The CalorPad body warmer provides 24 hours of natural heat after opening! You are going skiing, snowshoeing or in a cold environment, you have to sleep outside, don't forget your body warmer. Lightweight, barely 50 g but essential for your comfort and safety in extreme conditions. How it works ? When exposed to oxygen in the air, the iron filings inside the pocket begin to oxidize, creating a rapid rusting process which in turn produces waste heat. The salt acts as a catalyst, while the carbon helps disperse heat evenly. Vermiculite acts as an insulator that prevents heat from dissipating too quickly.
