These are my favorite CRZ yoga leggings that I've tried. These stay up during CrossFit, which is awesome, with all the running, jumping, and high intensity that we do, it's hard to find a legging that doesn't fall down constantly. I don't have to pull the waist or scrunch the legs up or mess with them at all during my workouts. On top of that, they are more sweat wicking than my other CRZ's and overall, just better quality. I'm 5'7, 160 lb, muscular and fit and I ordered a Medium and they fit perfectly. Super comfortable and soft. I have a TON of leggings, both luxury brand and Amazon affordables. These ones I will be ordering again, hope they get lots of new and unique colors as currently the selection is small.
