The diaper fits 7-40 pounds according to Babykicks, and is one-size via 4 snap down rise settings.
This is a pocket fitted, so the whole diaper is absorbent and the insert can be removed for more thorough cleaning. Plus you can customize the absorbency by adding more inserts. The diaper itself is 55% certified organic cotton, 33% natural hemp and 17% polyester (for stretch.)
Here is the diaper measured folded and stretched on each size setting. Definitely not an exact science, especially since this diaper is extra stretchy. The photos/measurements were taken after prepping (washing/drying 3-5 times.)
Here is my son at about 21 months and 21 pounds, in the medium setting:
With the Little Beetle Wool Wrap over it:
I am personally more of a pocket diaper Mama than a fitted and cover Mama, but this is a great diaper. It has the same awesome Joey Bunz absorbency of the pocket diapers, but the whole diaper is absorbent. A fitted and cover also make for a great defense against explosive diapers! One diaper retails for $19.95. See this on my newborn.
