Thick enough to not be see through but really breathable and stretchy. I’m usually between medium and large (5’5 and 169 lbs) but I went with a medium and they’re perfect. Highly recommend them and I’m usually really picky about tightsThese are nice quality and fit great! I was happy with my purchase. :)Great fitting leggings! Went with my size medium!10/10 would recommend. Wish I could find the same ones but with pockets!! Will be buying more though!Good for the price, material is thin and transparent, not squat proof.I bought these for my lady. She likes wearing them and I like looking at her wear them.Me encantan los leggins con Scrunch quedan super lindos y estos me gustaron mucho los negros nunca deben faltar y yo los amo son buena calidad
