Zip up in cold weather and zip down when it warms up in this year-round favourite, Smartwool's Men's Classic All-Season Merino Base Layer 1/4 Zip. This top uses their All-Season-weight Merino fabric wrapped around a nylon core to increase durability, while still keeping the 100% soft, Merino wool you love next to skin.
