I bought this tights as a gift for my girl. First i ordered a small since that was what the size chart recommended but she was much better in a medium. This are great tights, a little tighter that other brands so i recomend to size up. She loves it and i am really happy with Backcountry.com, they made the exchage, shipping very easy and extremely fast. I recommend Backcountry.com to anyone, im a happy costumer and i will keep coming back for more gear.
