The Castle X Regulator Sock is the kind of layer you appreciate after a few hours in cold boots. Its Merino wool blend helps manage warmth and moisture, while nylon, polyester, and spandex add durability and stretch for riding, working, or knocking around camp. Reinforced cushioning through the toe, sole, and shin adds comfort where boots tend to bite, and the flat toe seam helps cut down on irritation during long days. Made in the USA with a durable knit that holds its shape, this sock fits right into a northern layering setup for snowmobiling, motorcycling, or any chilly job where frozen toes are not on the wish list.
