These Cozy Winter Warm Socks are made of Merino wool and Angora. Which is the lightest natural fiber known. The hollow structure of its fiber makes it ideal for thermal clothing and has been found to be 8 times warmer than sheep's wool. This added warmth is wonderful for the outdoorsman and sportsman. Here in Minnesota we know the need for that added warmth.We use 80% Merino wool, 15% Angora and 5% nylon in our yarn. By using a high micron count wool, we squelch the rumors of wool being itchy. Also with the addition of 15% Angora it makes a normal wool sock twice as warm. These socks are available in Cream.
