They could stretch a little more, but if you are at the limit for them, they could rip around the legs, at the time, there was 3 sizes available, Medium in purple, Large in Aqua or Teal color, and X-Large in Blue, those were discontinued because adults started to use them, and god their absorbency was so awesome it made adult products sales worst so they had to stop making them. I remember getting my first pack or large ones, and they were too big for me, I was around 95lb at the time and pretty skinny with around a 27" waist, so the next time I got to the store, I got a medium pack and they fitted a little better. Wish I was still this size today. I was extremely skinny at this time.
