I bought this for my 11 year old daughter. fit her well. she is 88 lbs 5 ft. She wore it during her last cycle, she was comfortable and there was no issues with leaking. It was easy to rinse out and held its shape and material well.

1 con- its not easy/convenient to keep track how many times you wash to equate the 30 max. We have 5 pairs, and Thinx is the only brand I'll buy. The security %26 fit are great and they do hold up for at least 30 (60 really) washes(probably a tad more really). I treat these like cloth diapers -utility sink soak/wash with Dawn until water runs clear. Sometimes that takes an overnight soak to unlock all that has been absorbed. FYI: Never let a used pair just sit dirty/dry! Wet=easier rinse %26 odor control stays intact. My daughter noted the leak control immediately decrease %26 I was prompted to ask the very wash following, as suddenly there were fuzzy pils of the absorbent layers breaking down coming through the wearable laye as I pre-rinsedr. Just all of a sudden, thankfully. It held up for a day at school %26 embarrassing mess was avoided, thankfully!

I'm seventy six years old and been looking for a solution to diapers for elderly. It doesn't matter if you're a baby or how old you are. There is a need for some dignity in this area. I bought these several years ago when they were considered very expensive.But I thought it was an investment. Now I have several different brands and kinds for different reasons.But I love them all, and I still use diapers for those occasions when I need them. But I love my social life without diapers now.
