The Realtree AP Snow Lens Cover for the Nikon 18-105mm f/3.5-5.6G Lens from LensCoat is a 100% closed-cell neoprene coat that protects the lens from bumps and scratches. It is useful for nature and outdoor photographers, as well as sports shooters and photojournalists. The cover helps break up the shape of the lens, making it less noticeable to wildlife. It also provides a thermal barrier, protecting your hands from cold lens surfaces in lower temperatures. The cover is waterproof, providing protection to your lens in wet conditions. This version is white and covered with a subtle pattern of leaves and branches to help camouflage the lens when you are shooting in snowy conditions.
