When winter settles in and long sits turn into tests of endurance, warmth starts from the ground up. The Sitka Heavy Weight OTC Sock is designed for hunters who push through the coldest conditions, delivering full over-the-calf coverage, reliable insulation, and long-lasting comfort. Built to complete a cold-weather system, it keeps warmth locked in while maintaining the breathability needed for all-day performance.
A merino wool blend naturally regulates temperature and manages moisture, keeping feet warm even when conditions turn wet or unpredictable. PrimaLoft® yarn technology enhances heat retention without adding unnecessary bulk, allowing the sock to fit comfortably inside insulated boots while maintaining airflow. The result is dependable warmth that adapts to movement and changing temperatures throughout the day.
Reinforced with Cordura® in high-wear zones, the Heavy Weight OTC Sock stands up to demanding terrain and extended use. Strategic cushioning and performance-mapped knit zones provide support where needed while preventing excess compression inside boots. The over-the-calf design adds coverage and helps keep the sock securely positioned, while an anti-twist midfoot band reduces bunching and friction during long miles in the field.
