The Velocity 9x - Pro Sling Pack is the largest version of the popular sling packs. It holds a pro digital or film SLR with a grip (such as Canon's EOS 1D Series or Nikon's D2 Series) and a 70-200mm zoom lens attached. Inside the main compartment, the camera with lens attached is suspended on two vertical, foam-padded dividers that are internally reinforced with rigid plastic. The Velocity 9x can be carried comfortably like a backpack, but when swung around to the front, the secure zippered Quick Flip Top opens away from the body for fast and convenient access to camera gear. A well-padded sling strap comfortably distributes the weight, but need not be removed to quickly access photo equipment. A Tuck-A-Way waist belt allows the Velocity 9x to be used comfortably during vigorous activities such as hiking or biking. The front pocket has organizer pockets inside to keep a mobile phone, PDA or photo accessories within easy reach. It also features Tamrac's US-patented Memory & Battery Management System that uses red flags to identify available memory cards and batteries from ones that are used up. A pocket inside the lid stores filters and lens caps.
