Heatmax Hand & Body Warmer (40 Count)

I don't know how these work, but they're amazing. If you're choosing between this and the hand-size version, keep in mind that these last almost twice as long. The downside is that you'll use them up faster because you need one for each pocket. Sometimes they have a tendency to get too hot though, which isn't a problem for me, but I wouldn't give them to young kids or elderly, and I definitely wouldn't fall asleep with one touching your skin. Also, they really do last around 20 hours in case you're skeptical!

This is a favorite product of mine. It makes going through the winter so much cozier. I just love them. One in each pocket, and I'm happy all day.

This is a fantastic product for people who work outdoor during the cold nights, also great for camping or hunting at night.. The pack will keep you warm for a very long time.. It worked for me during my last boy scout camping. The temperature was 32*F during the night, but I used several packs to warm me up.. It lasts very long time, more than 15hrs at least.

I use 4 of these warmers every time I go out deer hunting in the cold. I generally sit for up to 7 hours at a time, and when the air temperature is below 30 degrees, these are invaluable in allowing me to stay on the deer stand. I really like the fact that they produce 18 hours of warmth, as I am often in the field for over 12 hours at a time.

I use one in each boot, right under my toe area, and in the palm of each hand. These are the areas that get cold when you are outdoors in cold weather, and if you can keep these areas warm, your entire body will feel warmer. I sometimes place on on the back of my neck on really cold days.

I like the 18-hour warmth produced by these warmers. I have used other warmers, and have always come back to these. I think they are the best on the market.

They do come in different sizes. I select the larger size because I want more warmth rather than less. The larger size has not proved to be an issue in terms of bulkiness. I suppose if you wear really close-fitting boots, you may want to use the smaller sized version. I use pack boots and they fit easily in the toe area with room to spare. Even in my gloves, the warmers do not interfere with the operation of my rifle.

I could not hunt as long without these warmers. They have become an essential part of my deer hunting gear. Highly recommended for hunters, and of course ice-fishermen and women.

These things are awesome,these and the smaller hand warmers. I have been a mailcarrier for 18 years and the handwarmers are perfect for warming up cold hands. They stay warm all day! I only recently discovered them. I wish I had found them sooner!
