Zippyz are patented, functional footed pajamas. With a zipper from the foot to belly area and 3 snaps on top, Zippyz allow for a quick and easy diaper change without exposing baby's chest area. No more miss-snapping, no more full body zippers that leave baby cold and exposed. Plus, Zippyz cut down the time of a diaper change by over 50% leaving more time for cuddles and hugs..
