The Expedition 3 offers expedition-level performance in a compact photo backpack. This full-featured pack is perfect for holding most SLRs with a lens attached up to 7 inches long, 3 to 4 additional lenses and accessories. For maximum protection, the pack is fully padded with thick, closed-cell foam. A cinch strap keeps the camera in place while a large rain flap protects the main compartment zippers. Features include: QuickClip tripod attachment system with vinyl reinforced mesh pocket, front accessory pocket with Tamrac's U.S. patented memory and battery management system that uses red flags to identify which memory cards and batteries are available and which ones are used up, EasyGrip handle, inner windowpane-mesh accessory pockets, and padded backpack harness. Add Tamrac accessories to the strap accessory system (S.A.S) and modular accessory system (M.A.S.) attachment slots to customize this pack.
