Extend your comfort zone on the trail by pushing hard, then let the 50K Shorts do the rest. Simple, streamlined and made for the serious runner, the shorts' durable 100% polyester plain weave fabric feels soft against the skin, and the built in liner's polyester crepe fabric wicks moisture and won't chafe. The lightweight jersey waistband is wide and comfortable with a drawcord that lies flat, and two front pockets, built into the waistband to keep contents stable, lie flat when empty. The external envelope pocket at the center back features a key loop. A reflective logo at the left hem keeps you visible. Inseam is 4 14.
