Very gently worn set. Thin and perfect for layering in cold weather. It doesn't really get cold enough where I live for me to get much use out of the set. I have washed them on cold in the delicate cycle and hung them to dry with no problems. They are 100% Merino wool. They fit like an XS. These are from a smoke free, pet friendly home. I will lint roll them before shipping but please note that I do have two dogs.
