Do You Need a BJJ Rash Guard to Train Brazilian Jiu Jitsu?
While you don’t need a bjj rash guard to train Brazilian jiu jitsu, it is highly recommended. Plus some bjj gyms may require you to wear a rash guard or even to wear their specifc gym bran rash guard.
However, if your gym doeson’t require one, you can train in a T shirt or compression shirt.
The issue with training in a T-shirt is that they can get in the way of training jiu jitsy by:
- riding up
- absorbing sweat
- getting caught by hands/feet of your training partner
Overall, its not recommended to train Brazilian jiu jitsu in a T-shirt. A rash guard is always recommend for any bjj training, but if you want to go the more affordable route there’s nothing wrong with training in a compression shirt.
BJJ Rash Guard vs Compression Shirt
| BJJ RASH GUARD | COMPRESSION SHIRT | |
| Garment Construction | Six Panel | Four panel |
| Stitch | Flatlock | Will depend on the manufacturer |
| Durability | Lasts 4-5 years | Lasts 1-2 years |
| Flexibility | More flexible (flatlock stitch) | Less Flexible (type of stitch can vary) |
| Waist Liner | May have rubber waist liner | Likely doesn’t |
| Breathable Arm Pit Fabric | Includes breathable armpit fabric | Doesn’t |
| Sublimated Designs | Yes | Not Likely |
| Price Range | Ave. $35-$80 | Ave. $15-40 |
Some people may think that a bjj rash guard is also a compression shirt but that is not exactly the case. Although very similar, there are differences in their composition, making the bjj rash guard the best type of gear for bjj practitioners.
Let us start with the material, bjj rash guards are made from six-panel material as compared to a compression shirt which is made of only four. This means, a bjj rash guard is more flexible, allowing you to move freely despite being body fit.
Another detail that makes a bjj rash guard different is the type of stitching used which is a flatlock. This type of stitching makes the bjj rash guard extremely durable and ready for the tugging and pulling that is part of the sport. Therefore, it can last longer compared to a compression shirt. Now typically, a compression can last around 1-2 years. But a bjj rash guard can last around 4-5 years because of how it was designed and made.
Now when comparing the price range, you can say that a compression shirt can somehow be cheaper to a bjj rash guard. But in the long run, the bjj rash guard is more practical because of its durability.
Reasons Why You Need a BJJ rash guard
We all know that BJJ is a full contact grappling sport. Therefore the reason why you want to wear a bjj rash guard is because it is your protective gear and it serves you a lot of purpose while training. Here are some of the reasons why:
- Protection against infection – We all know that training BJJ requires direct contact with your opponent and to the mat which can be dirty. With your rash guard, serving as a skin protective barrier gear, you can prevent infections like: ringworm and staph infection.
- Prevent mats mat burn– The most common cause of mat burn is having your skin rub against a hard or rough surface. Yes, with all the rolling on the mat and friction, there is a high chance of having the mat burn. A mat burn from rolling can cause pain that can lead to you being uncomfortable or even to an infection if not cared for properly. Therefore, wearing a BJJ rash guard is a good way to protect yourself.
- Improves grip – After several drills and rolling sessions, you are definitely bound to sweat causing you to have poor grip and making it hard to move. Now, your rash guard can help you with moisture control. This will allow you have firmer grip against your opponent and more traction.
- Injury prevention – A bjj rash guard uses material that provides you with a good compression. Now according to study, having compression can provide you with better blood flow and holds everything together during mat time. Therefore, giving you the additional protection that you need.
The History and Origin of the BJJ Rash Guard
The inception of rash guards can be traced back to the surfing community in the late 1970s and early 1980s.
Surfers used rash guards to shield their chest and ribs from the abrasive contact with surfboards, enabling them to avoid painful rashes caused by friction close to their bodies.
However, it wasn’t until the evolution of Brazilian Jiu-Jitsu that rash guards found their place in the world of martial arts.
BJJ pioneers and practitioners recognized the potential benefits of incorporating rash guards into their training gear, primarily as a means of protection against skin-to-mat contact and prevention of skin infections.
The use of rash guards in BJJ competitions quickly became the standard, leading to the development of specialized rash guards crafted explicitly for BJJ and other grappling martial arts.
What is the purpose of a rashguard?
The primary purpose of a rashguard is to provide a protective layer over the upper body during BJJ)training sessions or competitions.
This protection serves multiple functions, including
- shielding the skin from mat burns
- reducing the chance of bacterial infections
- and increasing the participant’s overall comfort
Wearing a rashguard, made from specialized materials such as spandex, polyester, or nylon, also prevents excessive sweat accumulation, ensuring that the practitioner remains relatively dry and comfortable throughout the session.
How Should a Rash Guard Fit
A bjj rash guard should fit well on you. This means, it should serve as initial protection of your body against outside forces, like the mats and your opponent.
Therefore, we can say that a correct fitting bjj rash guard fits tightly against your torso. Moreover, it should be able to provide you the flexibility required for bjj and not have your clothing get in the way – which is one of the main points of wearing a rash guard.
Your bjj rash guard should serve as initial protection of your body against outside forces, like the mats and your opponent.

