The BCB body warmer keeps your body warm when you are dealing with cold conditions. Usually these packs are used for comfort, but increasingly they are used in rescue operations where a survivor is trapped in a cold or exposed place. 
How it works:
Opening the sealed package causes oxygen to react with the bag. Within a minute, the bag will give off constant heat. Place the package in your pocket or anywhere close to your body where heat is needed and it will maintain a comfortable temperature of 50°C (Max 65°C) for up to 24 hours.
