I have the 206 model, has a spot for a 15-16 inch laptop, Large compartment for slr gear, side pocket for small stuff, front pocket for small stuff, and nice straps for tripod on the side. Bottom is large flexible plastic for water resistance. very tough outer shell with smooth working zippers and padded arm straps. Got mine for a song at Sams club, went back and got another one. Lots of very customizable dividers. could fit two bodies and 3 lenses plus cards/battery/charger. Right now I have canon 5dII + lens + flash + stuff in one and 7DII + 2 lenses + flash + stuff in the other with plenty of room for more.
