If you're looking for a do-it-all jacket for your mountaineering endeavors, then the Mammut Rime IN Flex Hooded Jacket just may be the thing for you. Finding the balance between a hardshell and an insulating layer, this jacket features stretchy and lightweight Pertex Quantum Air fabric for highly breathable comfort and water-repellent protection, making this a perfect outer layer for times when you're not expecting stormy weather. Stormy weather often comes even when you're not expecting it, and when it does you'll be able to throw a shell on and layer up with the toasty warmth of the OTI stretch insulation. This synthetic insulation offers warm-when-wet performance, and will move with you for non-restrictive warmth up the mountain. The insulated hood fits over an alpine helmet for warmth and coverage when alpine winds are whipping, and the front pockets are easy to reach when wearing a harness or backpack.
