Bummis Super Whisper Wrap Diaper Cover: Large (30-40 lbs),

A state of the art Aplix-closing (industrial velcro) cover has an innovative overlap design that ensures a custom fit on any baby. Made from a super resistant waterproof laminate sandwiched between two layers of a soft polyester knit. Made to withstand even the rigors of industrial washing and drying. A durable, heavy-duty elastic around legs and tummy which will not wear out with repeated industrial washes. Elastic is encased in soft, smooth polyester knit bindings for a comfortable, stretchy fit, and a leakproof seal. The generous cut of this cover makes it suitable for prefold diapers or fitted diapers. Machine wash and dry at normal temperatures. Avoid chlorine bleach or any other whitening agents.
Customer Review: worth every penny
The eldest of my 3 children is now 8 years old and I've cloth diapered all three of them. We've used this brand since the beginning. In fact, the Bummi covers I had for the first child lasted up until the 3rd child. They had been through lots of use and abuse but were still functioning. These are high quality diaper covers and I haven't found any that are as good - and I have tried quite a few! They are especially good for overnight. The sizing is generous. The quality of the materials used to create the diaper is very good as well. If you are going to take the plunge into cloth diapers, you might as well go for the best value right from the beginning. You could spend lots of money and give yourself lots of headaches if you don't! I've resorted to making my own diaper covers and inserts for use during the day and save the Bummis for at night because they are such a good, well-built cover. The baby is dry on the outside though she's soaked to the bone on the inside. You might notice some wicking around the leg openings after long periods of time with a wet diaper inside but that doesn't seem to happen too much.
Customer Review: Diaper Covers
Great Product. I can be environmental conscious by using soft cloth diapers and have the convenience of disposable diapers (no diaper pins), without the high cost of disposable diapers.
