The 7" Strider Pros blend enhanced protection and coverage with additional storage for the long haul. The polyester crepe liner (now a regular brief profile, with Polygiene® permanent odor control) wicks, adds chafe-free comfort and is light, fast drying and highly breathable. Four overlapping, stretchy back hip pockets (two on each side) carry what you need for a full day of mountain running; an additional stretchy, card-sized center-back pocket closes securely with a zipper. We’ve moved to a lighter, faster-drying 100% recycled polyester stretch ripstop fabric on the outer body, with generous side splits to further enhance airflow. With a reflective logo on the left hem, a locker loop for hang drying and a DWR (durable water repellent) finish.
