Best Diaper Bag for long trips

Just wanted to get everyone's opinion on the best diaper bag for long trips. We will be flying to CA in July and I have 2 kids in diapers - so I need a lot of space in the diaper bag - but it needs to be easy to carry and fit under the airplane seat. Thanks!

Hi there! I fly to CA and other places a lot w/ my 8 month old. We figured out that this last flight home was his 16th! That said, my normal diaper bag wasn't cutting it for our trips. I need my carry-on to hold more than baby stuff (magazines, laptop, etc.) I just picked up a bag by Nike at Sports Authority at 20% off.

Here's a link that shows it, though I don't see the discount online: http://www.sportsauthority.com/product/index.jsp?productId=2568311&cp=&sr=1&origkw=nike+bag&kw=nike+bag&parentPage=search

I love it! It's super easy to carry, and I can fit my (on the smaller side) diaper bag right down in it along with everything else I need. That way I don't have to unpack my diaper bag for the trip, and I still have it to take on short outings once we're at our destination.

I'd go to the store at La Salle and Ontario to get the discount. I think they also had it in red and gray in the store. Good luck traveling!

I love my Mia Bossi Caryn bag. It has been on many flights (about 12) with our 10month old. It has pleny of pockets and plenty of space. It fits under the seat and the straps can be rearranged to hang off a stroller(less to carry). http://miabossi.com/

Good luck and have fun!
