Our men’s butter tech fleece is a play-hard pullover that’s made to move. Part of olympian sage kotsenburg’s backcountry collection, every aspect was designed with full days and nights in mind: cordura nylon panels at the neck, shoulders, and elbows boost durability, while overlock stitching give it stronger seams. A zip-closure kangaroo pocket lets you warm hands and stash mitts (and more), while elastic binding on the cuffs and hem help keep warmth in – and cold air out. Use as a midlayer on colder days – or on its own for the big climb up, and long run down.
