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 wash load. 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.

Fabric Content:

Outer waterproof layer: 100% polyester
Inner layer: 100% organic cotton
Stay Dry layer: 100% polyester

Made in the USA

WASH & CARE: Before using the diapers: wash and dry your diaper once in warm water (up to 140F) with detergent prior to first use. This causes the fibers to shrink, fluff up and become more absorbent.

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.

My favorite AIO

I have a couple of these diapers & use them as an overnight diaper on my 6 month old. I stuff them with a cloth eez prefold in medium. No leaks even with 12 hour use. The patterns are also super cute!

Immediately my favorite, of the ~6 organic brands we use. The way it tucks makes it most like a disposable, meaning this is the only reusable diaper I can get daycare to use so far. I haven't tried it overnight yet, bc I have others I like.

Easy Diaper for Cleaning, Using, and Passing off to Grandma

These are great diapers. After cloth diapering for over 11 years, I have found these to be the easiest to use and clean for an AIO. I have many green mountain diapers that I love as well, but for the ease and convenience and passing off to grandparents and younger siblings. These are the best! I just bought more for our newest little one due in just a few weeks!

Fantastic Diaper

I love the convenience of this diaper. It is an all in one, but also has a pocket to be able to stuff. I have cloth diapered 5 children and have used these with our last two. They have lasted through both of them, holding up well. I am very impressed. The ease of them for traveling also makes them convenient. The patterns are fun, and my youngest loves picking the pattern each diaper change. :)

Tried 10 different brands, these work the best for my chunky 6 months Old. He is 22 lb now, and we might use them for another month that’s all. He is somewhat «potty» trained now, so hopefully he will be at least during the day time during the next month otherwise aside of workhorse, no cloth diapers for us.
