Been curious for a good while on Preventa line of products. I've been wearing the onesie since this morning, its quite comfortable. It has two decent metal straps in the crotch and is a very stretchy material. I typically wear either baby pants or 4care (from xpmedical) ones. I am kind of liking this one a bit better, it seems to run a little smaller than the 4care ones, but it makes up for it in being stretchy. I have not worn the Kryptonite Body Suit yet, but am thinking about giving it a go this evening after work. Its made to be very hard to get out of. It has snaps near the back of the neck and that's it. Preventa is a line of clothing for kids/adults that are autistic and have a problem with diaper digging and people who have the tendency to strip. There is another form of the kryptonite one that even has a zipper as well as snaps over the zipper. So if you are into making someone stay diapered, it would be perfect. They also have one for swimming in to, that helps conceal the diaper/brief that is similar to the kryptonite one.
