  • IBJJF Approved

Elite Sports lead the way in high-quality, durable, and affordable gear such as training bags, headgear, and MMA gloves. Often you can’t find both long-lasting premium quality at a good price, but Elite Sports carved their way into the world of MMA and BJJ gear with this ethos.

The combination of polyester and spandex allows both flexibility but also breathability; this is incredibly important in BJJ. All good rash guards will be made predominantly from polyester. Cotton clothing when rolling in BJJ or MMA is very hazardous. The biggest disadvantage of a cotton t-shirt is that when cotton gets wet through sweating, it becomes very stretchy. You do not want stretchy clothes when rolling in BJJ or MMA because toes and especially fingers can get caught, twisted, and this leads to unwanted injuries.

Not only that but this rash guard boasts a very advantageous flatlock seam, which removes any additional flaps or bulk that you typically see in regular tees or jumpers. This will eliminate chafing, rubbing, and snagging on your body parts.

Whilst most rash guards will promise faster recovery and performance due to the compression element of the top, this will be such a marginal gain that you won’t notice it. The takeaway here is that the compression top will be a tight fit that gives you comfort knowing you can move freely without worrying about snagging the wrists, arms, or arm-pits during your fast-paced BJJ or MMA sessions.

Sanabul’s high-quality Essentials long-sleeve is a must-have due to its affordability, quality, and quick-dry material. With the option of 6 different colors, you can have one rash guard for each session throughout the week. Reinforced under-arm stitching is a great addition to this compression top as typically that area gets a significant amount of heavy contact (think underhooks and guillotines) and this ensures the long-life and anti-rash effect of the rashguard after hours on the mat, for which you’ll need ample protein and rest.

The Sanabul Essentials long-sleeve comes in sizes from small all the way up to XXL which supports practitioners of all sizes. This version is the long-sleeve which is definitely the preferred option in most cases as it provides extra grip during long and sweaty sessions. This is especially important when you need your own arm as a stable grip in moves such as the kimura or armlock. The additional benefit to long-sleeve compression tops is that arm sweat doesn’t drip down to your hands which will negatively impact your grip.

The versatility of this BJJ rashguard extends beyond the mat. If you love outdoor activities such as surfing and paddle boarding and spend a lot of time in the sun then you’ll love the UV SPF 50 protection across your upper body.

However, Sicchic has really cornered the female rash guard market with their vibrant and colorful designs that not only feel good but fit well too.

While on the higher-end of the affordability scale, you’re paying for good quality polyester which not only helps to wick sweat away from the body (therefore cooling body temperature) but also an amazing design that will stand out in your training sessions.

A larger individual in both muscular and body fat will need to look at either XL or XXL rash guards. Rash guards for BJJ are already tight, but having one that’s too small, or shrunk in the wash is not only uncomfortable but restricting. Hayabusa Geo Compression has an answer to this and offers larger sizes perfect for the larger person.

The Geo Compression rash guard comes with a comfortable fit, runs up to XXL, and provides unrestricted movement with its 84% polyester/14% spandex material – a perfect combination for a multi-stretch rash guard that will work well against any opponent, even your grappling dummy!

The silicone waistband is great to keep everything in place. Often with smaller rash guards your ‘power belly’ can slip out during intense rolling sessions which can be somewhat embarrassing and uncomfortable, taking your mind out of the game. Although, you should never feel bad about this as you train with purpose and reason, continuing to do so will only breed solid results.

To ensure you keep this rash guard at the right size, machine wash cold and hang to dry. Dry cleaning isn’t necessary.


Do rash guards work?

BJJ rash guards work to prevent a lot of unwanted risks during training such as fingers, hands, and feet getting caught in loose fitting clothes, as well as keeping enough friction and dryness between you and your (sweaty) opponent in No-Gi Jiu-Jitsu. In addition, wearing a rash guard is much more hygienic, creating a barrier between you and unwanted bacteria from your opponent, their clothes, and the mat.

Lastly, the name rash guard is there because the material and and long-sleeve element is there to protect you from rashes, or burns from the mat. Anyone who has experienced mat burn will know it is horrible, and can develop into a nasty infection if untreated or poorly maintained.

Should rash guards be tight?

A BJJ or MMA rash guard should be fairly tight, but not restrictive of your movements, breathing, or blood flow. If you’ve never worn a rash guard before it may feel uncomfortable, but when you get used to it after a few sessions you’ll feel fine.

The tightness ensures that no loose material catches onto your own or your opponents body parts such as fingers or toes, which is known to leave nasty injuries. A loose t-shirt, especially when drenched in sweat, will hinder your opponents abilities to move, underhook, and grapple with your fairly – this isn’t good gym etiquette.

Some large men and women may feel uncomfortable in clothing that’s very tight, but remember, if you’re training in BJJ or MMA you’re participating in a high-intensity sport and trying to better yourself. Your training partners become family and won’t ridicule you for turning up in a tight top.

What’s the difference between a swim shirt and a rash guard?

A swim shirt is a loose fitted top that is used in hot conditions to prevent sun damage. They provide UV ray protection that doesn’t wash off and typically come with a high UPF rating depending on the quality. Swim shirts are more like regular shirts with the added sun protection and are seen as more comfortable to wear than a rash guard for all day use.

A rash guard is tightly fitted top that can be used in more extreme summer sports like surfing, which can also provide UV protection and anti-chafing capabilities. Their primary use is to prevent the user from rubbing against and getting friction burns from surfaces such as a surfboard. Rash guards are also very commonly used in Brazilian Jiu-Jitsu or Mixed Martial Arts. For the same reasons, preventing mat burn, but also a much more hygienic way to roll or perform close combat activities.

Can you swim in a rash guard?

Yes, you can swim in a rash guard as that is their primary purpose. They are typically made from high polyester material which means quick drying unlike a cotton alternative.

What do you wear under a rash guard top?

In almost all cases you shouldn’t wear anything under a rash guard top as that is your base layer. Good quality rash guards will wick sweat away and keep your body cool. If you were to wear another layer underneath you run the risk of overheating if performing high-intensity activities such as Brazilian Jiu-Jitsu or some form of martial art.

Can you tan through a rash guard?

You can tan from some brands of rash guard if they don’t come with UV protection. Rash guards for surfing will almost always come with some form of UV protection, however, those designed for BJJ and MMA may not. Be sure to check before buying.

The Sanabul Essentials Long Sleeve does come with UV protection so you’ll be protected and won’t tan.

Do rash guards make you hot?

While it may seem that wearing a tight base layer such as a rash guard will make you hot, they are designed with “clima-cooling” fabric that wick sweat away from your body and ensure a controlled body temperature. Because rash guards are not made from cotton materials but rather polyester and spandex, this will allow for better breathability through your skin.

Do you wear a bra under a rash guard?

Depending on the size of a woman’s breasts, a rash guard alone may be fine. If a woman’s breasts are on the larger side then a sports bra is recommended, and allowed by the IBJJF rules.

Do you wear a rash guard under a GI?

You can wear a rash guard underneath a Gi for hygienic purposes, and in face some BJJ studios will require this. Creating a physical barrier against your opponent, their potentially dirty Gi and the mat is hugely important for good health and hygiene. The other very important factor for wearing a rash guard is to protect your BJJ Gi for a long time. If you train traditional Brazilian Jiu-Jitsu, you’ll know that sweat rot can destroy a good Gi, and a rash guard can be the best way to avoid ruining a great Gi.
