With a proper fit, they are a decent alternative toa diaper for sure, but it takes a lot of trial and, unfortunately errors too to get it right. Silicone ones from Rochester or Coloplast/Mentor are my preferred choices, I do not at all like the latex ones. Leg bags are a personal preference again, Hollister are what I use, and with a leg bag holder (Urocare makes a good one) it is a good set up, but not for everyone. For at night, as long as you don't roll around all night, the are a good way to stay dry.
