I use these warmers not only in gloves or pockets during severe frosts, but I've found an unusual use for them in airsoft, especially when the temperature drops below zero. When using a replica powered by green gas, I have to take into account the reduced gas pressure in the magazine when it gets cold, which negatively affects the performance of the replica and can sometimes lead to more serious problems – after a dozen or so shots the gas can cool down too much and the valve will stay open because the slide doesn't return fully to the rear. Thanks to these inconspicuous pouches, which I stick to the sides of magazines and place at the bottom of the pouch, I can play normally even at -10°C, whereas without them, below -5°C there's already a risk that the replica will stop working. P.S. The warmers activate in contact with oxygen, so to make them heat up faster after opening the package, it's worth giving them a good shake.
