It features easy-to-use velcro wings and two rows of snaps to adjust the size as your baby grows. An outer layer of laminated polyester knit keeps wetness in, and an inner layer of high quality microfleece keeps baby’s bottom dry. Inserts can be used inside the diaper or laid on top, turning it into an All-in-Two diaper. If the diaper isn't soiled, remove the insert and reuse the diaper. Features: Two rows of snaps so it's like having three sizes with one diaper! Outer layer of laminated polyester knit and an inner layer of high quality microfleece Pocket opening allows you to customize the amount of absorbency you need for your baby.  All diapers come with 2 inserts made with a blend of organic cotton and bamboo.  The small insert consists of 4 layers for use when your baby is at the smallest size setting. They can also be used as doublers when extra absorbency is desired. The longer insert consists of 6 layers of organic cotton/bamboo blend that is trifolded and is adjustable in length.
