Give your hardworking legs a break with the Marmot Men's Thermalclime Pro Boot Tight. This baselayer features Polartec Power Dry fabric to wick moisture and dry up quick whether you're climbing a mountain or skiing down it. An athletic fit pulls this tight to your legs for easy layering, and the calf length reduces bulk in your boots. Even though the fabric is naturally stretchy, Marmot added a gusseted crotch for an even better freedom of movement. And flatlock seams keep your legs comfy from the bottom of the mountain all the way to the top, or vice versa.
