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" long, 3-4 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 Memory & Battery Management System (patent pending), 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.
