The Canon white Lens Cover for Canon 70-300mm f/4-5.6 Lens from LensCoat is a 100% closed-cell neoprene coat that protects the lens from bumps and scratches. It is ideal for nature, outdoor photographers, sports shooters, and photojournalists. It also provides a thermal barrier, protecting your hands from cold lenses in lower temperatures. The cover is waterproof, providing protection in inclement weather.
The Lens Cover is easy to install and remove, leaving no residue on the lens. It will also help you preserve the resale value of the lens by protecting it from dust, dirt, and other contaminants.
Please note that the Lens Cover cannot cover the fixed portion of the lens barrel due to the manner in which the lens barrel extends/retracts, leaving a small section exposed when the lens is fully extended.
