PortaBrace Heat Factory Polar Heat Packs are a soft lightweight pouch containing a mixture of iron powder, charcoal, salt, sawdust, and vermiculite. When the PortaBrace Heat Pack is exposed to the air, an oxidation process takes place that generates heat up to 130 degrees for more than 8 hours. You can halt the process for later use by simply inserting the Porta-Brace Heat Factory Warmer into a heavy-duty zip lock bag. Contents are biodegradable. Unopened, Porta Brace Heat Factory Case Warmers have a shelf life of three years. Place the heaters in the mesh pockets of your camera cases, near the lens and battery, ideally. Toss these handy case accessories inside Porta Brace camera cases to keep things warm when not in use. These PortaBrace case accessories keep your hands and feet warm, too.
