Customer feedback

Comments: Very comfortable! I wore these for the first time this week. It was 20 degrees out and these tights are a little thicker than I would normally wear for the temperature. I usually get too hot when wearing tights. They were incredibly comfortable, allowed plenty of freedom of movement and were warm enough without being too warm for me. I could have worn them all day!
