Best short EVER

I absolutely love these shorts!! Zero ride up, even slept in them they were so comfy. Absorbed all the sweat and spotting I had with zero problem. Even if they weren’t leak proof, the fit is so spectacular that I want 10 more pairs. Bought size M, 5’ 6”, 135 lbs with thighs that have touched my whole life

LOVE THESE!

I was sceptical about these thinking they'd be hot and roll down. They are neither! They're thin, super comfortable, and didn't roll at all, I'm going to be ordering more as I could live daily in these. Worth every penny of asking price!
