The LensCoat Lens Cover is designed specifically for the Sigma 150-600mm f/5-6.3 DG OS HSM Sports lens. Its closed-cell neoprene construction helps protect the lens barrel from bumps, scratches, weather exposure, and handling impacts while providing thermal insulation in cold conditions.

The Realtree Max4 cover includes clear UV-PVC windows for the autofocus, image stabilizer controls, and distance scale. An additional cover protects the exposed lens section when zoomed out. It is suited to wildlife, nature, sports, and photojournalism applications.
