Smartwool Men's Classic Thermal Merino Base Layer Crew

With new patterns, a fresh look, and even more comfort, our Men's Classic Thermal Merino Base Layer Crew is being its best self. We've 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 minimize chafing. Add one of our best base layers for cold weather to your winter wardrobe and experience the difference the next time you go skiing, hiking, climbing, or biking.
