Features yaktrax hand warmers (pack 10 uds)
Yaktrax & reg; hand warmers are a safe, easy and totally natural solution for cold hands. Once opened and exposed to oxygen in the air, these disposable yet eco-friendly heaters start working in just minutes.
Slip them into a pair of gloves or in the pockets of a jacket and create a cozy cocoon for your hands that lasts up to 8 hours. Yaktrax heaters are the ideal choice for outdoor enthusiasts, winter athletes, spectators, and anyone who works or plays outside.
When exposed to oxygen in the air, the iron filings inside the bag begin to oxidize creating a rapid oxidation process that in turn produces waste heat. The salt acts as a catalyst, while the charcoal helps to evenly disperse the heat. Vermiculite acts as an insulator that helps keep heat from dissipating too quickly.
