This is the Adult's Sizing.

If there's one thing that the Japanese are great at, it's making simple things become awesome. Take the humble teddy bear for example. A great children's toy, but when San-X got a hold of it, they created the lovable and adorable Rilakkuma! Rilakkuma is a combination of the Japanese words "rirakkusu" (relax) and "kuma" (bear).

It has all the bear's features designed right into the hood! The soft plush ears complete the ensemble. This onesie has front button closure. It is designed this way so you could easily put on and take off anytime. For quicker bathroom trips, there's a horizontal zipper provided at the back of the hips. The gartered wrist and ankle cuffs were also added for that extra adjustment so you can be more comfortable wearing it.

Material: Polyester, Microfiber. 

This onesie comes with Zipper in the back and front button.
