How do I re-use my air-activated warmers?

Each set of Ignik warmers comes in a resealable AirBarrier™ pouch, which you can use to extend the lifespan of your warmers. If you come in from the cold while your warmers are still working, you can store the opened warmers in the AirBarrier™ pouch and reuse them up to 72 hours later. AirBarrier™ keeps the air out for more reliable heat and is 100% Recyclable.
