The Men's Patagonia Strider Pro Short features a quick-drying fabric made from 90% recycled polyester and 10% spandex, woven with four-way stretch to ensure ease of movement and a comfortable fit while shedding light moisture thanks to a durable water repellent finish. The lightweight elastic waistband provides excellent power and recovery, moisture management, and reduced bulk, while an external drawcord allows for adjustable comfort. Four stretchy envelope pockets provide storage for essentials, and a secure zippered pocket at the center back includes a key loop for valuables. This short comes with comfortable liner briefs and includes a locker loop for hang drying.
