Cold feet can sideline even the most steadfast hunters. Complete your late-season system with the Heavy Weight OTC Sock and stay focused in the field through the coldest snaps. Temperature-regulating merino wool is woven with advanced PrimaLoft® yarns to lock in heat, and it’s reinforced with Cordura® at the heel and toe to reduce the strain of demanding pursuits. Performance zones throughout the sock provide a low-bulk fit inside boots without sacrificing warmth or cushioning, giving you comfort for miles.
