I love the GR8X brand of nappy bags. These ones are just like a nappy bag / backpack style. But what you don't know is that the nappy bag opens out to actually be a changing mat. A changing mat with lots of pockets for storage of baby gear, a big size to change baby on. (Removable and washable of course). Its a really neat nappy bag!
