DSPTCH hand-makes bags here in the USA and the Travel Pack is a great example of the kind of extremely durable designs they put together.
Other Bags to Check Out:
A really solid feeling bag with lots of pockets both inside and outside the bag and enough capacity for the minimal traveler.
Miles the Duffel 40L from Millican is a sturdy little companion for travel (so long as you don't have to walk long distances with your bag!).
The Setout Laptop Backpack from Tortuga is an excellent bag for minimal travel AND daily carry.
The Monolith Weekender from Heimplanet is one of my favorites because it is very durable and simple. Carries all your shit, and comfortably!
The Akra backpack from Arcido is designed to be a minimal travel bag with clean looks and plenty of organization and pockets.
