These pants fit really well (I'm 5'7", 140 lbs) and got a Medium. The waist band is soft and doesn't dig in. The fabric itself is very soft and stretchy and breathable. My only complaint is that the slit goes up really high - the pics make it look like it goes up to the knee-ish, bt really it's like button of your butt area. So it's much more revealing that I thought. I intended to wear this out and about in-between pool time, but it's really not for that unless you don't mind such a high slit outside of a pool area. Otherwise these are great.
