Porta Brace BK-4BOR Extra-Large Rigid-Frame Backpack with Off-Road Wheels

The BK-4BOR is large and still light. Its rigid-frame design builds a solid structure with less weight than a traditional rigid frame, without giving up the level of protection that frame is there to provide. The large padded interior suits big camera setups: HDSLR rigs, several compact HD cameras, camera and mattebox rigs, and other large field equipment.

Underneath are smooth-rolling off-road wheels on ball bearings with solid-steel axles for strength under load. The wheels come off to prevent damage in air travel, so the pack goes back to being a backpack when the case is checked or stowed.
