29: Chrome Bravo Night
When you need to move a lot of gear from point A to point B without contributing to global warming by using an exhaust-spewing internal combustion engine, Chrome’s Bravo Night can get the job done.
This backpack boasts 20 liters (1220.5 cubic inches) of storage space, and you can nearly double that amount by unrolling its top flap. A second compartment can accommodate up to a 15-inch notebook.
Weatherproof denier on the outside and waterproof truck tarpaulin lining the inside keeps everything safe from the elements, and a large reflective panel on the back will ensure that motor-vehicle drivers see you at night.
