Warmth on Demand! from Jim Dandy...
Long lasting hand and body warmers. These are the best type of
chemical pack to slip into your boots because they remain flexible.
Some other types turn into a rock as they cool making walking very
uncomfortable.

Remember that an ounce of prevention is worth a pound of cure. Keep
a couple of these in your pack. They can save the day if  the weather
turns colder than you'd planned!
