Zing LPBK1 Large Drawstring Lens Pouch (Black)
This multipurpose Zing camera lens pouch features a stretch-Lycra top that  allows the drawstring to slide smoothly and cinch tightly, along with a reinforced belt  loop webbing. As a result, you can safely and securely carry a large lens or other  accessory outside or inside your camera bag. The pouch, which measures 4.5 inches in  diameter and 9 inches long, sports a black neoprene body that's durable and soft, with a  black top hem that's color coded to differentiate your various lenses (other hem colors  included blue and purple). And thanks to the plastic clip on the side, it's a breeze to  attach the pouch to the outside of a camera bag or backpack for easy access. The Zing  pouch weighs 5 ounces and is backed by a one-year warranty.
