The Velocity 6z Compact Sling Pack is designed for a compact DSLR (like Canon's EOS 600D/T3i or Nikon's D3100) with a zoom lens attached up to 5" long, another small lens, a flash and accessories. The sling pack design is versatile to carry like a backpack, but can be easily accessed by sliding the pack around to the front. The secure zippered Quick Flip Top opens away from the body for fast and convenient access to camera gear. A well-padded sling strap comfortably distributes the weight and allows the pack to be swung around to the front for camera access without having to remove the pack. The front pocket has organizer pockets inside to keep a mobile phone, PDA or photo accessories within easy reach. It also features Tamrac's U.S-patented Memory & Battery Management System that uses red flags to identify available memory cards from ones that are used up. A pocket inside the lid stores filters and lens caps. Add optional Tamrac accessories using the attachment slots for our Modular Accessory System (M.A.S.) products to customize this sling pack.
