A great companion for ski tourists, trail runners, and other serious outdoor athletes, the Mammut Rime IN Hybrid Flex Jacket combines Ajungilak® stretch insulation with a durable Pertex® Quantum Air shell to create a very water resistant garment that still breathes like crazy. On its own when you're working like a dog or under a shell when you're descending or the weather takes a nasty turn, the Rime Hybrid will make itself indispensable in short order.
