Short sleeve or long sleeve? It's one of the most common question we get asked when it comes to BJJ rashguards.

And we're not talking about just about looking good on the mats. Whether you train exclusively nogi, gi, or a mix of both short sleeve and long sleeve rashguards have pros and cons for both training styles.

Short Sleeve vs Long Sleeve Rashguard

Don't sweat it, I've got your back (and your arms). Let's break down the pros and cons of each style, so you can make an informed decision and focus on what really matters - crushing it on the mats.

The Importance of Wearing a Rashguard

Okay, before we dive into the differences of short sleeve vs long sleeve rashguards, let's get something out of the way first.

Competition aside, please for the love of your training partners - wear a rashguard during everyday training!

Rashguards are the first defense layer for preventing skin infections on the mats. Plus, I can guarantee you that none of your training partners want your sweaty chest in their face. NONE OF THEM.

Trust me, I've seen firsthand how much of a difference the right rash guard can make. When you're rolling around on the mats, your skin is constantly coming into contact with your training partners and the mat itself.

Plus, a good rash guard is made from moisture-wicking material that helps keep you dry during intense training sessions. And when you stay dry, you're less likely to create an environment where bacteria and fungi can thrive.

Short Sleeve vs Long Sleeve Rashguards

Now that you know why a rash guard is so important, the next question is: short sleeve or long sleeve?

Both options have their pros and cons, and the right choice for you will depend on your personal preferences and training style.

To keep this short and sweet, short sleeve rashguards are more popular for those training nogi for a few reasons.

If you're someone who tends to overheat during intense training sessions, a short sleeve rash guard might be the way to go. Short sleeves allow for more ventilation and can help keep you cooler and more comfortable on the mats.

A short sleeve rashguard will also provide a bit more freedom of movement in the arms, which can be helpful for certain techniques and positions.

On top of that, it makes it way harder for your opponent to get good wrist control when training nogi. Whereas a long sleeve rashguard will provide significantly more grip compared to bare skin, especially when both athletes are sweaty.

When wearing a BJJ gi, most practitioners prefer to wear a long sleeve rashguard. 

Why? Long sleeve rashguards offer a bit more protection and coverage, you have an extra layer of defense against gi burns and abrasions.

That's not to say you can't wear a long sleeve rashguard during nogi training though. Long sleeves can also provide a bit more compression and support for your arms and shoulders, which can help reduce muscle fatigue and improve recovery time after a tough session. And if you train in a colder environment, long sleeves can help keep you warm and comfortable on the mats.

Maintaining High Hygiene Standards

I know we touched on this earlier, but it's important to cover again.

Most reputable BJJ gyms have strict hygiene policies in place, and wearing a rashguard is often a key part of those policies. By wearing a rashguard, you're not just protecting yourself - you're also helping to protect your training partners.

When everyone on the mats is wearing appropriate gear and following good hygiene practices, it creates a safer and healthier training environment for all. Plus, let's be honest - no one wants to roll with the guy who shows up in a ratty old t-shirt that hasn't been washed in weeks. Don't be that guy.


At the end of the day, the best rashguard is the one that makes you feel confident and comfortable. After all, you can't train hard if you're uncomfortable. So go ahead, experiment with both styles, and find the one that works for you. And remember, no matter which one you choose, the real secret to success is the hard work and dedication you put in on the mats.
