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.

Easy to use

These are the first reusable diapers I ever used. They are easier than I expected.

The best cloth diapers money can buy

Blueberry simplex organic diapers. The best cloth diapers money can buy. My first set lasted 20 months and got worn out from washing and drying so much so I purchased another set. They are worth the money and I’ve never had leaks. They wash and dry beautifully.


I'm definitely a Blueberry fan

This is by far one of my favorite All-In-One diapers. I'll admit that a good part of my bias is due to all of their adorable prints, but I also really like their functionality as well. These are my fastest drying AIOs, and I don't have to use any tricks to make them that way as I do with some others. One of my CD babies was really sensitive to wet while the other preferred cotton against her bum. This made the stay dry on the tongue genius! I could use whichever method I wanted without prior planning. Another feature that I really like are the slanted hip and rise snaps. My kids always have smaller waist than hips, so this arrangement works very well for us. If I ever needed to add extra absorbency, the pocket works great too. And it's super trim! Hmm. Maybe this one is my favorite after all. ;)

Blueberry AIO

I've been cloth diapering for three years now, I'm on baby #2 and I've used many different brands and kinds of cloth diapers...blueberries are by far my favorite!!! They have never once leaked and I love that they fit my one month old just as well as my above average sized three year old!!! They wash great and dry quickly in the drier and have been the easiest diaper to use by far!

One of my favorites!

I love how trim this diaper is! It fits great and is really absorbent, I've never had a leak. I also really like the fleece option. I always put a fleece liner in my diapers anyway, so it's nice that I don't have to add an extra piece to this diaper. I haven't used the pocket feature yet because I really haven't needed it, but I love that I can easily add absorbency if I want to. Pretty much the only thing I'm not a fan of is the tag is right on the edge of the diaper. I don't really think it bothers my LO, but it just doesn't seem like the most comfortable thing when she's wiggling and her little tummy hangs over the edge of the diaper right there. I think I prefer the other design that has the thicker seam around the edge.
