Men’s long underwear and base-layer bottoms are perfect for keeping warm no matter the activity. Great for working outdoors, camping or hiking, men’s thermal and long underwear bottoms provide more warmth than their light weight would suggest, and wool men’s base-layer bottoms are warm and breathable, so they work with the body’s heating and cooling system to provide maximum comfort.
