Swaddlebees Simplex All In One Diaper is a unique all-in-one diaper design that combines the convenience of an all-in-one diaper while providing the absorbency adjustability of a pocket diaper. 

Translation: if you have no idea WTF the previous sentence said...an All In One diaper means that the diaper has no parts, you just snap it onto baby, and wash it when it gets soiled.  So the Simplex is just that easy...but if you need some extra absorbency there is a pocket where you can add an extra layer of absorbency.

Made of a waterproof outer layer, and 100% cotton on the inside.  The diaper has pocket openings on both ends that allows you to increase the diaper's absorbency by adding extra inserts.  This also enables any extra stuffed-in doubler or insert to agitate itself out in the wash.  Half of the soaker pad is attached, while the other half also comes out through one of the pocket openings during the washing cycle.  The result is a diaper that is thoroughly cleaned inside out and dries fast-either in the dryer or on the line.
