No one's ever been in the middle of a high-altitude trek and wished they felt colder and more restricted. Movement is paramount when exploring technical terrain, and thanks to the Mammut Rime IN Hybrid Flex Jacket you'll have all the mobility and easy-layering warmth that you need for your demanding cold-weather pursuits. It's built with lightweight Pertex Quantum Air fabric, which resists water, lets you move freely, and offers breathable comfort during activity. On the inside, Toray Stretch insulation provides comfortable warmth without the bulk, ensuring that this jacket can slide easily under layers and won't limit your movement when you're reaching for a hold or scrambling towards the summit. Elastic cuffs and an adjustable hem keep out the cold without adding weight, while backpack and harness compatible pockets ensure that gear and snacks are always within reach.
