we just bought this one, burlington coat factory for $35.
Deluxe On The Go Diaper Backpack with the FastFinder™ Pocket System (Black)
seems like it will work out well enough.
vids on youtube seem to show it can hold a more then you would assume based on its size.
Dimensions (inches): 12 ½ wide x 17 tall x 6 ½ deep.
This thread is cracking me up It would never even dawn on my husband to want a separate "manly" diaper bag. We have a black and white Coach diaper bag, a black and white zebra print Carters diaper bag, and I sold a blue Petunia Picklebottom. I like the Coach bag the best, but it didn't fit as much as I needed in the first few months, especially since we cloth diaper. I need to try it again.
Here it is overstuffed to the max
My wife bought a black "Diaper Dude" messenger-style bag for me before our daughter was born, and she got an expensive designer one from a friend at a shower. The Diaper Dude bag is used almost all of the time now, because it is more intelligently designed than the nice bag. Maybe if we have a second while our daughter is still in the diaper world we will use them both at the same time, but that seems unlikely to me at this point.
