It may be the fabric but the legs are too tight and the waist constantly falls down. Can't take these to the gym! Now I have 3 pairs that I can't wear!

The fabric is very soft and smooth, and the fit is decent, however, there is no compression whatsoever and the waist band does not stay up. Constantly tugging them up. Would not recommend for working out.

This was a great first pair of leggings. They had always intimidated me. They are comfortable and look great. I got a medium and probably should have gotten a small. I will definitely purchase again.

I liked them and they fit until I ran in them. Constantly sliding down. I got creative and put a drawstring in them. With a drawstring they are perfect. I may put a drawstring in all my leggings! Love the royal Blue color! Love the pockets!

Other than one pair of leggings that I've gotten from RBX (fits weird in the crotch, ha) I've loved them! This one is so soft, not too tight and is perfectly high waisted.

Good price, good compression but waist has awkward fit and they seem to want to Slip down in the crotch area so your still pulling them up too much for me.

I am happy with the fit and comfort of these leggings. They provide nice compression without feeling too tight. I like the high waist and the pockets.

These may be the perfect leggings. Everything about them is awesome. Conveniently located pockets, waistband that doesn't roll, thick fabric that doesn't sag or bag anywhere even after wearing for hours... Excellent quality.

I absolutely love these Flex leggings! As a petite woman, they fit me perfectly with just the right amount of flex and the perfect length. Also love the side pockets!

They really don't stay up. It absolutely has no hold at the waist. The only two good thing about them is pockets and the material feels great I wish they had a better hold at the waist they would be perfect other then that.
