The bag I used meets most of your requirements (except the attached wetbag.) I loved it. Bonus that it came with stroller clips, which made it a cinch to hook on places. I got it at Babies R Us, but I have seen it in many other places, including this one: http://www.supercoolbaby.com/archives/2007/02/jj_cole_system_diaper_bag.php
Good luck!

I use an oioi diaperbag and really love it. I too use cloth but no diaper bag manufacturer seems to consider that anymore so to make room, I just pulled out the changing pad and that seems to give me plenty of room. I found some small wet bags on amazon and I just keep them in there. Oioi is a little pricey but not as pricey as some and I’ve used mine every day for over a year so I’ve definitely gotten my money’s worth. You can sometimes find them on amazon and overstock. Good luck!

Well, if you drop the requirement for an attached wetbag, I think you could find something that suits…

My favourite was the “emily” by Storksak. Their diaper bags look like chic bags and purses, and so are great if you don’t want to look like you are hauling a diaperbag. I use mine as a purse now that we are all over diapers.

We had zippered wetbags for used cloth diapers which we just kept in the diaperbag, and never had a problem. Also, didn’t use bottles so didn’t go for insulated bottle pockets.

We had them though in our Hopop, which we found to be a lifesaver. Here in Europe, restaurants rarely have high chairs, and the Hopop serves as a booster seat which you can belt on an ordinary chair. It is hardsided though, so it may not be what you are looking for.

Skiphop makes great diaper bags (with almost everything you are looking for including insulated pockets)… check out “It’s now or leather”, “Accidents will happen”, “For a Change”, and “Just the Messenger”.

Good luck!

We used the Land’s End Do-It-All bag, and while it’s pretty nondescript, it may just meet all your superbag requirements; it’s just under $40, too — not bad at all. http://www.landsend.com/pp/DoitallDiaperBag~213834_-1.html?bcc=y&action=order_more&sku_0=::CLN&CM_MERCH=IDX_00018__0000002451&origin=index

I’ve seen some great handmade bags on Etsy — I was in the market recently for both a purse for my daughter and a gym bag, and found some really neat ones there which the makers (what do you call them … sewists? craftspeople?) were able to customize to our liking. Plus I like the idea of supporting a WAH venture as much as possible

I never used a diaper bag with my two. I also never carry a purse. A small canvas backpack that I sling over one shoulder covered all those needs.

Heh, I attached a small wetbag made by Monkey Doodlez to the inside of my diaper bag. Its a Dad-Gear one…it will hold: Said wetbag (sewn in), a large changing pad, changes of clothing for Babes the Younger and Elder, Cloth diapers and associated shutff for BTY&E, a couple toys, and a blanket. Wipes go in the front dispenser under the flap. I usually shove my wallet in the front pockets that are next to the wipes dispenser. Because of the flap closure, I haven’t had any issues with its occassional “header” – it can tip and I don’t lose anything.

I absolutely LOVE my Loom Marupial bag. http://www.loomlife.com/marsupial.shtml
It is so light I can’t believe it, but it holds its shape, is a wipeable fabric. Mine has a cool giraffe type pattern but it looks like the current styles are plain. There are 4 pokets on the 2 outside and 2 inside corners that can each hold the plastic wipes container, but will also fit a bottle, or my giant wallet, or 3-4 diapers so it was very easy to customize to my needs. Matching foam changing pad, with magnets to keep it closed when not in use. Matching wet bag, which was not completely leak proof (my only complaint). Long exterior back pocket with a magnetic closure that fit books perfectly and similar pocket inside for the changing pad. My daughter has food allergies so I always had to carry extra food with us and this bag held it all, kept it organized and STILL felt light and LOOKED GOOD!!! It even had a key clasp and a pocket that held my cell phone so it was my purse/diaper bag for 2 years. It was a tough decision when I bought it for $50 at consignment and SO glad I did.

All good point. I can honestly say, I have nothing that meets those requirements. Of course, I have not designed a diaper bag yet. I will add your notes to my to do list.

Love it. It doesn’t look like a diaper bag, it’s got inner and outer pockets, an insulated pocket for bottles, wipes clean, stands up on its own, has stroller clips. It’s only missing the attached wetbag. And my husband isn’t ashamed to carry it around, so there’s that.

this is the bag i use, and i love it! It doesn’t have the insulated bottle pockets, but you can buy an insulated bottle carrier that matches the bag. the bottle pockets are huge and can easily hold two bottles or a large sippy. the changing pad is great. It has a lot of pockets for different things and a front pocket that is great for keys and the cell phone. The thing it is missing is an attatched wet bag (i just use a gallon sized ziploc and use it until it’s trashed). It’s easy to keep organized and it’s cute!

I agree with Amy. About 4 years ago I bought an Eddie Bauer messenger style bag that fits your description, probably mostly (i am going by memory here – insulated bottle holder, wet bag, nice changing pad, spacious inside, decently looking. But i don’t see them in Babys’R'Us any more. Now they have totes that are similar in description. Maybe worth checking out?

My Fleurville does almost everything you want. You don’t mention budget, but these are pricey. I would likely not have bought mine (it was given to me) and yet I’m so glad to have it. It’s stood up well through both my kids. So, if you buy one you can use it for your next baby!

For durability I love my Maggie Bags diaper bag. Durable, eco friendly and stylish.

Has everything you mentioned. Although, the wet bag isn’t real large.

You could probably get someone on Etsy to make one to your specs. Wouldn’t an attached wetbag get really smelly? We wash our wetbags with the dipes. Anyway, if someone were doing a custom, they could make a snap-in wetbag which I think would solve your concerns about losing it, but make it easy to clean. Also, now that my “baby” is 2, sometimes I just take the wetbag with a clean dipe and a few wipes inside – so if you had a snap out one, you’d have that option in the future for quick errands.

I think you are looking for a Ju-Ju-Be bag – maybe a BeAll. http://www.ju-ju-be.com/products/messengers.html

There is a great forum at the site too, great for buying used bags and for getting recommendations from been there/done that mamas! :)

GoGaga Bag (http://www.gogagalife.com/slide.aspx). Awesome bag.

We’ve been pretty pleased with DiaperDude (http://www.amazon.com/Diaper-Dude-Messenger-Bag-Black/dp/B001AYXM82/ref=sr_1_2?ie=UTF8&qid=1289705363&sr=8-2). They have some other models that might be worth checking out, too.

I’m definitely going for a JuJuBe with this next baby! I 4th the recommendation! They’re very innovative and seriously have pretty much thought of everything when making these bags!!! Slightly more diaper bag like than some of the other options out there, but at least they have cool prints, several carrying options for each bag, and now that I have a 3 year old and a little one on the way, I understand the need for having 2 hands available so one that quickly converts to a backpack, a type of diaper bag I used to despise, is very intriguing!
