My bag would be lightweight like the Fluerville re-run Hanna. It would also be similarly sized to the Hana as well as the Skip Hop Studio and sadly discontinued City Chic. After much measuring and estimating - my ideal bag would be 16 x 10-12 x 6. This sized bag is wide enough to access everything, not too deep to lose everything, and not longer than the bars of my stroller. It would not be overly bulky, but would allow me to carry the essentials for lets say 2 kids and myself with the stroller basket having kid toys in it.
My perfect bag doesn't have insulated compartments. I don't reheat things for Saphira, and fortunately we didn't have to bother with bottles, but frankly I don't want the weight.
In appearance, I also like the Hana in that it is nondescript. It doesn't look too much like a bag, or too much like a fancy purse. Still, I love the idea of the purse bag - the going out to dinner and having a nice bag that is your diaper bag and purse - just like the well organized and super heavy Amymichelle bags.
My bag would come with stroller clips/ties, have good organization pockets, and have a wee clip that could be fastened to your belt loop, or an Ergo strap, to keep it anchored, but not have to switch to a backpack mode as that just looks stupid. If I wanted a backpack, I'd get a backpack. This clip is vital. If you have a bag on your shoulder and you bend forward, the bag flies forward. It doesn't matter the size of the bag, small or large gravity pulls it forward. And if you happen to have a small child in the path of the flying bag . . . . . . Well lets just say I can't imagine why such a clip hasn't been invented yet.
My bag would cost $30, $40 max and would still be quality enough to hold up to sand, crumbs, water, and being banged around. One reason I don't want to buy a bag online is that despite what seem to be very positive designs of the Hana and Studio bags - there also seem to be a goodly number of reviewers who had problem with quality - and well, I can't really return it can I? The cheaper bags, the k-mart, wal-mart variety may work - my ideal may even be out there - but they don't really have reviewers and video bag tours do they? This would be my only bag. I've never liked switching things from bag to bag - the only time I might want something else is when we fly - and then I will just want something Big (cram that 10k in!) - so it would need to be functional and sturdy for everyday use.
I thought about a messenger style bag - it would be handy for Alister to be willing to carry a bag, but when I thought realistically about how often he would need to carry the bag, and if the bag was small and compact, he wouldn't need to carry it anyway. I'm also unconvinced about the organization of the messenger bag. I think I'd really like to see it. Plus, I just want to feel a bit more feminine so an elegant bag is more up my line.
So for now, I found a really cheap bag at the rinok and am making some hack changes to see if I can make it do some of the things I want. Granted, it is a bit smaller than my ideal, but I only have one kid and think I can make it work. Trial run this Sunday - which is the ultimate test since I have to be prepared for a 9:30 - 3pm absence from the house and from any amenities. We'll see.
