So many uses when you otherwise don't mind getting outside in the cold. Keeping your hands warm can be so important with having fun outside. These work great. Often last longer than the specified time, because that will depend on how much oxygen they get to react with. Works great, every time we use them. Can't beat the best price around. When they go on sale, bug more than you thought you needed. They can last a long time in storage. I had some that sat unopened for 4-5 years and still worked great.
