Smartwool Men’s Active 1/4 Zip

If there’s a slight chill outside, the Men’s Active ¼ Zip was made for it. This comfortable, lightweight quarter zip combines the moisture management, temperature regulation, and odor resistance of Merino wool with durability of recycled polyester to help you stay warm without overheating while you work up a sweat. With targeted mesh zones for added breathability, and offset shoulder and side seams to help reduce chafing, it’s the perfect layer for running, jogging, and so much more.
