When the mercury is riding low in the gauge, you want a base layer that is warm and ultra comfy next to your skin, especially when you're wearing it all day. The Columbia Men's Baselayer Heavyweight Tight w/ Fly is made from polyester fabric with little reflective silver Omni-Heat dots printed in zones that need heat the most.

From skiing in Colorado to trail running in Alaska, the Columbia Baselayer Heavyweight Bottoms for men will help you keep the heat and lose the sweat.
