Recommend your diaper bag for a double stroller

MommyMar2010

I have the 2012 city mini double GT-which, thankfully means better access to the basket underneath, but the storage is still pretty tight and my JJ cole bag doesn't fit.  Can anyone recommend a good "slim" diaper bag that will fit under a double stroller?

 I tried hanging it from the handlebar (i know, i know, big no no) and the stroller felt like it might tip since all the weight distribution was off...so i def don't want to do that!

I remember thinking the BOB stroller diaper bag was very slim, about the thickness of a pizza box. Have you tried the Skip Hop Duo Double Deluxe? Since it's designed for double strollers, you may be able to hang it from the handlebar better.
