bumGenius Original 5.0


The original bumGenius pocket design released in 2005, put bumGenius on the map as one of the best-selling cloth diapers in the world — and this top-rated cloth diaper just got even better! With an updated stay-dry inner fabric that stretches to provide a secure fit and a redesigned pocket that is more trim across the back, the bumGenius Original 5.0 also includes the same patented features that make bumGenius so genius! Adjustable sizing, snap closures and two inserts for customized absorbency make this a diaper for all needs: day or night, light or heavy wetters, small or big babies.

Cloth diapering has never been so easy!

bumGenius One-Size Cloth Diapers feature our patented butterfly closure system to provide a comfortable, trim fit. This simple design makes cloth diapering as easy as using disposables. The familiar design makes bumGenius one-size cloth diapers perfect for care providers who might be resistant to cloth diapering (including daycares).

Buy Diapers Once

bumGenius One-Size Cloth Diapers fit most babies from 8 to 35+ pounds. No sorting by size or having to carry multiple diapers when going out. Using the snaps on the front of the diaper, adjust the size if needed, put on your baby, wash, dry and reuse. For newborns, fold down the insert stopper for an extra-small rise.

Only the Best for Your Baby

The soft, waterproof outer fabric keeps the diaper trim on your newborn and toddler. Soft, sueded inner fabric gently wicks moisture away from your baby's skin. Stretchy, gentle leg and back elastic with rolled out casings keeps in the mess and helps to reduce red marks on baby’s skin. Our unique covered slot opening keeps your baby protected from moisture.
