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.

Great Absorbency!

Love these diapers! I use them as my overnight diapers because they have the tongue attached to the diaper but I can also stuff a prefold into the pocket for additional absorbency. They're worth the splurge for surviving 12 hours overnight with no leaks.

Absolutely Love These!!!

Although I haven’t tried the one size of the blueberry yet. I absolutely love the newborn ones!!!! They work so well for my little one. They keep him dry, no blowouts nothing!!!! I highly recommend these diapers, especially for a heavy wetter like my boy.

a good choice for day or night

I love the llama pattern I picked! This diaper is easy to customize by stuffing doublers in the pocket making it a good choice for day or night.

Not so much a one size fits all

Nice diapers, great quality but do not fit my 29 pounder well. They are too tight around his thighs and cause irritation if he wears them for too long. His thighs aren't chunky so I'm not sure why the fit so tightly. These diapers probably wouldn't work well for a bigger baby or toddler.
