The LensCoat Lens Cover for Canon 400mm f/2.8L IS Lens is a 100% closed-cell neoprene protective cover designed to shield the telephoto lens from bumps, nicks and harsh outdoor conditions. Its waterproof construction also provides a thermal barrier for handling the lens in cold environments.

The forest green camouflage pattern helps reduce the lens's visual profile in wooded surroundings. Clear UV-PVC windows maintain access to AF/IS/VR controls and the distance scale, while the red-dot alignment opening supports mounting without removing the cover. It is suited to wildlife, nature, sports and outdoor photographers.
