Comfort and functionality can make a big difference in your workouts. Make sure each is addressed with the right workout shorts. The Interval shorts address that and much more. They are made with four-way starch for range of motion, an ultra-wicking shell for mobility, and a no-pinch, no-bunch waistband to maximize comfort. Each pair also has a pocket system to keep your phone and keys secure and a medium compression liner with permanent silver ion anti-odor treatment.
