight, minimal fabric) to longer board-short style grappling shorts; just be sure they are designed for grappling to avoid hard objects. It’s best to avoid shorts that are too baggy.

Spats are tight-fitting compression pants, similar to what runners might wear, and are a popular choice for grappling gear. They offer the same benefits as rash guards for your legs: protection from mat burn, moisture-wicking, and hygiene. Many people wear spats under their grappling shorts for an extra layer of protection or modesty, but some wear them on their own, academy permitting. Wearing spats can also provide a bit of friction, which can be helpful in certain positions. Always choose tight athletic clothing that allows full movement.

Essential Protective Gear for Jiu Jitsu

Beyond your main Gi or No-Gi attire, there’s some protective gear to consider. While not always mandatory, these items can help prevent common injuries and allow you to continue training safely. This protective gear is a part of knowing what to wear for jiu jitsu safely, and investing in proper equipment can be very beneficial.

Mouthguard: Protect Your Smile

A mouthguard is highly recommended for jiu jitsu. Accidental elbows, knees, or head clashes can happen during BJJ training. A mouthguard protects your teeth, lips, tongue, and jaw from impact, helping to prevent injuries.

The most common type is a boil-and-bite mouthguard, which you can get at most sporting goods stores. You soften it in hot water and then bite into it to create a custom fit. For a better fit and potentially more protection, a dentist can make you a custom mouthguard, but these are more expensive. Remember to clean your mouthguard after each use and store it in a protective case.

Groin Protector (Cup): Optional but Recommended for Men

A groin protector, or cup, is optional for men but many choose to wear one as part of their protective gear. Accidental impact to the groin area can be incredibly painful. If you decide to wear one, make sure it fits well and is worn with compression shorts or a jockstrap designed to hold it in place securely.

Not all male practitioners wear one as some find them restrictive. However, many who have experienced an accidental groin shot quickly become advocates. It’s a personal choice based on comfort and perceived risk.

Ear Guards: Preventing Cauliflower Ear

Cauliflower ear is a common deformity in grappling sports like brazilian jiu-jitsu, caused by repeated trauma or friction to the ears. The ear fills with blood, and if not drained, it hardens into the characteristic swollen shape. Ear guards, similar to what wrestlers wear, can help prevent this condition.

They aren’t usually worn by everyone, but if you’re training frequently, engaging in a lot of hard sparring, or are concerned about cauliflower ear, they are a good investment. There are various styles of headgear, so choose one that fits snugly and stays in place during rolling. Using ear guards is a proactive step to prevent injuries.

Knee Pads/Elbow Pads

Some people choose to wear knee pads or elbow pads, another form of gear protective. This is usually if they have pre-existing joint issues, are recovering from an injury, or just want extra cushioning. If you find your knees or elbows getting sore from takedowns, extensive guard work, or a lot of mat work like knee-on-belly, these can provide some relief and help you continue training comfortably. Options range from simple neoprene sleeves to more padded versions.

What Else to Bring to Jiu Jitsu Class

Being prepared for your jiu jitsu class or BJJ classes means more than just having the right clothes on your body. There are a few other items you should always have in your gym bag. Think of this as your extended list of what to wear for jiu jitsu and how to be prepared for everything your jitsu school throws at you.

Always bring a water bottle, preferably a large, reusable one. Hydration is crucial, and you’ll be sweating a lot during intense BJJ grappling. Having your own water means you don’t have to leave the mat area or rely on a shared water fountain as much. A towel is another good idea; many bring a small one for wiping off sweat during breaks and a larger one if they plan to shower at the academy after class. Some gyms require you to bring a towel to help keep the mats clean from excessive sweat.

Flip-flops or sandals are essential. You should wear them whenever you are off the mats, especially when going to the restroom or walking around the jiu jitsu school. This helps keep the mats clean and prevents tracking dirt and germs onto the training surface where people will be grappling. Many sources on gym hygiene consistently stress this point for safety.

Consider bringing athletic tape for your fingers and toes. This is common for those who do a lot of Gi gripping or have minor sprains. It can provide support and prevent skin irritation.

Finally, have a separate bag or compartment for your sweaty grappling gear after training. You don’t want your wet, used uniform mixing with your clean clothes or stinking up your main gym bag. An antimicrobial bag or even a simple plastic bag can contain odor and moisture, reminding you to wash your gear as soon as you get home. Can’t wait to train if you’re always prepared.

Hygiene: The Unspoken Dress Code

While not something you physically wear, hygiene is perhaps the most important part of your jiu jitsu preparation, especially for close-contact brazilian jiu. Jiu jitsu is a sport involving constant physical contact. Maintaining good personal hygiene shows respect for your training partners and keeps everyone in the jiu jitsu school safe and healthy.

