Rashguards are slim fitting, if you prefer a slightly looser rashguard order one size larger than your normal tee shirt size.
A rash guard wicks sweat through its breathable polyester material, helping the sweat evaporate and keeping your body at a cool running temperature. Wearing a rash guard helps you avoid contracting potentially nasty ailments like ringworm and staph infection from mats. Rash guards also help you avoid mat burn on covered areas as they drag against the mat.
