Ignik's Multi-use Warmers are designed as long-lasting, efficient heat. If you don't use all your heat, simply reseal your partially used warmer in the AirBarrier™ pouch and reactivate the remaining heat up to 3 days later. We believe that you should use all your heat. Also, the inside contents are 100% biodegradable and the packaging and outer are recyclable.

Our hand warmers reach a max temperature of about ~140 degrees F, with an average temp around 135 degrees F. The exact temperature will vary slightly depending on environmental conditions and the amount of air the warmer is exposed to. 140 degrees F is generally accepted as the high end of the range for safe and comfortable heat. For maximum comfort, we recommend using these warmers outside of a glove liner or other layer of clothing; or if your gloves have a zipper pocket, our warmers will fit nicely inside!
The short answer is, "probably". But it does depend on just how wet the warmers get.
The warmers generate heat via a chemical reaction which is catalyzed by air flowing through tiny holes in the pouch. A large amount of water can block the airflow to the contents of the pouch, impeding that reaction. The warmers will not work well, if at all, if they are submerged or totally saturated. On the other hand, light to moderate rain, or the amount of moisture that might be generated by sweat or a bit of snow melting on your gloves, is not likely to impede the function of the warmers significantly.
If your warmers do get very wet and it seems like they are not working adequately, drying them off and then giving them a vigorous shake should get them working, though they still may not give off quite as much heat as fresh dry ones.
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.
Our Air-Activated Warmers are effective for 3 years from the manufacture date, and the expiration date is marked on each package. The packaging is usually what fails first, so storing extra warmers in an airtight bag may provide added security that the warmers will work when you need them most.
