Lighter than your last breath and more rugged than an armored bear, the Marmot Artemis Men's Jacket is the last word in breathable, versatile shells. Built with Marmot's new 2. 5 layer NanoPro MemBrain laminate, the Artemis boasts a ridiculous 47K breathability rating, along with underarm zips, so you'll never have to worry about sweat building up and turning things soggy from the inside out. It's also completely waterproof, with fully taped seams and a helmet compatible Gale Force hood to keep the storm at bay. Like any good climbing or backpacking shell, it has pack and harness compatible pockets, and uses Marmot's Angel Wing design to ensure that you'll be able to hike, backpack, clip bolts, and plug gear with full freedom of movement.
