These pants are super comfortable! The fabric is nice and soft. I would prefer it to be a bit thicker, but is isn't thin- just not as thick as cotton sweatpants. The sizing guide for these pants will have you buy too large. I have a 30" waist and 38" hips, 5'10", 150 lb. I believe the guide suggested buying a large (which I never buy). I went with medium, which were too big and had to exchange for small, which fits perfectly.
