Soft Merino wool naturally helps regulate body temperature, manage moisture and resist odors, making it a dependable first layer for skiing, hiking and other winter adventures.
The slim fit layers comfortably under jackets and midlayers, while the quarter-zip neckline lets you quickly vent excess heat when your activity level picks up.
