The "super leakproof thong" is anything but - I own 3 types of period panties and this is the only one I have regretted purchasing. The placement of the pad is too high, and the thong is too narrow, so I'm constantly leaking. These are better off in the garbage. I ordered 3 other products from Knix, all which had to be returned do to poor fit. The return process was easy, but the lady I emailed with wanted me to wash and wear the items up to 3 times to see if the fit improves - which is a terrible business model, who would want to keep items in the hopes they fit after washing and thus not being able to return them?!
