Over-the-Calf Protection for Extreme Cold and Field Duty
Ideal for Late-Season Hunts, Winter Patrols, and Cold-Weather Operations
When temperatures drop and missions stretch into the night, you need gear that won’t quit. The Wool Beast Heavy OTC Sock is built for endurance in the harshest cold—delivering warmth, durability, and all-day comfort no matter the terrain or temperature. Made with premium U.S. Merino wool, this high-volume sock naturally wicks moisture, resists odor, and helps prevent blisters, keeping your feet dry, warm, and mission-ready.
Dense wool cushioning in high-impact zones absorbs shock and provides relief during long rucks, while compression support keeps the sock secure and stable over the calf. Reinforced with durable synthetic fibers for longevity and a flex-zone instep that prevents bunching, the Wool Beast Heavy OTC is your go-to cold-weather essential for extended field duty.
Content: 70% Natural USA Merino Wool, 8% Wicking Acrylic, 20% Stretch Nylon, 2% Spandex Lycra
