Cloth diapering has never been so easy!

bumGenius One-Size Cloth Diapers feature our patent pending 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).

Less Clutter

bumGenius One-Size Cloth Diapers fit most babies from 7 to 35+ pounds. No more sorting by size or having to carry multiple diapers when going out. Three snap-downs on the front of the diaper* allow you to easily adjust the size of the diaper as your baby grows. 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. Super stretchy, gentle leg and back elastic with rolled out casings keeps the yuk in and help to keep red marks away. Our unique covered* slot opening keeps your baby protected from moisture.

Functional for years September 25, 2015
Reviewer: Meghan S from Upton, MA United States  
I love these diapers because they are so adjustable, and I can use them for the diapering lifetime of my daughter. They don't have double gussets like some diapers or covers, but I very, very rarely have blowouts. I don't like that the inserts don't "shake" out easily for washing.

a-ok! September 21, 2015
Reviewer: doc1414 from Phoenix, AZ United States  
I like these diapers alot! Bumgenius diapers fit my fat short baby a little oddly but that hasn't stopped me from using their products. I like how the absorbancy  is so adjustable, I don't like stuffing them...

For a potty-training toddler, naps and at night August 27, 2015
Reviewer: K Schult from Iowa  
We bought a couple of bumGenius 4.0 diapers for our sometimes-uses-the-potty two-year-old girl.  It wasn't until we started using cloth trainers that we were ready to try switching to all cloth.  We use these overnight and at naps and they are wonderful.  Easy to use (the inserts come out in the wash - no unstuffing, at least for our machine), they fit well (my girl is 25 lb), and they dry fast (much faster than our trainers).

Great diaper June 30, 2015
Reviewer: Carolyn Colon from Raleigh, NC United States  
The bumGenius 4.0 is a great diaper. It is very easy to customize the absorbency with this diaper. I also love how easy the snaps are to adjust! With only two snaps for the waist it is very easy to get the proper fit around the waist and thighs. One of my favorite diapers.

love the hook & loop May 22, 2015
Reviewer: Leora from MA United States  
hook & loop work so much better for us as out LO is never still. He is slim so these fit him best. I still prefer my bamboo inserts instead of the BG ones.
