Bought these new. Put them in my sons drawer. He never wore them. So these are actually new. One pair of the pants has a hole in it. See pic. Must’ve gotten snagged on something in his drawer. I have washed and dried them to freshen them up. Both pairs are identical. Size XL 18-20. Designed to adapt to your temperature and activity. X-temp speeds and slows cooling to keep you comfortable all day. Soft waffle knit thermal fabric. 60% cotton 40% polyester