In order to check if it is the right fit, you should always make sure that you are able to stretch it about an inch when you pull away from your body.
Moreover, make sure that it is not too loose. Why? Well, by having a loose bjj rash guard, you will be prone to possible injury and bacterial infection. On the other hand, having a bjj rash guard that is too tight can cause potential injury and blood flow restriction which is bad.
What Size Rash Guard Should I Get
Your BJJ rash guard is not just like any other sports or casual piece of clothing. Therefore, ensuring that you have the correct size is a must.
But what size rash guard should you get? Well, choose that is not loose. If you have a loose bjj rash guard, it will be hard to grapple. Moreover, you will put yourself at risk for possible injury.
Now, for tightness, make sure that it is not too tight. This means that you are able to move your limbs comfortably and its not tight on the neck. Thus, your blood flow is not restricted despite the tight hugging material.
If you are purchasing your bjj rash guard in the store, ask if you can try to compare sizing with your body and check elasticity to see it stretch. But if you are purchasing your gear online, make sure to measure yourself and compare your size to their size chart.
What’s a Rash Guard Made of?
A BJJ rash guard is made from different cloth materials that gives you a certain level of comfort, stretch, moisture protection and breathability. Typically it is made from the combination of different fabrics such as:
- Nylon
- Polyester
- Lycra
- Neoprene
- Spandex blend
- Others
Apart from the material used in your bjj rash guard, another garment construction that makes the rash guard stronger, thicker and has increased mobility compared to other garments is the use of six panels. Typically, in garment construction, a four panel is used.
Lastly, a bjj rash guard is made of flatlock stitches, wherein there is no additional fabric at the seam. A flatlock stitch is a reinforced stitching method. Thus making it extremely durable and ready for action.
Should You Wear a Rash Guard for Gi Training
Although not required in most gyms, it is still best to wear a bjj rash guard for Gi training.
This is because there are several advantages that you can gain from doing this. So, why wear a bjj rash guard of Gi training? Here are some of the reasons:
- Gi protection– We all know that one of the expensive gears that you use for BJJ training is your Gi and not everyone has multiple pairs. Now, by wearing a bjj rash guard underneath, you will be able to prevent the wear and tear of your uniform. Why? Well, your bjj rash guard serves as a protective barrier between your skin and the rash guard. Therefore, there will be little or limited sweat/fluid contact on your Gi. As we all know, the Gi can absorb sweat and during the training time, that it absorbs sweat, there will be bacterial formation on it and breaking of material.
- Blood flow – Even though you are training in Gi, it is still necessary to have excellent blood flow. If you wear a rash guard underneath your Gi, you are giving your body that light hug it needs that helps with compression and blood flow. Thus, making your oxygenation better while training or sparring.
- Skin protection – One thing to know about your Gi uniform is that it has a rough material. Now, with that being said, there will be a high probability of friction during your mat sessions. Therefore, by wearing your bjj rash guard, you get to protect your skin against possible injury and bacteria.

