This Polar Mitten Camera Case from Porta Brace is a thick, padded cover you can use to keep your camera warm, dry, and functioning properly in cold weather. It will also minimize condensation when you bring your camera indoors from the cold. Tested to -50°F, it can be used handheld or tripod mounted. The fleece-lined sleeve keeps your hand warm during filming. The high-loft, heat-reflective insulation accepts air-activated warmers that keep the camera warm, and four warmers are included with the Polar Mitten. The insulated lens cap protects the front element of your lens.
