These leggings are different from any others I have. The fabric seems to be made of super fine material, like you can’t see the threads it’s woven from. This makes it very thin, though not see through and all and highly compressive. I ordered in my size and actually returned (very easy process!) for size larger as it felt like they were too tight in the legs which could cause them to pull down during workout. Part of that feeling comes from the cut of the waistband in the back - it dips down so that it starts over my crack (sorry) and makes it feel like the leggings aren’t covering my not-very-big butt when in fact they are. Not wild about that feature but otherwise they perform like a dream, breathable, wicking, move with you through high intensity. Wish they had a key pocket for running. Great colors and different gusset mean maybe the only no-camel toe leggings! Good job BP.
