DISQUS

This is a pretty old technology. I have one that is about 40 years old (no it doesn't have butterflies on it) and it works great. I use for skiing.

Theres one of these in my basement, been there probably 20 years. No butterfly though. And if I were to use it, I would hope that my friends, or strangers, would call me a nancy.

Umm, no thanks. Combustion is generally not a good thing when it occurs in one's pockets.

I have had multiple units (again with no butterfly) throughout the years. They have kept me warm on ski trips, snowmobiling, and hunting. They acually work great and are nothing to be afraid of.
