Made with a soft knit outer material with double gusset prevents leaks around legs and a leak proof lining--this is especially nice for babies with skinny legs. Can be used with a fitted diaper, but we prefer to use prefolds (above), folded in thirds and wrapped-up by the Prorap. We think that makes a very easy yet inexpensive diapering solution, providing a snug, comfortable fit with your choice of fasteners: wide velcro strips or nylon snaps. Both are designed to adjust to your growing baby. Velcro is a little easier when you're trying to diaper a squirming baby. The nylon snaps are more durable and they don't get linty in the laundry. Available in white. One of our customers recently told us that she had several different types of covers, "but the Proraps are what my husband reaches for every time." She liked them, too. Made in USA.
