The design of the Moby Wrap uses your entire back, as well as your shoulders, to carry the weight of your baby. Unlike other baby carriers the Moby Wrap is a wide piece of durable fabric that is wrapped over both shoulders. It is amazingly comfortable and easy to wear. Moby Wraps are one size which means all caregivers can easily and comfortably share one wrap. In a Moby Wrap, baby is secured by three sections of fabric for triple wrapped security. A Moby Wrap’s one-way stretch cotton and wide width ensure that your baby is held close and tight. When sleeping, the back of your baby’s head can also be secured under the cotton fabric for added safety.
