Built for long days in the tree stand or ice fishing on the lake. At 78% Merino Wool this is the warmest sock Hiwassee makes, and Merino's natural anti-odor property means the sock won't give your scent away. Over-the-calf height won't fall down in tall or loose-calf boots, and reinforced high-wear zones handle the mileage. Ultra-soft next to skin. Olive Green or Blaze Orange. Made in Niota, Tennessee.
