Finding and choosing the best options for us on the website was super easy! The Piper Diaper fitteds and covers have been working so so so well for overnights for our boy and there's so much room for him to grow into them! Will be buying more. 🙌

Piper Diapers One-Size Diaper Cover is a waterproof shell to go over an absorbent diaper. This is a cover only and does not come with any absorbent interior. Diaper Covers are used over a fitted diaper, prefold, flat diaper, or any other absorbent insert! Paired with a prefold diaper, Diaper Covers are one of the most economical options for cloth diapering.
Fits approx 3-36 months or 10-35+ lbs
(This is a regular cover only, NOT an AI2 - there are no snaps inside to snap an insert into)
Pairs well with our Overnight Fitted Diaper
Featuring double gussets to fit over your insert of choice and keep in all the messes.
Once wet, simply change out the wet "inner" and reuse the cover! You could reuse the same cover right away, or switch between two covers during the day until any become soiled. With this system you do not need as many covers as inserts for your diaper collection.
This is a "one-size" diaper meaning it can fit a large range of sizes to grow with your baby. Many families find "one-size" diapers start to fit the best starting around 3 months old. For this reason we also offer "newborn" sized covers.
This diaper cover is roomy! The OS cover is a great option to pair with our bamboo fitted diapers or organic cotton fitted diapers. The wide wings keep the entire fitted diaper covered without leaks.
Flaps are attached inside the front as the back. You can use these to tuck a prefold or any insert inside of. Keep in mind you do not have to use these flaps, inserts can lay right on top as well or attach over a fitted diaper.

I love the best bottom diapers so I decided to try the Piper line. The diaper prints are so cute. They fit a little different than the best bottom diapers which took me a moment to learn to get a good fit without leaks but now that I got the fit correct I love them! Great quality and I love the prints!

I love the covers only wish they would fit bigger babies. My son is 27 lbs 9 months old and they are almost too small.

I got the cloud pattern and it’s super cute! Has held up well in the wash and does a great job being a cover over the wet diaper, keeping the clothes dry.

Disclaimer: I received two of these covers free of charge in exchange for a review. I am offering an honest review, however. I have cloth diapered 7 babies. These are hands down the best diaper covers I have owned. They are very high quality and will easily last through at least 3 children or have good resale value after just a kid or two. These will also fit all the way from just after the newborn stage (I prefer less bulky newborn diapers for little babies) until potty training. The snaps are not only strong and secure in and of themselves, but they are also arranged so that you can get the best coverage to prevent leaks. There are also built in pockets in the front and back of the cover if you decide to use pre-folds. I personally prefer fitteds and they work perfectly with these covers. The leg gussets are also well built and prevent any leaking. I’ll be selling some of my old covers and getting more of these!
