The ingenious design wicks away excess heat when you're on the go, but retains it during downtime. Polartec Alpha Active insulation is made up of a polyester mesh lining and a highly breathable nylon shell that makes Outdoor Researche's UberLayer a backcountry chameleon. It provides the warmth of an instant synthetic puff, plus the breathability and quick-drying performance of a synthetic, all without forcing you to add, remove, or adjust your layers.
