Comfortable and cozy against the skin, the Mammut Men's Eiswand Light Zip Pullover is an ideal baselayer, trapping heat with its Polartec Power Dry fabric. The shirt's fabric wicks moisture, preventing you from feeling cold and clammy when you're outside in the elements for hours on end. Wear this as a standalone piece on chilly autumn and spring days, or rock this underneath a shell for extra warmth on frigid days. The shirt's half zip design allows you to cool down quickly, and the high collar blocks harmful rays from burning your neck. Flat lock seams won't irritate your skin, and the zippered Napoleon pocket stashes light snacks and small accessories.