Should You Wear a Rash Guard for Nogi Training
If you are training Nogi then know that it is very important for you to wear a bjj rash guard. We all know that bjj is a full contact sport and your bjj rash guard is the layer of protection you have against the mats and your opponent.
Why? Well, we know that there is extreme risk for you to get rashes and mat burn from the sport. This is due to the high intense friction that can be created from certain positions and movements. You are also prone to getting in contact with your partner. Thus, your bjj rash guard serves as a skin barrier of protection.
Moreover, even though your gym or facility is extremely clean. You must still prioritize protecting yourself. You have to think about the germs left behind on the mats from previous use. Thus, using a bjj rash guard for Nogi training is essential.
Why do Jiu Jitsu Practitioners Prefer Wearing Long Sleeves?
Commonly, Brazilian jiu jitsu practitioners opt to wear long sleeve bjj rash guards compared to short sleeve ones.
Well, the most common reason behind is that a long sleeve bjj rash guard offers full coverage of the arms. Therefore, there is a bigger coverage of protection and compression for the practitioner.
How To Choose The Ideal BJJ Rash Guard For You
To select the ideal BJJ rash guard, consider factors such as material, fit, design, and compliance with competition regulations.
Make sure the rash guard is specifically designed for BJJ, offering the best blend of durability, flexibility, and comfort. BJJ-specific rash guards have reinforced stitching and are made from the most effective combination of materials like polyester and spandex.

Although, top quality is what you are looking for in a bjj rash guard, this does not mean that you have to buy the most expensive one. The important thing is for you to know what you should be looking for.
First thing is of course the material used for your bjj rash guard. This will be the main composition of your gear. Therefore, it is important to select a bjj rash guard made from great protective fabric. To add to that, choose those that have been tried and tested when it comes to durability.
Since you will be spending your money on your bjj rash guard, find something that will be with you in your martial arts journey for a long time. Another thing to consider is your body reacts to your bjj rash guard. Since bjj is a full contact sport, expect a lot of heat and sweat. Therefore, selecting a breathable quality rash guard is important.
Fit
Ideally, the perfect bjj rash guard fit is that you feel comfortable in it. Therefore, it offers compression on your body but not too tight or too restricting that can limit or restrict your movement. Other than that, it should also not be loose or floppy because this can become a hindrance in how you play your game. If this is the case, there is a possibility of skin exposure which can result in mat burn, bacterial infection, etc.
Moreover, if you are opting for a long sleeve bjj rash guard, purchase the one that also covers your wrist. Thus, offering full upper body coverage.
Material
There are many different materials that can be used for a bjj rash guard. This is not limited to being polyester, spandex blend, lycra and neoprene. Although it is recommended to choose a bjj rash guard made 100% from these materials or at least a mix of them, you must still choose something that you are comfortable in.
Durability
Since your bjj rash guard will be your long term gear for the sport, you must select a durable one. Aside from the material used for it, you must also take into consideration how it was put together. Typically, a bjj rash guard was stitched together with a flatlock stitch. Therefore, making it extremely ready for the full contact sport. One thing you can do is make sure that you are looking into a reputable brand (this does not expensive, but those with history of great wear and tear based on 1st hand reviews)
Breathability
Another factor to consider is the breathability of your bjj rash guard. Breathability is extremely important due to many different reasons. We all know that bjj is a full combat sport that requires exertion of effort. Therefore, you must prevent your body from overheating because of the exertion. Your bjj rash guard should be able to help you not to feel too stuffy, and prevent too much sweat.

