The body warmers heat up in just minutes, and can prove to be a very useful addition to any emergency survival kit. The Body Warmer is air activated, so warming begins by the simple opening of the package. They last for 16 to 20 hours and heat up to 150 degrees with an average temperature of 130 degrees. Place within your sleeping bag or under clothing for optimal results.
To use across multiple days or activities, store the heat pouch in an airtight bag. The chemical reaction producing the heat cannot continue in the absence of air, so it will be stopped and will not resume until the bag is opened.
