no gi rashguard in action

When you’re training Brazilian jiu jitsu, you’ll find that wearing the gi on it’s own can be very uncomfortable, itchy, hot and can even cause rashes and skin burns. That’s why it is very important to wear a rash guard under your jacket to keep your skin protected and you focus on your sport rather than on whether or not you’re comfortable in your clothes.

Before you even think that maybe you don’t need to buy your own rash guard or you don’t need one while you’re training, then make sure you check with your gym first. A lot of gyms require that you wear rash guards under your gi to prevent the spread of everything from skin conditions or just sweat between opponents while grappling.

Rashguards are made from a stretchy, spandex material that is quick-drying and hugs your body. If you’re not wearing one under your gi, then you could be exposed to burns from your gi, burns from the mat and irritations from your opponent. A rash guard is important and necessary when you’re training and competing.

A lot of athletes like to wear rash guards just to help them sweat a bit more, especially if they’re trying to cut weight. Your rash guard is quick drying, but will allow you to sweat a lot more when you’re working. This is great for cutting weight or just trying to lose a few pounds.

Benefits of Rashguards

  1. Protection Ligaments and Muscles
  2. Easier to Warmup
  3. No Excess Sweat
  4. Keep Blood in Your Muscles While Training

So why wouldn’t you wear just a regular shirt under your gi? Well a cotton t-shirt can get soaked and saturated with your sweat, which means that it can get heavy and stretch out. This can be very uncomfortable while you are training and can be distracting. You don’t want your attire to weigh you down or make you feel slimy.

There are a lot of rash guards on the market, and they are made for many things other than just Brazilian jiu jitsu. There are rash guards for surfing, MMA, and outdoor sports. These will be of varying thickness and prices, and what you want to use your rash guard for will help you determine which one to buy. You can use any rash guard you are comfortable in when training BJJ, but you should make sure you know what you are buying before you spend your money.

There are a few things to consider when buying your own rashguard. You want to make sure you have the right attire for you and your training

Things to look for when buying a bjj rash guard

  1. Thickness
  2. Stitching
  3. Brand
  4. Sleeves
  5. Style


If you are planning on cutting weight or losing pounds when you are training, and you want to do everything you possibly can for that, then you should consider buying a thicker rash guard. You can get them specifically for BJJ, but any rash guard that is made for surfing or outdoor sports will be made of a thicker material, unlike a lightweight gi

If you don’t want to sweat that much or simply are wearing a rashguard because you’re protecting your skin from burns and skin conditions, then you don’t necessarily have to buy one that is very thick. An MMA rash guard will be thinner to help keep you cool.


During BJJ, your rash guard will take a lot of damage, so it’s important to have good stitching that won’t rip open. You want to look for flatlock stitching with four or five threads. This ensures that the top you’re wearing won’t rip at the seams and come apart, wasting the money you put into it.


Different companies make rash guards for different things. They come in different prices, different thicknesses and different designs. You can buy a rash guard for under $10 or up to $70 or more. It depends a lot on the company you’re buying from. More popular brands will cost more, but they might also last you a little bit longer.

Also, if you want a different style rash guard than for BJJ simply because you’re more comfortable in it, then go ahead and buy a brand that promotes for surfing or football or whichever style you prefer.


Your sleeves will be another personal preference. Some people like long sleeves when training. Long sleeves offer more protection from infections like staph or ringworm, and they also keep more of your gi off of your skin, which means that you can focus more on your training and worry less about burns and irritation.

However, shorter sleeves can keep you a little bit cooler. Whichever sleeve you feel more comfortable training in is the one you should buy. If you have no preference, go ahead and get a few of each to switch it up.


Before you get a cool and flashy style, make sure that if you’re going to compete that you have a few rash guards that are regulation for competition. Often this means that they will match your belt or be plain. The next most important thing to think about with style is how the logo or any detail is put onto the rashguard.

Anything that is screen printed or pressed on could peel off when your top is wet with sweat or from pressing against the mats. You don’t want pieces of plastic logo to come off when your training, and you also don’t want your rashguard to get ruined. It’s better to get a logo and style that is designed into the shirt or the fabric is dyed so you don’t end up ruining your gear.

Also, there are a lot of choices for style, so make sure that you get one that you like. You will find a lot of styles and colors in your budget.

There are so many types, colors, brands, styles and sizes of rash guards on the market, and there are so many things they can be used for, so it can be difficult to find the one you like the best. We have a few of the ones we like best, so we’ve reviewed them here for you. These are our favorite Brazilian jiu jitsu rash guards.
