The Marmot Men's Essence Jacket offers reliable waterproofing in a lightweight and highly compressible package for alpinists, backpackers, and trail runners. Marmot's NanoPro MemBrain equips the Essence with waterproofing that stays highly breathable for intense activities, and the 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 full range of motion, too, so you can run, hike, and climb without feeling restricted. 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.
