I've used the small version of this pull up. I preferred to go one size down as I'm at the bottom end of medium and I find these pull ups can be big and will stretch even more with my movement overnight, leading to sagging; I'll wear underwear over them to prevent that. The small version holds enough for me overnight, usually. Quick absorption but, odor control not as good as plastic backed products.
I keep them handy for times when a proper diaper is not necessary or being discrete is more important.
