These stretchy REI Co-op hiking pants deliver fast-and-light performance with a relaxed fit for unrestricted movement. The lightweight, 4-way stretch nylon/spandex fabric breathes well, dries quickly and features a durable water repellent made without PFAS to help moisture bead up on the surface.
Built for the trail, they offer UPF 50+ sun protection and a low-profile pull-on waistband with internal drawcord that sits comfortably under a pack hipbelt. Roomy hand pockets include an internal stow pocket, while a zippered thigh pocket keeps essentials accessible even with a hipbelt. A crotch gusset and breathable Swiftland Grid waistband provide venting and moisture management, and the internal cinch at the cuffs lets you adjust the look or seal out weather and bugs.

Tested and loved by REI staff. “I bought these for lightweight sun protection and they've become a year-round hiking staple. On a 6-day High Sierra Trail trip, they worked equally well as my hiking pants during the day and my camp pants at night.” — Hal, REI Staff - California, Hiking since 2000
