We're pleased to bring you one of Mountain Hardwear's most popular jackets, now officially part of UM merch. Known for its comfort and warmth, the Mountain Hardwear Monkey Man™ jacket is made from Polartec® High Loft™ fleece. Strategically-zoned side panels maximize stretch and breathability where you need it most; they also wick moisture away and make the jacket easier to pack when hitting the road.
