Baby Milano's Fitted Cloth Diapers not only have a super trim fit, they also have a super absorbent core. The diapers are made with 100% cotton, double fleece and an ultra thin absorbent core which gives the diaper a trim fit. The adjustable hook and loop closure enables a snug fit around the tummy and legs. The elastic around the legs not only helps with the fit around the legs, but it also contains the messes. The diaper's unique core is composed of 4 layers of super absorbent, yet ultra thin fabric that is made from our special blend of viscose and polyester. For durability and comfort, the outer layer is made of 220 GSM cotton. The inner layer is made of a soft double fleece, which helps wick the moisture away from the baby's skin and helps to keep the baby dry and comfortable. The diapers also have a soft cotton binding around the legs and back to protect the baby's delicate skin and to cup diaper messes.
