Rashguards are an essential form of protection from what is commonly known as “mat-burn”, or damage caused to the skin from contact with the traditional tatami mats used in jiu jitsu. As these mats feature a textured surface which renders them waterproof whilst also offering traction, friction between skin and mat can result in this type of burn. Although the soles of the feet and palms must remain uncovered during combat, the preventative measure of wearing a rash guard can protect key areas of the body such as the chest, arms and back. Consequently, a long-lasting, hard-wearing rashguard is an essential item for anybody looking to become involved with Brazilian Jiu Jitsu, and at RockyGears we have you covered, with our extensive selection of mens rash guard long sleeve and short sleeve shirts
