The Norrona Lyngen Down750 Mitten is built to live in a pack, not on your hands all day. Recycled ripstop nylon wraps 750 fill power down for real warmth that packs down small enough to disappear into a jacket pocket or backpack. A leather-reinforced palm and thumb hold up to the abuse of pulling skins or gripping poles once conditions force a swap from gloves to mittens. What Our Gearhead(R) Experts Are Saying:"My gloves handled the climb fine until the wind picked up above treeline, and that's when these came out of my pack. The down warmed my hands back up faster than I expected for something this packable."
