It's adjustable in both size and absorbency. Adjust the size as your baby grows. You can use it on most babies that range from 10-35 lbs (4.5-16 kgs). Stuff it with as little or as much absorbency as you need to get you through a quick trip to the store, a long car ride, or maybe even overnight. 
The diaper has two rows of snaps for adjusting 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.

All diapers come with 2 microfiber terry inserts. Included are a 3 layer small insert, and a 4 layer longer insert that is adjustable for the medium & large sizes. The small insert  can also be used as a doubler when extra absorbency is desired.
