The Realtree Max5 TravelCoat Lens Cover for Nikon 400mm VR Lens from LensCoat is a 3.0mm thick shock-absorbing closed-cell neoprene lens cover that is made to be used with the lens hood in reverse position. 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 simply slides over the lens, and closes with a secure touch fastener. The Realtree Max5 is a detailed camouflage pattern that features cattails, millet, milo, corn stalks, sunflowers, oak and maple leaves, cedar and oak limbs, plus a variety of other plant life.
