The Marmot Men's Essence Jacket offers reliable waterproofing in a super light and highly compressible shell for alpinists, backpackers, and trail runners. Marmot's NanoPro MemBrain equips the Essence with waterproofing that stays highly breathable for intense activities, and fully taped seams enhance waterproofing by preventing rain and snow from seeping through. The jacket's athletic fit includes Marmot's Angel Wing Movement for a full range of motion. Integrated cooling vents keep you comfy when you work up a sweat, and the moldable brim keeps the hood out of sight and conforms when stuffed in your backpack. The Essence also has 360 degree reflectivity to help keep you visible on early morning ascents.
