Avoid getting ice-cold hands when you're outdoors during the winter months. Cold hands make many activities difficult, ranging from winter sports to simple things like typing a message on the phone. The hand warmers are not only handy for keeping your hands warm, but can also improve your comfort and efficiency in many everyday activities. Whether you're out on the ski trails in the mountains, or sitting on a hunting pass and waiting.
The Zippo Hand Warmer is completely odorless and smokeless, making it comfortable to use even indoors or in enclosed spaces.
Zippo also has some battery-powered hand warmers (which are charged via your computer's USB port)
