Im writing as a first impression bc im torn to keep it or not. The material is significantly flimsier than the optime leggings I own. Looking at it- these are only 15% spandex vs the OG being 27% spandex. Which is likely why they feel so thin and flimsy and like they could start sliding (not rolling) down— which would be a problem in any case, but esp as I got these for strength training, not a lower impact exercise. And, that’s what they claim they’re best for (training). I bought my size, and though they might be a tad bigger, it’s not enough to size down, so it’s not a sizing issue. It’s more a quality issue. So… for those reasons I might return. I bought them for the function, but also the color and style, which I do like. Not enough flared leggings in the market right now, imo.
