The design of the Moby® Wrap uses your entire back, as well as your shoulders, to carry the weight of your baby. UV wraps feature SPF 45+ protection with a Rayosan process to protect baby's delicate skin. Unlike other carriers, which have narrow straps or go across one shoulder, Moby® utilizes a wide piece of durable fabric that is wrapped over both shoulders. It is amazingly comfortable and easy to wear. There are no buckles, snaps or other fasteners that may break or bend. It is easy to adjust the fit by varying how tightly you wrap yourself and baby. Moby® Wraps are one size which means all caregivers can easily and comfortably share one wrap. For babies from 8 to 35 pounds. 100% cotton. Machine wash. Imported.
