The Realtree Max5 Lens Cover for the Canon 800mm f/5.6 IS Lens from LensCoat wraps the lens in a 100% closed-cell neoprene jacket, offering protection from bumps, jars and nicks. This coat allows you to blend in with your surroundings. It is useful for nature and outdoor photographers, as well as sports shooters and photojournalists. The Realtree Max5 camouflage pattern offers maximum effectiveness in open terrain. The pattern incorporates cattails, reeds, cane and grasses to blend into flooded marshes, plus corn, wheat, oats and sunflowers to hide you in open fields.
