I've got a gr8x backpack in a camo design....I got it because DP goes out a lot with DS and its not girly at all LOL! Plus I was getting sick of lugging the traditional style nappy bags on my shoulder.

Its actually a two-in-one design - there is a smaller back pack zippered onto the big one which is just the perfect size for when DS wants to wear his own.

Its got a change mat, insulated pocket for bottle, lots of little compartments for all the bits & pieces you need. I love it!
