F-Stop is known for their weather resistant expedition type back-packs. The Loka is an alternative product line that’s a bit smaller externally than the Satori (12×23×8.5 inches) so it fits easily in the overhead compartment. It is constructed of ballistic rip-stop nylon, high density foam, aluminum framing, and YKK waterproof zippers to survive bad conditions. Weighing only 3 pounds, its still has 37 liters of internal space.
Inside is a separate internal camera unit that is compartmentalized, padded and fully removable so no fumbling through your spare clothes to find your camera equipment. We send it with the default Large internal unit: plenty large enough for a professional-size SLR with 70-200 f/2.8 or larger lens mounted, 4 to 7 spare lenses, flash, backup camera, whatever.
It has a full padded harness with hip, shoulder, and sternum straps; numerous external pockets and attachment loops. If you’re going to do some serious hiking with your gear, this is the backpack you want. Although the picture above is the light gray model, we are stocking the olive green color.
