Over forty years ago Terramar was the first company to introduce silk performance base layer products. Thermasilk is still going strong. The Thermasilk Mid Calf Sock Liner offers a natural super soft touch and feel with all the technology you need. The result is a breathable lightweight sock liner that keeps you warm, dry and comfortable for all your outdoor adventures. The tradition continues.
