Created in collaboration with trail athletes, the Flight Series™ collection makes you tougher and stronger. The Stridelight Shorts are breathable, and when the summer heat makes you sweat more, the perforations in certain ventilation areas will help you stay cool. Quick-drying FlashDry™ technology also wicks away sweat. The lining of the briefs is comfortable, while the pockets at the waist allow you to store your phone, keys or gels.
