Piper Diapers One-Size Diaper Cover is a waterproof "outer" 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. 

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. This does not necessarily mean it fits ALL sizes and may not fit a very small newborn. For this reason we also offer "newborn" sized covers.

The OS cover is a great option to pair with our bamboo fitted diapers. The wide wings keep the entire fitted diaper covered. 

All Piper Diapers are made responsibly in China
