The POL-FS5 Polar Bear camera cover is designed to keep the Sony PXW-FS5 warm in cold weather. It features a black nylon fabric exterior, is heavily padded and built with high-volume insulation. The interior is lined with a phase-change material (PCM) that stabilises temperature and helps retain warm air in the camera compartment. Air-activated hand warmers can be placed inside the case to maintain interior temperatures in extreme cold conditions (Portabrace Polar covers have been tested down to minus 50 degrees Fahrenheit). The POL-FS5 can be used with a lens hood or a standard lens. The attached insulated lens cover protects the lens during transport and prevents condensation from forming when moving the camera and Polar Bear case from the cold outdoors to indoors. Hook-and-loop strips line the interior of the Polar Bear to position optional air-activated hand warmers (Portabrace Polar Heat Packs). Two hand openings at the lens and one near the viewfinder are closed by cotton cuffs that keep hands warm. The POL-FS5 features three sets of zips that make it easy to install and remove the cover. The fitted lower zip wraps around the tripod plate, preventing cold from entering when the camera is used on a tripod. - Keeps the camera in good working order at extremely cold temperatures - Interior pockets hold air-activated hand warmers for extra warmth - Can be used on a tripod or in shoulder configuration - Can be used with a lens hood or standard lens
