The Go packable backpack from Aer definitely provides more than most packable backpacks.
Other Bags to Check Out:
At first glance it looked weird. Then I used it for a couple days. Good god does this bag do it all well. Seriously, so much organization, so well built.
Ok, these bags from Nomatic are chock full of pockets. There are 2 different bags: the Travel Pack expands up to about 30L, perfect for short trips and minimal travel. The Backpack is 20-24L daily carry. Both are very sleek and, like I said, so many pocketzzz!
The Simple Office bag from Qwstion is an excellent convertible briefcase/backpack with organization and aesthetics that fit many modern city folks.
The Mercator from Cecilia is an absolutely gorgeous, hand crafted backpack with loads of organization, customizable photo and tech storage and great external access.
The Aer Duffel Pack is not the tool for every job, but for particular uses it just might be perfect for you.
