I love these leggings! I have to buy another pair, 'cause I don't want to wear anything else. I live in New Mexico where winter days can be in the upper 50's to 60's and strong sun, or cold with high winds. In either case, I stayed comfortable. They fit great, look great, and feel so soft. I've washed them twice and they look new. I am 5'6, weigh 130 pounds, a medium was just right.
