Camo Neoprene Cover.
Lenscoat part number TC500VRBK.
The black TravelCoat For the AF-S Nikkor 500mm f/4G ED VR AF Lens from LensCoat is a 3.0mm thick, shock-absorbing, closed-cell neoprene lens cover that is custom tailored to fit without lens hood. It is designed to fully protect the lens when not in use, without the need for a more comprehensive lens case. It allows more valuable room for packing and storage. The coat slides over the lens, and closes with a secure touch fastener. This version is matte black to better blend in where desirable. Or, it can be used just for its protection value.
