Our Adirondack Wool half zip is the perfect addition to your winter running gear. Made of a soft and light weight composite of 80% merino wool, 20% poly, the Adirondack is breathable and wicking on its own and a cozy base layer when the temperatures drop. Thumb holes will keep sleeves in place under a jacket or gloves, and the half-zip mock-turtleneck allows you to dial the warmth up or down.
Fabric: 80% merino wool / 20% polyester
