The Ergodyne N-Ferno Toe Warming Packs are self-contained packs that add heat anywhere when exposed to air. There’s nothing like the great outdoors in winter. But when you’re cold, being outdoors isn’t great at all. N-ferno warming packs help you stay warm so you can stay, play, and work outside while achieving peak performance in total comfort. If warming time is not completely exhausted, N-ferno warming action can be preserved for several days by packing them in an airtight container, such as a zip-seal polybag. N-ferno products are packaged in their own reusable heat action preserving zip seal polybags, for your convenience.
How They Work:
N-ferno Warming Packs literally “run on air”. Each soft, lightweight pouch contains a mixture of iron powder, water, vermiculite, cellulose, activated carbon, and salt. Once the outer package is opened, an oxidation process takes place which causes a safe, natural reaction to release heat. N-FERNO Warming Packs utilize the same technology as used by the National Ski Patrol, explorers of the Arctic and Antarctica, and military forces around the world.
