This Polar Mitten Camera Case from Porta Brace is a thick, padded cover you can use to keep your Canon XF100/XF105 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.
