Coghlans Disposable Hand Warmers are ideal for instantaneous heat in cold weather and are suited for warming cold hands when walking and hiking. In emergencies they can provide a quick source of heat for people with injuries.
These hand warmers are manufactured from iron powder, salt, water, sawdust, and activated carbon, contained within a air permeable Tyvek pouch. Once exposed to air, the iron powder reacts with the oxygen to form iron oxide (rust), releasing heat in the process.
To use, remove the hand warmer from its plastic cover and massage/shake several times to circulate the air, allowing a few minutes for the pack to warm up. Ideally they want to be placed within a pocket or glove to help retain the heat.
*Please Note: Supervision is required when using with children, the ill or disabled.
