The black/dark gray Photo Active BP 300 AW Backpack from Lowepro has a lightweight 210-denier triple ripstop nylon top and a high-abrasion 500-denier polyester bottom for rugged durability. The backpack is useful for travel and outdoor enthusiasts, is made from IP 6/7-rated DryZone materials, and has an all-weather cover for extra protection against inclement weather. The interior has a QuickShelf divider system which can be configured to hold a DSLR, a 70-200, and a 300mm prime lens plus personal gear in the top compartment. All your equipment can be dispatched quickly via the three easy-access zippered entry points, and there are two integrated side pockets for holding a water bottle and/or a compact travel tripod. The rear CradleFit compartment holds a 15" laptop or a 3L hydration system, and the front of the backpack has attachment points for trekking poles or a monopod. Furthermore, the ventilated ActivZone back panel keeps you cool and dry during those hot summer days.
