We're always innovating at Tykables to make our adult baby clothing selections the best in the industry. A premium blend of cotton and spandex forms the four-way-stretch fabric for the Snappies collection. Comfort continues with the inclusion of a hidden zipper that extends from your neck to the left ankle. Using this materials in our Sleepers we have created a cute summer, fall, and spring line of pjs. These Pjs also offer pockets sewn into the side seam to be hidden from sight. This hidden pocket also container a small opening for an insulin pump tube.
