They're great - I live in snow-country so they're so seriously the perfect option. Will be buying more!
I've only just tried these on and they feel wonderful. Lightweight and sexy. Full butt coverage and normal waistline. I normally wear a medium but need a large in some brands. I decided to try a large as I did not want to be confined to something too tight. I made the right decision. My waist is 32- 33 inches. I can't wait for cold weather to try them out under my pants. I think they will be very comfortable and less restricting than full length underwear or base layers.
