What is a rash guard for BJJ?

If you are new to Brazilian Jiu-Jitsu you may have heard other practitioners talking about rash guards. But, what exactly is a rash guard, and do you need one to practice BJJ?

A rash guard is a tight-fitting top that is typically made of a combination of polyester and spandex. Rash guards are made to fit tightly on the wearer's body with moisture-wicking materials that allow heat to disperse from the body with ease. 

Many practitioners wear rash guards underneath a gi or as a stand-alone garment. During some BJJ tournaments, Nogi practitioners may be asked to wear a rash guard that represents the belt they are currently ranked in. 

Finally, do you need a rash guard to practice BJJ? Most gym's will require that the practitioner's wear BJJ rash guards for safety reasons. This is because a person is more likely to get a finger or other body part caught on a loose article of clothing. That could have some serious consequences such as a strained or broken finger.
