Brrrrr, cold hands in winter in the city or on the ski lift? The Thaw hand warmer provides 10 hours of natural warmth after opening! A small 45g pack to always keep in your backpack. Thaw hand warmers are very popular in winter with people suffering from Raynaud's syndrome. How do they work? When exposed to atmospheric oxygen, the iron filings inside the pocket begin to oxidize, creating a rapid rusting process that in turn produces residual heat. The salt acts as a catalyst, while the carbon helps to disperse the heat evenly. Vermiculite acts as an insulator, preventing heat from dissipating too quickly.

• Weight: 55 g per pair
