OUT OF STOCK
Our single-layer polypropylene thermal long underwear top is uniquely engineered to keep you warm and dry during outdoor activities such as hunting, fishing, skiing and running. Because the extraordinary wicking ability of this polypropylene fabric draws moisture away from your skin, you stay warmer and dryer than with cotton thermals. It's also perfect for layering under other clothes for extra warmth. This thermal top is in navy blue. Please see our matching bottoms and alternate colors as well.
