Great quality shorts, but definitely size up! I am 5’6” 132 lbs, lean/athletic build, and can usually wear a small or medium in CRZ yoga pants and running shorts. I purchased a medium in these after reading other reviews suggesting to size up. I should have purchased a large. The return/exchange policy isn’t worth the hassle and additional cost, so I’m going to give them to my 13 year old extra small niece.
