"I just got back from a week-long trip to England. All my clothes were in checked luggage, everything important to me stayed on my person.
My Tom Bihn Ristretto held:
13" MacBook Air
A lithium-ion USB charger
4 AC adapters and cables for all of the above
A set of in-ear headphones in a padded case
A Fluxx deck
6 medicine bottles
All my travel documentation
Around 15 keys between two keyrings
My work badge
A paperback book for landing/takeoff
...and was comfortable enough to walk several miles around airports, train stations, and London strapped over my back with an Ultimate strap. It even stowed under the airplane seat with enough space left over for my feet.
Thanks for making such an awesome bag. You literally made my trip."
