Carry and protect 1-2 pro DSLRs and an attached 400mm f/2.8 lens in this black Pro Trekker 450 AW Camera and Laptop Backpack from Lowepro. It also fits 4-6 extra lenses, 2 flash units, a tripod or monopod, and a 15" laptop. Padded, adjustable, MaxFit System interior dividers enable customization. Additionally, a built-in rain cover provides protection from the elements.
Built for durability, the bag is made of high-density 630D Oxford nylon and has a 1000D Cordura base. The ActivLift System Harness for load-lifting support is ergonomic and breathable, and transfers weight from your waist to your hips for added comfort. You can also adjust the length to your torso. For extra support and storage, the backpack's removable lid doubles as a waist belt/pack with multiple pockets and a mesh-covered back.
