The Expedition 5x is the perfect mid-size pack for a wide range of photo equipment. The main compartment is completely foam padded with numerous adjustable, foam-padded dividers to protect digital and film SLRs with lenses attached, 4-5 additional lenses, and a flash. A foam-padded front pocket with a water-resistant zipper holds most 12" screen laptops. Two "wing" accessory pockets with water-resistant zippers organize and provide quick access to important accessories without disturbing the photo gear. These "wing" accessory pockets also feature Tamrac's patented Memory & Battery Management System that uses red flags to identify available memory cards and batteries from ones that have been used up. A tripod is carried between these pockets with Tamrac's QuickClip tripod attachment system. Inside, the camera with a long zoom lens attached is suspended on two vertical, foam-padded dividers that are internally reinforced with rigid plastic. A restraint strap holds lens firmly in place. A Dual-Hinge Divider System allows a second SLR to be carried with a lens attached. Two Windowpane-Mesh pockets inside the front flap visibly organize filters, film and other accessories. A plastic, foam-padded platform in the bottom provides shock protection while the LockDown Rain Flap protects the zipper from the elements. The state-of-the-art harness system with Dual-Density Comfort Pads provides maximum carrying comfort while Air Flow Channels help keep you cool and dry during extended use. The pack is also equipped with an adjustable waist belt and an expandable sternum strap. Internal Dimensions: 11W x 5.5D x 13.5H. External Dimensions: 12.75W x 10D x 16H. Weight: 4 lbs. 8 oz.
