The RIG-FS7XLOR has smooth-rolling, off-road wheels with ball-bearings and solid steel axels for added strength. The wheels are also removable to help prevent damage during air-travel. This rugged case is constructed using long-life materials including 1000-denier Cordura nylon and solid steel clip rings. Reversed zippers and a slip-not anti-skid waterproof bottom panel are used for increased water-resistancy and durability. The 11" interior height allows for a variety of equipment configurations and the easy-open, quick-draw design means you'll never miss the shot. There are front and back slip pockets for carrying SD cards, documents, cords, and white balance cards. The 2 side pockets are perfect for batteries, extra flashes, and cords. The interior of the case is made using a copper-colored Veltex that contrasts against camera and lenses for clear visibility of the case contents. Completely customize your interior setup using the positionable interior divider system, including 1 horizontal divider, 1 padded divider pouch, 1 padded 7-inch lens cup / storage pouch, 1 padded 4-inch lens cup / storage pouch, camera tie-down, and divider camera "cradle". Comfortable genuine suede shoulder strap and handles are included.
