Asseri Handwarmer

Asseri Hand Warmer is an air-activated, self-heating hand warmer. A top product for cold deer hunting stands or ice fishing trips. Open the package, let air flow into the heat pad and place the pad where you want it. Remember to let the pad react properly with air: if you put it straight into a glove, the air usually does not circulate and the heating power of the pad is left unused. After use, the pad can be disposed of as mixed waste. At best, the pad produces heat for 12 hours, but in the Finnish winter the time is approx. 4-5 hours.
