Cold feet can sideline even the most steadfast hunters. That’s why it’s important to complete any late-season clothing system with the Heavy Weight Crew Sock from Sitka 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. Built-in performance zones throughout the sock provide a low-bulk fit inside boots without sacrificing warmth or cushioning, and an anti-twist band in the mid-foot keeps the sock in place to reduce bunching, providing all-day comfort.
