Waterproof, breathable, and stylish, the Burton AK 2L Embark Gore-Tex Jacket is a durable piece of winter armor with a Gore-Tex (duh) construction and lightweight insulation to keep you warm and dry through some of the mountain's nastier weather. The waterproof breathable two-layer Gore-Tex fabric blocks out wind, snow, and rain while allowing vapor to escape so you don't get drenched with sweat on the inside, and fully taped seams with Gore-Seam tape prevent moisture from seeping in through the cracks. Lightweight and low-profile Primaloft Silver insulation keeps you warm without weighing you down or restricting movement. It also has a buttery-soft down-proof lining that provides a soft feel and helps the jacket slide on effortlessly. The AK fit features engineered articulation to allow for total freedom of movement, and it allows room to layer underneath without being baggy or bulky. Zippered underarm vents let you dump heat when you're hiking to the peak, and the contoured hood with a micro-adjust cinch shields your head when an unexpected storm suddenly rolls in. A removable stretch powder skirt with jacket-to-pant interface keeps the snow out on waist-deep days.
