The Tamrac 5765 Velocity 5x Photo Hip Pack Convertible (Black) is a 600 denier PolyTek bag made to hold a digital or film SLR with zoom lens attached (up to 5.0 long), additional lenses and a flash. Inside the main compartment, the camera with lens attached is suspended on two vertical, foam-padded dividers. The bag converts from a shoulder bag to a hip pack with the Tuck-A-Way hip belt. The cinch straps on the hip belt help stabilize the pack. There is a Quick Flip Top that opens away from the body for easy access to the gear. The front pocket has organizer pockets inside, to keep a mobile phone, PDA or photo accessories within easy reach. The bag has a Memory Battery Management System that uses red flags to identify available memory cards and batteries from ones that are used up. The case uses the S.A.S. (Strap Accessory System) and M.A.S. (Modular Accessory System) products to customize bag.
