Named for the Yukon—Canada's westernmost territory and a picturesque mountain range featuring five peaks over 15,000 feet—this heavyweight crew is designed to be one of the warmest layering tops you'll find. The 400 g/m² construction keeps body heat in while the fine 18.5-micron 100% Australian merino wool rapidly wicks moisture during high activity and prevents heat loss when you're standing still. Whether you're wielding an ice axe on a near-vertical ice sheet or taking the dog for a walk on a cold afternoon, this garment will perform to your satisfaction.
