Picture illustrates microfiber doubler with insert, which is sold separately.
Perfect for heavy wetters, long car rides, or long naps! Each Micro Doubler has 2 layers of thirsty microfiber and is made to fit with any regular insert of the same size. To use, snap in the Micro Doubler and then snap a regular insert of your choice on top.
Note: This must be used with a Best Bottom insert over top, as the microfiber and/or exposed snaps can cause skin irritation if used right against baby's bum.
