For your next trek up winding trails, big walls, or high-altitude peaks, pack along the Klattermusen Atle 2. 0 Jacket. Versatile enough to not be out of place in your everyday life, but high-performing enough to help you thrive in extreme conditions, this jacket is a reliable option for anyone looking to level up their puffy game. It's filled with toasty warm 800-fill down insulation, which packs easily into a pack or travel bag, and layers well under a shell thanks to the jacket's slimmer fit. It's also got plenty of features to help cut back on stress and help you stay focused on the task at hand. The 3D adjustable hood is easy to operate with mittens or gloves on, and follows the head without obscuring vision. Down-filled storm flaps over the main and pocket zippers prevent snow and ice buildup, while raglan style sleeves enhanced your movement as you work through tricky ice-climbing routes. And you don't have to worry about durability concerns when carrying a pack thanks to the reinforced shoulders, which also boost this jacket's water-resistant properties when you're out in snowy weather.
