reusable hand warmer

[1azarus]

A bag or bottle of water will hold as much heat as well as any of these products. The thing with the hotsnapz is you can make it become hot when you want to (unless it goes off prematurely).

...so, i could just boil water, put it in a nalgene, and put it in my sleeping bag like everybody else? where's the fun in that? i did just get a Skratch Labs Purist Hydro water bottle and i was wondering how warm the water could be that i can safely put in it. I did just email them to find out.

The king daddy of all hand warmers is the Jon-e. They run off of lighter fluid, and will stay hot for up to 12 hours. They don't use a flame, but instead use a chemical reaction between the fuel, oxygen, and a platinum catalyst. they will get hot enough to burn you, which is why you leave it in its felt pouch. Those suckers get the job done! A little on the heavy side for lightweight backpacking.

They don't make them any more, but you can get a good one on ebay for $20-30. Try to find one with a burner that it in good shape.
