The Thinktank Airport Acceleration v2.0 is a roughly carry-on sized bag designed to hold a fair bit of camera equipment. I say "roughly" because with the backpack straps stowed, it takes a bit of squishing to get it down to the standard 9 inch carry-on thickness. That's right: this carry-on bag is also a backpack, if you hate yourself. Holds a complete multi-camera setup, including very long lenses: interior dimensions are approximately 17x33x45.
Please note: This bag was designed to carry-on specifications at the time of its manufacture, but we can not guarantee that it will be accepted as carry-on luggage. Be sure to check with your airline before departing.
