Mycoal Warmpacks are the ultimate in lightweight heat sources, the essential accessory for outdoor sports and activities in cold weather, providing hours of continuous warmth, anywhere, anytime. The warm packs are self-heating and therefore totally portable, as well as clean, safe, non-toxic, light and easy to use.
To use, simply remove sachet from the air-sealed pack, and within minutes, the warmer will generate comforting, warming heat.
How they work:
When iron rusts it gives off warmth called oxidizing heat, but you cannot feel this heat because its oxidizing rate is too slow. If this is speeded up, more heat is produced. This is the principle behind MYCOAL WARM PACKS. The warmers are activated by removing them from their protective airtight packaging to expose them to air. The blended ingredients of iron, salt and water, combined with the oxygen from the air, causes the rapid oxidization of the iron particles. This reaction produces heat. The heating temperature and duration are controlled by the amount of air ventilation, which passes through the many tiny holes on the inner packets. The duration of the reaction is finite (7 hours of heat).
