It is a very large bag with several compartments - Most important to accommodate a DSLR camera with a 70-300 and mounted 6 modular slots for flash or objectives, - Above a handy tote for a good hike. - 1 Net on the side to slip a bottle of water, - 2 large pockets up and down, - 1 storage for a laptop up to 15.4 inches.
The port is very comfortable for short walks just like the big hike through a lap belt.
