This is my first time buying sweats from here and the quality did not disappoint! I love that the material is the exact same as the crewnecks and hoodies!! Super and soft and thick, and will definitely keep you warm. I also like how there's an adjustable drawstring on the inside! I'm 5'4, 135 lbs and I got a size large. It fits perfectly around the waist and looser around the legs. I think I could have gotten a medium and it would have fit just as well, but I like the slightly oversized fit!
