These are a really unique snap in soaker design! One layer of Minkee down the middle to keep baby dry and seven layers of super absorbent organic hemp fleece when folded, these soakers are real super soakers! The design enables them to wash thoroughly and dry super fast. Snaps on the back so that you can snap it into your BerryPlush AIO shell/cover! When soiled, just snap one out and snap in a new one as long as the cover isn't soiled making your BerryPlush AIO much more economical!
