Swaddlebees Econappi Pocket Diapers are 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 kg). 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 even overnight. Available in fun, modern color combinations, each Econappi by Swaddlebees has two rows of snaps for adjusting the size as your baby grows. An outer layer of laminated polyester keeps wetness in, while an inner layer of Organic Cotton Velour is soft and gentle against delicate baby skin. All Econappis include 2 inserts which can be inserted inside the pocket, or laid on top. The small insert consists of 4 layers of organic cotton/bamboo for use when your baby is at the smallest size setting. Small inserts can also be used as doublers as your baby outgrows the smallest setting, when extra absorbency is desired. The longer insert consists of 6 layers of organic cotton/bamboo blend which can be trifolded and is adjustable in length. The long insert is topped with a layer of Organic Cotton Velour (which provides the same soft, stay-dry qualities as micro-fiber or suedecloth) which is perfect if you prefer to lay the insert on top of your Econappi, rather than stuffing it in the pocket.
