The realtree AP snow Lens Cover For the Sigma 150-500mm f/5.6-6.3 DG OS HSM APO 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. It also features a clear plastic window through which you can see the autofocus controls and distance scale. Another benefit of the cover is that is helps disguise the shape of the lens making it less visible to wildlife when you are shooting in the woods. This version comes in white and is covered with a subtle pattern of leaves and branches to help camouflage the lens when shooting outdoors.
