The Airport TakeOff rolling backpack quickly converts from backpack to rolling case - straps can be instantly tucked away, or zipped completely behind the back panel - so if the going gets rough you can easily strap it on your back. It holds a large outfit, including a lens up to 400/f2.8 size, and a 17" laptop (an Artificial Intelligence case will fit in the front pocket to give extra protection). A front cable and lock to secure the laptop is supplied, and an all-weather cover.
