Hot Hands Hand Warmers are single use air-activated heat packs that provide everyday warmth and are ideal for keeping your hands warm when the temperature gets cold. These warmers provide safe, natural heat, so you can enjoy the great outdoors during those harsh winter months. HotHands Hand Warmers easily fit inside your gloves or pocket to provide long-lasting, soothing warmth.
First, I'll agree with one reviewer who said these do not heat up quickly and do not get very warm. I've worked around some things, as I rely heavily on these to keep my hands from freezing as I work to take care of horses, daily, no matter how bad the weather, sometimes as low as 20 below zero. Before I leave the house, I slip these into the microwave for a few seconds. You'd have to test yours to figure out the timing. This gives them a boost and they are immediately warm. In severe weather, I sometimes use two pair at a time. I start out with a silk glove liner, put one in my palm, slip on a cotton glove and put one on the back of my hand, (or in the silk glove) before putting on my final and outer glove. These warmers will last for about ten hours unless, if you are out for a couple of hours at a time, off and on like I am, you can make them last longer by sealing them tightly in a plastic bag (sandwhich). With no air, the heating stops. I can make one pair last for possibly three days. I keep a marker handy and just make a little slash mark for each hour I've used them. I know this sounds like a lot of work, but it's the only thing that makes them affordable for me. As one reviewer said, they use them for a family member with Raynaud's Syndrome. I have that too. Keeping my hands from freezing is a challenge. I sometimes resort to the foot warmer's with the higher temperatures.
Hand warmers work through the magic of rust..yes rust. Iron in the pack when exposed to air starts to oxidize and its sped up by Salt in the packs as well. Carbon in he packs spread the heat around and vermiculite which helps the heat from escaping to fast. There are other things in there but that is the basic magic of hand warmers.
Sometimes I would have to open another pack just for a few hours of heat. Like I said i'm out in the winter cold for 8 to 10 hours a day. Don't think these are going to keep your hands super warm like you are holding them over a fire...they wont. However they will help you from getting frostbite. I also keep several of these in my Tahoe and my wife's car for emergency purposes...Always be prepared, folks. They are cheap and could help save your life in dire situations specially if you have small children.
If you are wanting more of a distributed heat and are in a situation where you can hold a warmer, they do make electrical hand warmers that run on rechargeable batteries.
