The diaper has pocket openings on both ends that allows you to increase the diaper's absorbency by adding extra inserts (also called doublers).  This also enables any extra stuffed-in doubler or insert to agitate itself out in the wash. (Note from Karen: in theory should but it might not depending on your machine and the contents of the particular washload. Even so, they wash quite well for an all-in-one style diaper.) Half of the soaker pad is attached, while the other half also comes out through one of the pocket openings during the washing cycle. 

 It is made with a waterproof outer layer and 10 layers of 100% cotton birdseye fabric in the wet zone and one side of the flap has stay-dry fabric.

inside an organic diaper
The unique thing about this diaper is that it has an attached stay-dry microfleece layer on the soaker pad that will keep your baby's bottom dry. To use this feature, simply pull out the other half of the attached soaker pad and lay it over the body of the diaper.
organic cotton diaper inside
If you prefer all natural fabrics touching your baby's skin, simply keep the unattached portion of the soaker pad tucked inside the pocket. This way the stay-dry part of the soaker is tucked inside and only cotton touches baby in the wet zone.


on 14 pound baby on a 13 pound 10 ounce baby. The fit is snug to the body. It doesn't sag and it is not poofy.

It’s our favorite

We have moved to AIO for nighttime and this vs the thirsties (which we do like), is our favorite. It’s not too bulky and our LO stays dry all night. She is 10 lbs and 11 weeks old.

Poliester material

It doesn't leak like the others but the part which is covered with poliester feels awful to the touch. It is very expensive also.I wouldn't repurchase it again.

Our new favorite!

Where has this diaper been all my daughters life?? Her father some how threw out her cloth diapers when we were moving and I was looking to buy a few diapers as she still needs one at night. I tried this one because although we had always used fitted and covers, I always loved the idea of a pocket/AIO but could never find one that worked for us. This diaper WILL leak if you don’t stuff the “pocket” part with something, I found a folded GMD medium prefold is the perfect insert to add the needed absorbency. She is 33 lbs and the diaper still fits fine.

on the small side, but if you like low profile, this is your diaper!

I had an itty-bitty baby, but then he grew into a tank, and is now stretching into a tall, thin toddler. I LOVE the quality and the detailing of this diaper. The material is soft, with a smooth surface, it washes up super, and the inside cotton is soft and sturdy. I like cotton on my kiddo and the benefit of an all in one is fast application for when my guy is rolling around during diapering, with the added benefit of cute prints. The only drawback is that it seems to run on the smaller side, so it fit my little man from like 8mos-15 mos (so maybe 16-23lbs), but it's always been a trim/smaller option for us. It could have been my bad for not ordering a blueberry til he was 8mos old, but my other brands of AIO's have a bigger range. That said, I love this little diaper, and if it wasn't a bit snug on him now (17mos 24lbs), I'd be reaching for it more often.
