bumGenius 4.0 One-Size Cloth Diaper
Best selling, top-rated, and recommended by moms everywhere for it’s quality and performance. One-size diaper with one-size insert keep your baby dry and comfortable.
"I received a few of these inserts free with my order of Fuzzi Bunz from your site last week, and I am in love with them! I had been using Hemparoos(two for day and night) and Wonder-fulls (for my Wonderoos), and I don't care for either of them as much as these! I've used them for two nights now, and no leaks (unlike with the hemparoos, which left my baby soaking wet in the morning). Thanks for a wonderful product! I just wish I needed some more diapers so that I could get the inserts for free, but, alas, I am all set for now."

bumGenius One-Size Insert

bumGenius One-Size Microfiber inserts are made of 3 layers of the thickest microfiber terry available anywhere. Our unique snap down design allows these stuffable inserts to fit perfectly in our bumGenius 4.0 One-Size Stay-Dry Cloth Diaper. But they also work well in a small, medium or large Fuzzi Bunz® pocket diaper. Our new, wider and longer design fills up these diapers side-to-side and end-to-end. No more leaks! The One-Size Stay-Dry Insert measures 15.75 x 5.5 inches.

Drying time

Our one-size inserts dry as quickly as bumGenius™ or FuzziBunz® dry on the line or in a dryer. All the economics of a one-size product and no more waiting for thick cotton or hemp inserts!!


Our inserts are now manufacturer rated at 15 oz. aborbency. Many other companies offer microfiber inserts now, but no other microfiber insert compares to the bumGenius microfiber insert. What is different? Our product is simply more absorbent than the others.

What about newborns?

If you are using this insert on a small newborn (under 10 pounds), we recommend purchasing Microfiber Diaper Doublers (plenty of absorbency for a newborn) or Hemp Babies Little Weeds to use until your baby is a little bit bigger.

What about overnights?

We recommend using two inserts when diapering an older baby or toddler at night. When diapering a smaller baby at night, consider wrapping the microfiber insert with a Hemp Babies Little Weeds.


Less detergent, less energy (our inserts are easy to hand wash/line dry if necessary), convenient one size design, and a lower price make these inserts the absolute best value available anywhere.

Designed by a mom and conscientiously manufactured in China.

I really like these inserts, I have never had a problem with them. They really hold everything in! As for night, my diapers are stuffed with a OS and a NB insert, baby sleeps all through the night and stays dry. I really trust this brand, it out preforms others, worth every penny. I can not stress enough how much I appreciate these.

I love these!! Initially, I regretted getting extras of these with my 4.0's, but I don't anymore. Now that the babies are a little older, I need them for heavy wetters. Also, I just got a bunch of 4.0 covers to go with them for so much less $$ on the seconds sale. Always remember not to skip steps and don't put these right next to the baby's bottom. You need a liner or put them all the way into the pocket diaper because microfiber cannot be directly against skin. Someone thankfully told me this and I'm glade she did.

Love these! I am using them with my Econobum covers so they aren't as big for my LO. Very absorbant he has even worn these overnight with no leaks.

I was a bit nervous buying such a "thin" insert for my heavy wetter...boy am I pleasantly surprised! I LOVE THESE inserts, wish I'd bought some sooner...and am buying more NOW! I did an absorbency test on them using a 2 cup measuring cup full of water and the insert soaked up almost every bit with just a bit of dripping - once you cover them you are all set!
