+1 for the Kata 466i/467i. I have worn out a 466i, using it for 3-4 day trips all over SE Asia. The laptop pocket is large enough for 3-4 clean shirts, and with the tiny size of the MBA 11", that should go in easily even with some clothing there. A nice feature of the 467i is that the divider between the top and bottom compartment can be opened, so that a small tripod, like one of the small carbon fiber models from Sirui, can be carried inside the bag, giving better weight distribution and not catching people, trees and eagles in cramped environments. Still, there's room for one body and five lenses at the bottom.
Other advantages are lots of small pockets and a bottom rooms that can be opened without cameras and lenses falling out.
I've suggested to Kata that they split the top/bottom divider so that it's easier to carry a tripod or a long telephoto lens inside the bag. They're considering the option. The only disadvantages with these bags are that the size of the top storage is limited, so no space for bulky clothing (for me, this is the city bag), and that the fabric towards the back wears out over time. There's also no air circulation between my back and the back of the bag, so it tends to get damp there, at least here where the temperature is mostly above 30 degrees C.
Very highly recommended :thumbs:
