The Manfrotto Advanced Tri-Backpack (Medium) provides 3 ways to store, carry and use your gear. You may use it in the backpack, sling bag or "X" position. Suitable for your pro DSLR with battery grip, attached mid-range zoom plus 3-4 additional lenses, flash and accessories; media card storage and space for 11" laptop or tablet.
The unique design of this pack allows you to access your gear even with the traditional backpack shape. In the backpack or "X" position with the straps across your chest you can easily and quickly swing the pack to your left or right side by simply releasing the quick release buckles. This means you don't have to remove the entire pack to retrieve gear. The pack is essentially divided in half with the bottom half for your photo gear and the top half for other items. It is slim and efficient in design.
The main camera compartment comes with modular padded dividers that give you the freedom to arrange the pack to suit your gear needs. The top compartment can also be used to store less frequently needed gear. There are two external zippered pockets that allow you to retrieve accessories without having to open the main compartments. The front of the pack contains tripod straps that can accommodate a small field tripod.
