Meet the better-than-ever men's Classic Thermal Merino Base Layer Crew. Smartwool has updated this 100% Merino wool fan-favorite with new colors and a new fit to improve functionality while enhancing aesthetics. Shoulder panels eliminate top shoulder seams and a flatlock seam construction helps prevent chafing. Add one of Smartwool's best base layers for cold weather to your winter wardrobe and experience the difference the next time you go skiing, hiking, climbing, or biking.
Formerly known as the Merino 250 Base Layer Crew. Packaging may have either name but the product is identical.
