So, I fell for the hype, and bought a bunch of panties, loved them, then fell for the sales, and bought more $$$$! I only wear them for minor sweat protection, not period leaks, and they do their job for that. HOWEVER, after several months of washing and wearing these, they have stretched out SO MUCH, I can barely wear them. They fall down and roll up inside my pants, and ride up my crack whenever I move around. They flap in the breeze on my coolie. Not a good look for a middle aged woman constantly picking undies out of her butt. I had been wearing cotton and Lycra underwear before this fiasco, and they always held their shape extremely well. I guess I’m out $300 in expensive useless underwear. The idea is great, but they should have done long term studies on these and realized their fabric blend sucks for a very high priced panty.
