Smartwool Men's Classic All-Season Merino Base Layer 1/4 Zip Color:Black above tree-line and anywhere inWe took our popular Merino 150 Base layer and added a 1 4 zip to itmaking it the perfect base layer for warm or cold weather. This top uses our lightest weight Merino fabric wrapped around a nylon core to increase durability, while still keeping the 100% soft, Merino wool you love next to skin. Side seams help minimize chafing while wearing a pack and offer a body enhancing fit. Select colorways feature a more responsible plant based dye technique.
