The realtree max4 HD 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. Ideal for nature and outdoor photographers, and for sports shooters and photojournalists. The cover helps break up the shape of the lens, making it less noticeable to wildlife and makes it more comfortable to hold.
