Yaktrax® Hand Warmers are a safe, easy, and all-natural solution to cold hands. Once opened and exposed to oxygen in the air, these disposable but environmentally-friendly warmers begin working in just minutes. Slip them into a pair of gloves or jacket pockets and create a cozy cocoon for your hands that lasts up to 8 hours. Yaktrax Warmers are the ideal choice for outdoorsman, winter athletes, spectators, and anyone who works or plays outdoors.

How it works: When exposed to oxygen in the air, the iron filings inside the pouch begin to oxidize creating a rapid rusting process which in turn produces residual heat. Salt acts as a catalyst, while carbon helps to evenly disperse the heat. Vermiculite acts as an insulator that helps prevent the heat from dissipating too quickly.