This means showering regularly and always coming to class clean. Wear freshly laundered Gis and No-Gi attire, including rashguards and spats, for every single session. Rewearing dirty gear is a major health risk, promoting bacterial and fungal growth, and is very unpleasant for everyone you train with.

Keep your fingernails and toenails trimmed short. Long nails can easily scratch or cut training partners during BJJ grappling. This simple step prevents a lot of unnecessary minor injuries and is a basic expectation at all jiu-jitsu schools.

If you have any cuts, scrapes, or skin infections, cover them properly with athletic tape or a bandage before your jitsu class. If you have a contagious skin condition like ringworm or staph, you must stay off the mats until it’s completely healed. Consult a doctor if you suspect an infection, as emphasized by health resources for contact sports safety for community well-being. Don’t worry about missing a few classes; your health and your partners’ health come first.

Using deodorant is a good idea, though some prefer unscented options. And yes, even fresh breath is part of good mat etiquette. Nobody appreciates close contact with someone who neglected this. Think of good hygiene as a crucial, invisible part of your attire and overall readiness to continue training.

Where to Buy Your Jiu Jitsu Gear

Once you know what you need, you might wonder where to get it. There are several good options for buying your jiu jitsu Gis and No-Gi wear, including the BJJ Gi and other specific athletic clothing. You can find grappling gear that fits your style and budget without too much trouble.

Many online retailers specialize in BJJ and MMA gear. They often have a wide selection of brands, styles, and sizes for all your Gi wear needs. Look for sites with good reviews and clear return policies, especially when buying your first Gi, as getting the size right can take some trial and error. Some popular online stores include Fighters Market and BJJ Warehouse, and many Gi brands sell directly from their own websites.

If you have a local store that sells martial arts supplies or mixed martial arts gear, that can be a great place to shop. You can try things on for size and feel the materials of the athletic attire. The staff might also offer helpful advice for your specific needs, whether it’s for a Gi class or no-Gi training.

Often, your own jiu jitsu academy will have a pro shop or sell basic proper equipment. Buying from your academy can be convenient and helps support your school. They might even have specific uniform requirements or recommendations for your Brazilian jiu jitsu class, so it’s always good to check with your instructor first. Some jiu jitsu schools even offer rentals or a free trial period for gear when you first start.

Common Mistakes to Avoid When Choosing What to Wear for Jiu Jitsu

As you get started, it’s easy to make a few mistakes with your gear. Knowing what to avoid wearing will help you integrate smoothly and train more effectively. Learning about common pitfalls helps you focus on what to wear for jiu jitsu properly and avoid clothing that could be problematic.

Avoid wearing regular loose cotton t-shirts and basketball shorts, especially for No-Gi. Cotton gets heavy when wet with sweat, stretches out, can easily get caught on fingers or toes, and can rip. Rash guards and proper grappling shorts, often BJJ shorts, are much better and safer for everyone involved in the class.

Absolutely no clothing with zippers, buttons, snaps, pockets, or any other hard materials. These can injure you or your training partners significantly—imagine a finger getting caught in a pocket during a scramble. Always check your athletic shorts and remove any hard objects or protruding elements. Some gyms require specific types of shorts, so avoid shorts with drawstrings on the outside if possible.

Choosing the wrong Gi size is a common beginner mistake. A Gi that’s too big can be cumbersome and provides excessive material for opponents to grip. A Gi that’s too small can restrict your movement, may tear more easily at the seams, and might not be allowed in competitions if it’s deemed too tight or short. Refer to size charts, but also seek advice if unsure. Remember that some Gis shrink, so factor that in. This is particularly important for your jiu-jitsu Gi.

Never neglect the hygiene of your gear; this cannot be stressed enough. Wearing a dirty Gi or rash guard is a serious offense in the jiu jitsu community due to health risks and lack of respect. Wash everything after each use, without exception, to maintain a safe training environment for your mixed martial arts training.

Finally, always check if your academy has specific rules about uniforms. Some schools have preferred Gi colors (e.g., only white or blue Gis for certain belt levels or for all Gi classes), or require students to wear the academy patch. It’s best to ask your instructor before buying anything, especially for specialized class wear or if you are considering joining different jiu-jitsu schools.

Conclusion

Figuring out what to wear for jiu jitsu doesn’t need to be stressful. Your primary concerns are getting a well-fitting Gi for Gi classes and suitable rash guards and shorts/spats for No-Gi sessions.
