For hiking in low temperatures, UYN has developed the 2IN MERINO socks with high insulation properties. The outer layer is made from Merino Tenwool, an exclusive combination of fine merino wool and Fibresist fiber. The result is a soft, thermoregulating, yet durable fabric. The inner layer is composed of the high-tech fiber Texlyte Nano, which is lightweight and can transport moisture outward, as well as the bio-based fiber Natex. The special two-layer system effectively reduces the risk of blisters while hiking, while three-dimensional structures provide cushioning in strategic areas.
