It's hard to beat a pair of split running shorts for breathability, freedom of motion, and comfort. Brooks took this simple idea to the next level by incorporating plenty of storage pockets into their Sherpa Split Shorts. The additional pockets around the waist make extra room for gels, a bar, and a phone, so you can leave your running belt or vest in the car and enjoy your trail run unencumbered. An integrated key retainer loop keeps your car keys secure. Plus, the mesh pockets sit flat when empty, so they disappear when you don't need them. Features a stretchy, sweat-wicking brief liner.
