I'm looking for a bag that can be all (or most) of the following: laptop/messenger bag, airplane carry on, backpack, and diaper bag. My Google-fu is failing me, but I've come across the terms "travel bag" or "convertible". I like the look and durability of canvas bags or a similar type material. I'm not too big into leather, mainly because the good quality ones are mostly out of my price range (eg, Saddleback). I'd like to stay under $300, but can go higher for the right bag.
I'd love to be able to bring it to work (conservative-ish Big Pharma) with my laptop and papers, and on the weekends dump everything out and put baby stuff in it. It'd be great if it could it could be considered a "personal item" on an airplane and fit underneath the seat in front of me.
I want a backpack for when I'm carrying a lot of stuff; but I'd love to be able to convert it to a messenger bag if I don't want to look so backpacky.
Some examples of what I'm looking for:
I love the functionality and practiality of this, but something more stylish: Red Oxx Sky Train
That seems to be similar to the BagJack NXL Blue Travelbag
and Bag Lab Travel Bag
(need to scroll down for both)
I like the style of this, but I think it's a little too large and don't really like the tote-style bag: Sons of Trade Tactical Tote
(does putting the word "Tactical" in front of tote make it more manly?)
That company also offers this bag, but it is a little too small: Sons of Trade Nomad Knapsack
Not even sure if the back I'm looking for exists, but I'd love to see some options. Thanks!
