I did not understand what I bought. They were all supposed to be wool, but it turned out to be a blend of wool, cotton, polyester and rayon. It was very disappointing as were the colors. They sent me all black and shades of black. I was really hoping for some color and they are ribbed around the arch which is both a good and bad thing. Since I only wear them indoors, I'm calling it bad, but a lot of people might like it. Overall they are very warm and I would probably give them five stars if the description on the internet was more accurate and I received some colors as stated in the description.
