They're amazing! They have a very smooth plastic backsheet, and smell like a baby diaper should smell. They form fit around your privates to make a cocoon of diapery goodness. Once you wet them they form even more solidly around your crotch, and swell up and become all wet and squishy. A size 6 will hold 1 full bladder void, and about half of the second. They also absorb very quickly, so for an adult to be able to let his bladder completely loose, and let the diaper absorb it without leaking is amazing.
