good diaper backpack??

[mecawa]

What does everyone rec. as a good diaper backpack? I'd been using the Vera Bradley Microfiber backpack in black as an in between diaper bag and purse with DD1 (8) and DD2 (newly 3) and it was working very well. However now that DD3 is here, it's just way to small to carry my stuff, stuff for a toddler, and stuff for a newborn.

I was looking at the Vera Bradley laptop backpack but am not sure if it will work and haven't had the chance to look at it irl.

I was also considering the JuJu Be BFF or Pack a Be.

I don't like bags that are too heavy, the more lightweight the better. I also don't carry a ton around with me (well not a ton for someone with 3 kids). For instance right now I have my Pronto (diapers and wipes for both kids), a small first aide kid, my wallet, cell phone, keys, epipens, change of clothes for DD3, and some hand sanitizer. Occassionally I have a sippy cup, stuffed animal, snacks, etc.

A few ideas:
Skip Hop Via (http://www.skiphop.com/product/21010.html)

Columbia Trekster (http://www.toysrus.com/product/index.jsp?productId=3199292)

or the LLBean Stowaway Backpack (http://www.llbean.com/llb/shop/69232?feat=916-SR1) (not actually a diaper bag, but I have used it as one).

Also, Babies R Us and Ebags.com have a specific backpack diaper bag category.

I have the Skip Hop Via and loved it. It was great for an infant and an older child. Lots of room for everything.

We LOVE, LOVE, LOVE our Columbia Trekster. So does everyone we recommend it to.

It is a bit small if you have 2 LO's in diapers and you need spare clothes for both, but ours typically carries:
-Wipes (full sized soft package)
-5-6 dipes for DS1 (2.5 yo)
-10 dipes for DS2 (4 mo)
-2 changes of clothes for DS2
-diaper cream
-1-2 burp clothes
-a few small toys for DS1
-snack crackers in a small container
-my wallet
-pacifiers and
-whatever other miscellaneous stuff we cram in there

What does the inside of the Trekster look like? Like is it organized in any certain way? I can't seem to find a picture of what it looks like when you open it up. The reviews on it are great though, so I am definitely considering it.

I can't comment about the organization as I don't have one, but BRU carries it in-store, so you could go check it out (and then buy elsewhere if you find a better deal).
