With Art Socks, you have to go into the description to see the sock material content; it varies from pattern to pattern. These are only 46% cotton. Other styles are over 54%. I try to avoid nylon/polyester in socks because it wears out quicker in the laundry and also makes my feet stink. Of all the socks I've ordered from Art Socks, I like this pair the least. The colors (kelly green, red, bright sky blue) are wrong for Klimt, whose works veered towards lots of gold and oranges. I bought these because they were on sale and now I see why. Disappointed in the material blend and the color.
