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.

Gorgeous diaper at an affordable price! November 13, 2015
Reviewer: Melissa Jimenez from San Lorenzo, PR United States  
The love print is beautiful and the diaper is the same quality I know from bumgenius. Very satisfied.  Love the wrapping and hand written note. It truly made me feel like my girl received a gift.

One of our favorite pockets October 30, 2015
Reviewer: Ashley Fossile from Las Vegas, NV United States  
This is our favorite pocket diaper (snap). We pair it with BumGenius microfiber insert and bamboo insert.

We also own kawaii and charlie banana pocket diapers. Between the three, the bumGenius 4.0 is our favorite pocket. Our little one is thin (10%) and tall (75%); this diaper fits him well.

At the moment we use these for nighttime. At 15 months we do have to change his diaper in the middle of the night or else he is soaks through his PJs. So we are going to try some fitted diapers for nighttime. This is where I knock a star down since I can't use them for nighttime anymore.

I love the feel of the lining, though can't really vouch for my LO's thoughts since he doesn't seem to care which diaper is on him.

I machine wash and machine dry them. They are still in great condition at 15 months of use. I use regular and free/clear tide just fine with the diapers.

BumGenius 4.0 October 27, 2015
Reviewer: #1Dad from Sanford, NC United States  
Amazing diapers

Wife's Breastfeeding and going through roughly 10 diapers in a 24 Hr period wouldn't choose a different kind; simple and easy to adjust to size and shape of your baby.

Great Diapers! October 22, 2015
Reviewer: Laura Nettles from Woodleaf, NC United States  
These diapers are working well for us with our newborn.  We snap them all the way down because her legs are super skinny.  We started using them when she was about 9 pounds, so around 4 weeks or so.  No leaks out the sides or top, and they are super convenient.
