Why Wear a BJJ Rashguard? The Ultimate Guide

As a Brazilian Jiu-Jitsu (BJJ) practitioner, you know that grappling can be an intense and sweaty experience. From arm bars to chokeholds, the constant movement and physical contact can leave you feeling exhausted and drenched in sweat. That's where the BJJ rashguard comes in. In this article, we'll explore the reasons why wearing a BJJ rashguard is essential for both training and competition. We'll cover the benefits of rashguards, the different materials available, and some of the best brands to consider.

Why Wear a BJJ Rashguard?

  1. Protection from Mat Burns and Skin Irritation When you're grappling on the mat, your skin can rub against the surface, causing mat burns and skin irritation. Rashguards offer a protective layer that helps reduce friction and prevent these types of injuries.
  2. Hygiene BJJ is a sport that requires close contact with your training partners. Rashguards help prevent the spread of germs and bacteria that can cause skin infections, such as ringworm and staph infections. They also help keep you and your training partners dry and comfortable during training.
  3. Muscle Compression Many BJJ rashguards are designed with compression technology that applies pressure to your muscles, improving blood flow and reducing muscle fatigue. This can enhance your performance during training and competition and help prevent injuries.
  4. Sun Protection If you train outdoors or in a gym with large windows, a rashguard can provide protection from the sun's harmful UV rays. This is especially important if you have sensitive skin or are prone to sunburns.


BJJ rashguards are typically made from synthetic materials such as polyester, spandex, or nylon. These materials are lightweight, moisture-wicking, and quick-drying, making them ideal for grappling. Some rashguards also have antimicrobial properties to prevent odor and bacterial growth.


Q: Do I need to wear a rashguard for BJJ? A: While it's not required, wearing a rashguard can provide several benefits, such as protection from mat burns, hygiene, muscle compression, and sun protection.

Q: What size rashguard should I get? A: Rashguards should fit snugly but not be too tight. Most brands offer sizing charts to help you find the right fit.

Q: Can I wear a regular shirt instead of a rashguard for BJJ? A: While you can wear a regular shirt, it won't provide the same level of protection and performance benefits as a rashguard.


If you're serious about BJJ, wearing a rashguard is a no-brainer. Not only do they provide protection from mat burns and skin irritation, but they also help prevent the spread of germs and bacteria, improve muscle compression and provide sun protection. With the range of materials and top brands available, there's a rashguard out there to suit every BJJ practitioner's needs. So, why not invest in one today and see the benefits for yourself?
