Before rash guards existed, BJJ practitioners would often wear cotton t-shirts that could become very uncomfortable after hours of rolling. Many people who wear a cotton t-shirt under Jiu Jitsu Gi’s also find it very uncomfortable as well.
I always recommend wearing rash guards in Gi or No-Gi because of the sweat-wicking technology found in rash guards. But not all rash guards are made the same! Here are my favorite Jiu Jitsu rash guards in 2023…
Why You Should Wear a Rash Guard
The rash guard is almost necessary in no-gi grappling because of the benefits it brings. However, it’s also very useful even under the gi. Although some people feel less restricted without a rash guard, it still holds many benefits when compared to a cotton t-shirt or any other compression shirts. I personally believe that you should wear whatever is most comfortable for you, however here are the benefits of wearing a rash guard:
- Muscle Compression helps prevent injury. There have been many studies on the correlation between wearing a rash guard during rolling can help speed up injuries due to the compression of the muscles. Just as there are compression braces that reduce injuries of the knees, ankles and elbows, rash guards can also reduce the occurrence of minor injuries.
- Reduce the spread of bacteria. When you’re rolling around, especially in a gi, it’s common practice to open the gi in order to destabilize your opponent, setup for gi chokes, or to use as leverage for a pass. During intense rolling sessions the gi will naturally open, exposing your opponent’s chest. This exposes much more skin surface area and increases the chance of bacteria exchange (which is a big no-no).
- Wick away moisture for better grips. I often find myself resetting my gi and re-aligning my belt after every few minutes of rolling. The more I roll, the more sweat accumulates. This increases the chances of me transferring that sweat to my hands in between rounds. This can be a serious disadvantage when trying to take advantage of an opponent in a submission such as a Kimura or arm bar. Sure, being sweaty can work to your benefit by slipping out of submissions, but more than likely it will work against your favor. Wearing a rash guard, will help alleviate some of that sweat transfer.
- Prevents mat burn. This is one of the original purposes of wearing a rash guard. When rolling no-gi, skin contact on your typical BJJ mat can cause friction scars which hurt like hell. Although the gi provides a barrier between the mat and your skin, it can worsen friction from rolling. The weave patterns on gi’s are specially designed to be strong and allow for griping, but it also creates a lot of unwanted friction. This is especially true for elbow passes or any other movements that require you to plant part of your arm on the mat. Wearing a rash guard can help avoid some of that friction as it’s surface is a lot smoother than your skin.
Based on the criteria above, here are my top picks for rash guards.

What’s the Difference Between Rash Guards and Compression Shirts?
Many people are surprised to find out that rash guards and compression shirts are not the same thing. In fact, all rash guards are not created equally, which is why we’ll review some rash guards below.
Typical compression shirts are made of four panels and are not designed for constant contact and friction. Movements are restricted while wearing a compression shirt when compared to a rash guard. A compression shirt is also much more likely to ride up your abdominal and back while rolling, which is super uncomfortable (you’ll end up adjusting your compression shirt during rolls).
On the other hand, good rash guards are constructed with a minimum of six panels (as compared to four in compression shirts). The stitching in rash guards is much more durable and built to resist sleeve pulls and stretching (similar to how gi’s are constructed).
Bottom line is that rash guards are much more durable than compression shirts. I highly recommend picking up a few pairs of rash guards if you’re a serious Brazilian Jiu Jitsu practitioner. You’ll save time and money by investing in a few quality rash guards rather than continually buying cheap compression shirts that will get ruined within weeks of rolling.
Rash Guards were originally designed for surfers to wear underneath their wetsuits to stop chafing (gross right). However, as surfers started moving into Brazilian Jiu Jitsu culture, so did their rash guards. So I guess you have those Cali surfers to can thank for all your comfortable roll sessions.
Don’t Forget to Buy the Right Color Rash Guard
You’ve probably noticed a common color theme of white, blue, purple, brown, black, and red rash guards. When competing in IBJJF events and tournaments, you’re required to wear the color of your proper BJJ belt ranking. So before you buy a rash guard for competition, keep in mind that when you enter a No-Gi IBJJF competition you’re required to wear a rash guard that is at least 10% of your ranked color.
