The Case Logic SLRC-205 SLR Sling (Black) is a nylon bag with a memory foam interior that helps protect the delicate LCD screen. The SLR Sling wears like a backpack but allows for instant access to the SLR and accessories. A hammock system suspends the SLR above the bottom of case, providing impact protection. There is a large zippered compartment (7.5 x 3.75 x 3.0") that stores an additional lens or flash. There are 3 zippered pockets that store memory cards and other small items. An industrial strength hook and loop strap can carry a tripod. The adjustable shoulder strap with waist strap prevents the sling from jostling around during activity.
