The Under Armour UA Velociti Elite Men's Shorts are made of lightweight stretch fabric that is durable and moves with you. The back is made of ultra-breathable Airvent material with a ripstop finish for maximum ventilation. The material wicks sweat and dries quickly. The inner mesh lining provides additional coverage and support. The shorts have an elastic waistband with an internal drawstring, a secure back zip pocket and external pockets with an elastic key loop. Anti-odor technology minimizes odor.
