My situation is different from others, but due to other side effects of my chronic illness, I am able to swim during my pool’s “therapy hour” so I have tried many different adult swim diapers.
My favorite is the Gabby’s Swim Diaper, it just fits me really well and I like how the Velcro strap on the front does not catch on my swimsuit:

My second favorite is the Splash About Shorts. They are snug, comfortable, and have nice leg and waist seals:

I really wanted to like the SoSecure, but they just don’t fit me as well as the two swim diapers listed above. But they are popular and as those above me have mentioned, definitely worth a try!
Yes I have had accidents while in the pool. Yes it’s humiliating and yes people have noticed. But the good news is, no one has ever said anything to me (probably because almost everyone else swimming during the hour is also wearing swim diapers). My swim diapers have always contained my bowel accidents… Well maybe not always contained, but I have never had fecal matter escape into the pool. If I do leak, it usually creeps out the leg seals once I get out and start walking to the locker room.
Anyways, good luck with your search! Trial by fire is sometimes the only way to truly learn 🙃
