What Our Gearhead(R) Experts Are Saying:"I packed this vest for a hut trip and was impressed by how much warmth it gave for how little space it took up. The 800-fill ProDown is super lofty, and it held up to light snow thanks to the water-repellent finish. It's ideal for high-output cold weather activity or a lightweight layering piece."When we're counting grams and dialing layers, the Summit Breithorn Vest from The North Face is a piece we always make room for. Designed for demanding alpine conditions, this ultralight midlayer brings the heat with responsibly sourced 800-fill ProDown(TM) insulation, all packed into a slim, technical profile that punches way above its weight. The outer shell features Pertex(R) Y Fuse technology, increasing durability and downproofing while enhancing water resistance. A non-PFC DWR treatment sheds moisture during snow-covered approaches or fast-moving ridge pushes. The vest stows neatly into its own hand pocket, making it the ultimate bring-it-just-in-case layer for summit bids, ski tours, or cold-weather climbs. Thoughtful touches like the internal hem cinch, insulated draft flap, and internal drop-in pockets make it a true alpine specialist. Built for the Summit Series(TM), it's made with 100% recycled nylon and designed to meet the demands of technical mountain travel.
