The Lens Coat Lens Cover for the Canon 70-200mm f/2.8 L IS II lens protects the lens with a 100% closed-cell neoprene coat, offering your valuable equipment some resilience to bumps, jars, scrapes & nicks. Easy to install & remove, leaving no residue on the lens, Lens Coat Lens Covers are ideal for nature & outdoor photographers, & for sports shooters & photojournalists as the neoprene provides a thermal barrier, protecting your hands from cold lenses in lower temperatures. The Lens Coat Lens Cover features clear plastic windows over the main lens dials & controls to ensure that using & mounting the lens isn't hindered in any way by having the Lens Cover attached.
