All in One Diapers

All in One Diapers

Rumparooze One size All In One

Every diapering system consists of both moisture absorbent layers and a moisture resistant barrier(diaper cover). In all-in-one cloth diapers, these are combined.


Easy to Use

In an all in one diaper, a multi-layered absorbent inner diaper is integrated with an outer waterproof cover. The diaper is fitted to your baby's size and shape and can easily be adjusted with snap or hook and loop closures.

Since everything your baby needs is wrapped up in one cloth diaper package, all in one diapers are extremely easy to use. There are no extras to reach for---or to forget. This makes All In One diapers the choice for caregivers or parents short on time. They act as just as disposable diaper in the sense that it's all one piece.

Washing AIO Diapers

When you take an all in one diaper off your baby, just cover close the hook side of the fastening tape (the rough side of VelcroTM) and toss in the diaper pail. Covering the hook side will prevent it grabbing and wearing on the diapers. If you have snap All In Ones there's no need to do anything at all. Alternatively you can fasten the diaper inside out for better washing results and quicker drying times.

Since there is nothing to separate out, you have only one easy wash routine.


Our OsoCozy All in One Diapers are made with the same inner absorbent gauze as our prefolds. Our white all-in-one diapers use cotton gauze a little thicker than the typical prefold for extra absorbency. Our unbleached all in one diapers use extra absorbent cotton birdseye for the inner diaper. There are tons of other choices on the market that are sometimes made with microfiber and microfleece.

You can add inserts and doublers,  folded flat diapers, or newborn sized prefolds to all in one diapers for nighttime and for travel. Since they have more absorbency than most prefold diapers, you may not need additional absorbency, but they can be added if necessary.
