Our most durable and technical leggings made from our renowned lightweight, weather-resistant soft shell fabric, the Ferrosi Leggings use engineered stretch that’s snug to get on and stays in place for rugged pursuits, featuring multiple side pockets and Cordura® panels at the knees and seat for added toughness.
For those of us who do everything in leggings: Hiking, climbing, backpacking, and wherever else the trail takes us. The Ferrosi Leggings are our most durable and technical leggings made from the ever-popular Ferrosi fabric, which means that they use the the same durable, super stretchy, incredibly breathable, and undeniably comfortable soft shell performance that the matching jackets offer. Now, new and improved Ferrosi fabric is 46% recycled with improved stretch throughout. These leggings are enhanced with extra durability at the knees and seat with Cordura® panels, complete with a drawcord to adjust the waist on-the-go, and finished off with drop-in pockets for larger items like your phone, and a smaller zip pocket for valuables like your keys. A high waist means you can wear your harness or buckle your backpack belt tight without worrying about uncomfortable rubbing, sliding, or moving around.

It hits the equilibrium of being durable yet lightweight, it’s weather resistant yet breathable, and it’s complete with stretchy, easy-to-layer comfort. The Ferrosi line grows season after season, but is most frequently favorited by climbers and hikers for its jackets, hoodies, pants, and shorts. Ferrosi is truly the “do-it-all” choice for any adventurer looking for a layer that ticks three or more items off the gear list.