Why Are Rash Guards So Expensive? (Are we overpaying for rash guards?)
The price of BJJ rash guards may appear steep, especially when compared to regular sportswear like t-shirts. This is due to several factors that contribute to their production cost and product quality.
The first reason is the specialized material used in rash guards, which typically consists of a blend of polyester, spandex, or Lycra. These fabrics are carefully selected for their durability, flexibility, and moisture-wicking properties, setting them apart from generic sports clothing.
The second factor that influences the cost of rash guards is the manufacturing process. Rash guards are painstakingly crafted to deliver maximum protection, comfort, and performance during BJJ training. This level of detail includes the incorporation of flatlock stitching, which reduces chafing and enhances the garment’s longevity.
Additionally, the process of sublimation – a technique that fuses the design into the fabric itself – ensures that the print will not peel or fade over time, unlike traditional screen printing.
Finally, the relative niche market for BJJ apparel contributes to the elevated price point of rash guards. BJJ is a specialized sport, and the demand for dedicated gear is narrower when compared to mainstream athletic clothing. As a result, the cost of producing high-quality BJJ rash guards is spread across a smaller consumer base, translating into higher individual prices. Despite their cost, investing in superior rash guards can enhance your overall training experience and provide long-lasting value.
How to Wash Your Rash Guard
One of your responsibilities as a bjj practitioner is to make sure that you come into class with a clean uniform. Read on as we provide you with instructions and tips on how you can wash your rash guard.
- Read care guide – Of course your bjj rash guard will come with an instruction on how you should be washing them. Therefore, making sure that you read it before doing anything is the best way to go. Each brand and material has its own way of care and by making sure you do these correctly, makes your bjj rash guard last longer.
- Make sure to avoid velcro – If you are washing your rash guard, make sure that it is not mixed with clothing (like your bjj shorts) that can break its thin polyester material.
- Turn it inside out – More often than not, your chosen rash guard most likely has your print of choice. Therefore to protect that sublimation, we recommend that you turn it inside out.
- Dry on low heat – Although it will depend on the rash guard care instructions, we recommend using low heat. The reason behind this is that you do not want to break the small polyester material used in your bjj rash guard by overheating it.
Other tips:
- If you have a delicate wash bag, then you can use that also for more protection.
- You can use fabric conditioner if you like. This all boils down to your preference. Just always make sure you read product labels.
- Once you get home, make sure to take out you bjj rash guard out from your bag.

Can you put BJJ rash guards in the dryer?
It is generally not recommended to put BJJ rash guards in the dryer.
However, if the rash guard is pre shrunk and you feel that it comes out cleaner when put in th dryer after washing, you may proceed at your own risk (I actually put some of my rash guards in the dryer since they end up smelling cleaner).
The heat generated by dryers can weaken the fabric’s elasticity and cause it to lose its shape, negatively affecting the overall performance and durability of the rash guard. A safer option is to air dry your rash guard to ensure it retains its original form and fit.
To air dry, gently shake out excess water and lay the rash guard flat on a clean surface, like a towel, or hang it on a drying rack. Keep in mind that direct sunlight may cause colors to fade, so it is best to dry your rash guard in a shaded area with proper air circulation.
IBJJF Rash Guard Competition Regulations
According to the latest rule book of IBJJ, these are the requirements for Nogi shirt and Rash Guards: Both genders must wear a shirt of elastic material (skin tight) long enough to cover the torso all the way to the waistband of the shorts, colored black, white, or black and white, and with at least 10% of the rank color(belt) to which the athlete belongs. Shirts 100% the color of the athlete’s rank (belt) are also permitted.
For black belt Nogi competitors, one thing to note for black belts is a small red area will be tolerated, but must not decharacterize the athlete’s rank color.
Tip: Make sure that when you are purchasing a bjj rash guard that you will be using for competition is to select one that is IBJJF approved. Typically, you can read that it is approved in the description of the item.

Frequently Asked Questions
Why Are Rash Guards So Expensive?

How Long Do Rash Guards Last?
Depending on use, care, and maintenance, rash guards should last 2-4 years. With consistent washing and care, a rash guard should last quite a while especially compared to T-shirts and compared to how much wear and tear they go through during jiu jitsu training.

Again, rash guard requires will vary heavily from gym to gym so always check with them directly.
Can You Train BJJ in a T Shirt?
While it is technically possible to train BJJ in a regular t-shirt, doing so is not recommended for several reasons.
1. T-shirts are typically made from cotton, which can absorb and retain sweat, making the shirt heavy, uncomfortable, and prone to the growth of bacteria and odor. This creates an unhygienic training environment and can pose health risks to both yourself and your training partners.
2. T-shirts do not offer the same level of compression as rash guards, which help to reduce muscle fatigue, promote blood flow, and minimize the risk of injury. The compression effect of rash guards is essential for aiding muscle recovery and enhancing overall performance during training sessions.
3. The loose fit of t-shirts can create safety hazards on the mat, as fingers or toes can become entangled in the fabric, potentially leading to injuries. In contrast, BJJ rash guards are specifically designed to fit snugly against the body, thereby reducing the risk of accidental entanglement during grappling.
