This is just the pants from a Kamen Rider suit that my child wore. Would they be suitable as pajama pants? They were worn frequently, so the size label is unreadable. There's no material label either, but it feels like: 85% polyester 15% cotton The size was around 120cm, I think. How about them for a spare pair in case of bedwetting? There are also small pills, and they show signs of wear. Season: Winter
