One man’s frozen waste is another’s tundra waiting to be explored. But frostbite? That’s the same no matter who you are – so it’s best to come prepared. Keep biting cold at bay with a midlayer that punches above its weight in warmth. Boar’s Nest Fleece is made with hollow-core polyester yarns that trap insulating air inside each thread. It keeps you as warm as the common, bulky fleece vests but won’t weigh you down. Throw it on when a cold snap rolls into town and charge through the day in total comfort.
