Who Needs Rash Guards?
BJJ Warriors: BJJ warriors absolutely need BJJ rash guards. They are essential for protecting the skin from mat burn and gi burn during rolls. The compression fit also supports muscles and prevents your opponent from getting a easy grip on your body.
MMA Fighters: For the modern MMA athlete, the rash guard is non-negotiable armor. It is your primary defense against the abrasive grind of the gym mats, shielding your skin from friction, bacteria, and mat burn. This isn’t mere apparel; it’s a tactical layer that manages moisture and denies your opponents easy control, turning your defense into an advantage.
Muay Thai Clinch Artists: Embrace the grind. Muay Thai demands a rash guard to shield the core from the relentless friction of training. This isn’t apparel; it’s essential equipment that supports muscle integrity and allows you to drill with absolute focus and power.
Wrestlers: For wrestlers, a rash guard is mandatory equipment. It is a second skin designed for the grueling reality of the mat, providing crucial defense against mat burn. The compression fit supports muscle endurance for explosive shots and scrambles, while wicking moisture to maintain peak performance through every round.

A rash guard is a tight-fitting athletic top designed to protect the skin from friction, mat burns, and cuts during sports like Brazilian Jiu-Jitsu, MMA, and wrestling. It also helps regulate body temperature and wicks away sweat during training.
Should a rash guard fit tight or loose?
Rash guards should fit tight, like a second skin. A snug fit ensures they stay in place during rolling or striking and prevent fabric from getting caught or pulled. A proper fit also enhances compression and moisture management.
Why do they call them rash guards?
The term comes from their original use in surfing, where the garment was designed to 'guard' the skin against rashes caused by friction from the board or salt water. The name stuck as they became popular in other sports like BJJ and MMA.
Are rash guards just compression shirts?
Not exactly. While they look similar, rash guards are made with stronger stitching and more durable fabric blends to withstand intense contact and friction—especially during grappling. Compression shirts may not hold up in combat sports.
Do you wear a bra with a rash guard?
Yes, many women choose to wear a sports bra under a rash guard for added support—especially during high-intensity training or sparring. Rash guards are typically unpadded and compressive, so a sports bra helps with comfort and security while rolling or striking.
What do you wear underneath a rash guard?
Most people don’t wear anything underneath a rash guard, as it’s designed to be worn directly on the skin. However, some women may wear a sports bra or compression top underneath for added support.
What are the IBBJF rules for rashguards?
For IBJJF competitions, rash guards must be form-fitting and reflect the athlete's belt rank in colour. In no-gi divisions, at least 10% of the rash guard must show the athlete's rank colour (e.g. blue, purple). Team logos and sponsors are allowed, but loose-fitting tops are not permitted.
Are rash guards necessary for BJJ or MMA?
es, rash guards are highly recommended for both BJJ and MMA. They help reduce skin-to-skin contact, minimise the risk of infections, and improve hygiene. They also compress the muscles and stay in place during grappling or striking.
Can I wear a rash guard for gym workouts?
Absolutely. Rash guards are great for gym sessions thanks to their moisture-wicking fabric, breathability, and muscle-supporting fit. They work well for strength training, cardio, or even as a base layer under other gym wear.
