i just got them so i can't vouch for how well they'll stay together, but they are SOOOO comfortable, a really nice microfiber microfleece kind of material is inside that is so soft! so the legging is super thick and warm.i'm 5'2 and 115 pounds and i can never find leggings that fit well - they're always too long - but these come up to just above my ankle.
i'll be getting another color soon!
