The design of the Moby™ Wrap uses your entire back, as well as your shoulders, to carry the weight of your baby. Unlike other carriers, which have narrow straps or go across one shoulder, the Moby™ Wrap is a wide piece of fabric that is wrapped over both shoulders. It is amazingly comfortable and easy to wear. There are no buckles, snaps or other fasteners. It is easy to adjust the fit of your Moby™ Wrap by varying how tightly you wrap yourself and your baby.
