Tamrac’s Velocity Series has a unique design that allows them to be carried comfortably like backpacks, but they don’t need to be removed to access photo equipment. The Velocity 7z Photo Sling Pack is an ultra-functional sling pack designed for a DSLR with a zoom lens attached up to 6? long, a few additional small lenses, a flash and accessories. These sling packs are also customizable with Tamrac’s Modular Accessory System™ components.
