The Expedition 4 is a compact, feature-rich pack for any photographic outing. This high-mobility pack offers foam-padded protection and quick access to an SLR, lenses, flash and accessories.
The main compartment is completely foam padded with numerous adjustable, foam-padded dividers to protect a digital or film SLR, 4-6 lenses (including a 70-200mm zoom), and a flash. The camera with a zoom lens attached is suspended on two vertical, foam-padded dividers that are internally reinforced with rigid plastic. A restraint strap holds the lens firmly in place. 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 a LockDown™ rain flap protects the zipper from the elements. The front pocket holds extra gear and features a water-resistant zipper. 

“Wing” Accessory Pockets 
New Dual "wing" pockets with water-resistant zippers organize and provide quick access to important accessories without disturbing your other gear. These "wing" pockets also feature Tamrac's U.S. patented Memory & Battery Management System™ that uses red flags to identify available memory cards and batteries from ones that are used up. 
QuickClip™ Tripod Attachment System
A tripod is cradled (centered and balanced) securely between these pockets with Tamrac's QuickClip™ tripod attachment system while the lower, plastic-reinforced Tripod Foot Pocket holds two tripod legs secure.
The Harness 
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 for finer adjustments. The harness features "D" rings that accept Tamrac's optional backpack camera strap (Model N-11).
M.A.S.™ and S.A.S.™ Compatible
Strap Accessory System™ (S.A.S.™) and Modular Accessory System™ (M.A.S.™) attachment slots on the pack provide a convenient place to carry Tamrac's optional M.A.S.™ and S.A.S.™ products. Four SpiderTabs™ provide additional attachment points for expedition equipment or extra clothing.
