Made with durable wool in an uncommonly tight weave that turns away wind while remaining highly breathable. Wool's complex natural structure wicks moisture to the tip of each fiber, enabling it to insulate dry or wet. It's wet-weather performance is the reason wool has been the fabric of choice for outdoor protection for centuries. With four flapped pockets on the front and a full-width pocket the entire back, two layers of wool protect most of the torso, right where it's most needed.
