Your mobile furnace. Just add summit.
This is the insulation you break out when the sun dips, the wind kicks up, or you’re stuck belaying in freezing temps. From synthetic puffies that keep warming when wet to down jackets that deliver serious loft, these layers are made for real mountain cold. Our guides trust them for big climbs and bivies alike — durable, packable, and purpose-built for alpine conditions.
