Sleeping Baby/Zipadee Zip brand Flying Squirrel sleep suit for babies/toddlers, size Medium 2T/3T. This is made of a lightweight polyester material, breathable and lighter than a t-shirt. Very comfy with fold over cuffs great for transitioning out of the original Zipadee Zip. This has some pilling as shown in the photos but is otherwise in good condition. From a smoke free, cat friendly home.
