The Smartwool Men's Classic Thermal Merino Base Layer 3/4 Bottom is a warm 100% merino tight cut to 3/4 length. It keeps ski boots, hiking boots and running shoes free of extra bulk and friction, and the redesigned fit cuts down on sag.
Thermal merino is about as warm as base layers get, and the 3/4 length keeps your boot fit clean.
Skiing, winter hiking and cold weather layering. Built for cold mornings on the lifts at Monarch Mountain.
