These are baby pajamas with a polar bear pattern ⸝⋆ The color is light gray with an all-over print of snow and polar bears. The waist area is like a belly band, and it fastens with buttons. The buttons are large, making them easy to fasten, and the pants have extra room in the seat, so they can be worn without being tight even with diapers ◎ It seems to keep them very warm when they wear it, so I didn't need a sleep sack ( ¨̮ )
