Very thick. Would be great for winter leggings. I believe these run very tight.
These are great quality leggings. Thick, squat proof, super cute and best of all they are super flattering and tuck it all in! I’m 5’4” and I wish these were about an inch shorter, but I love them so much I don’t care that they are a tiny bit longer than I prefer for leggings. I wear size 5/7 jeans and got the medium.
