The Realtree Max4 HD TravelCoat for the AF-S Nikkor 600mm f/4G ED VR Lens from LensCoat is a 3.0mm thick, shock-absorbing, closed-cell neoprene lens cover that is custom tailored to fit with the lens hood in reverse position. It was 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. The Realtree Max4 pattern offers effectiveness in open terrain. The pattern features cattails, millet, milo, corn stalks, sunflowers, oak and maple leaves, cedar and oak limbs, plus a variety of other plant life.
