The Tamrac MX5352 M.A.S. Modular Accessory System Medium Raincover is made to fit some of the Tamrac back packs. The Tamrac photo backpacks are made from water-proofed materials and have giant rain flaps, so in general, they don't require a rain cover. When extra security is desired, MX5352 Raincover provides it with a double waterproof-coated PowerGrid nylon that protects everything except the back of the backpack and the harness. Folded in their pouch, they attach to any of the M.A.S. backpack attachment points
