Excellent versatility and lightweight and durable material are the key ingredients of the ideal softshell jacket for a wide range of activities in the mountains. We've made the Air LT Hoody Jkt from a specially woven Nylon+Polyester material with a blend of elastic fibers and a durable water repellent treatment, thus achieving strength, lightweight, wind resistance, and high breathability. The textured reverse side of the material adds subtle insulation to the jacket, while also wicking away moisture excellently during active movement in cold weather. The hood is also adapted for use with a helmet, so you can just put it on and go. You can keep your hands warm in the large zippered side pockets, and you can playfully stash your essentials in the inside pocket and sleeve pocket. Tighten the bottom drawcord and the heat generated by you has no chance to escape.
