SmartWool Microweight Zip Top - Men's
Throw the SmartWool Microweight 1/4-Zip Top on under your shell before you set out on another dawn patrol. Super-lightweight merino wool keeps you warm without the bulk while managing moisture and fending off odor, and the 1/4 zip lets you dump excess heat when you work up a sweat on the ascent.
