I read a post about these new kind of diapers either on here or on DailyDiapers. But it was a brand sold in the 99 cent store. They come one diaper per pack. They say on the page they are adult "underwear". But if you look at the picture on it, it shows tapes. And once brought home, they are indeed diapers, not pull-ups. I wasn't expecting much from a 99 cent store diaper, but I was quite surprised. I found them to hold a LOT. On par with a Wellness Briefs which shocked me. And they swell quite a bit. I wore it for my nap and only expected a few hours. I ended up sleeping for 6 hours (guess I was more tired than I thought) and the diaper held every drop with room to spare. They only had 3 diapers on stock in my size at the time, but I will keep checking back. I recommend anyone with cash to spare to buy a few to try. But they are not found in the baby isle. They are found in the health care isle with the female pads and the like. Enjoy.
