A short length run short with super light Vapor fabric to keep the wearer feeling fast, comfortable, and dry. Internal lining for ventilation, reflective prints and invisible side pocket make these shorts a high performance training companion. Unique Vapor fabric features micro-filament polyester yarn with hydrophobic properties for supreme comfort in a 'zero cling' fit. A lower denier ( finer ) yarn on the outside wicks moisture from the higher denier ( thicker ) yarn on the inside for exceptional moisture management.
