Whats the difference between a surfing rashguard and a grappling rashguard?
In general, surfing rashguards are intended to keep your heat in, while grappling rashguards are intended to remove the heat from your body. Surfing rashguards are also made from fabric that feels less synthetic than most rashguards. Keep in mind, though, that a lot of MMA companies are merely slapping their brand name on surfing rashguards.
