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.

Excelent diaper for my newborn January 22, 2015
Reviewer: jessicalee acevedo from mayaguez, mayaguez Puerto Rico  
So far this is the only OS diaper that fits perfectly my 2 weeks 8 pounds heavy wetter newborn baby.  I haven't had any leaks, last long for the long sleep periods, and it works perfect for the night time.  The quality=price! Definitely worth the investment.

I love these diapers because they do not leak and they are one of the few diapers that still fit my 3 year old!

Super cute print! January 16, 2015
Reviewer: Stephanie Standley from O Fallon, IL United States  
Totally addicted to the 4.0's so I was happy to get the Albert print. It's my favorite! Have had no issues with pocket staining and inserts that stain are easily sunned. They have done well even with only winter sun.

Love this diaper! January 15, 2015
Reviewer: Taryn Lynch from Macomb, MI United States  
I love this as a daytime diaper. It hold well, and fits my tall LO like a dream. I wouldn't recommend it for nighttime, put I double layer for long car rides with a hemp insert and she is good to go! Washes well too!
