In a sport like grappling, bjj rash guards move around and engage in physical contact, so it’s important to keep the skin protected. Rash guards are made of smooth fabrics that reduce friction with the mat and shield the athlete from cuts, scrapes, rashes, and infections such as ringworms and staph.

High quality rash guards are usually made from a mix of polyester and spandex (commonly called lycra). They are designed to fit tight to the body and offer moisture-wicking properties, keeping the athlete cool, dry, and comfortable. They also regulate the body temperature, preventing heat from building up on the surface of the skin.
