Jon-e handwarmers: GREAT
A great handwarmer for hunting or any outdoors activity. Way warmer than those disposable packets, and cheaper in the long run. Burns for hours.
The handwarmer itself looks like an over-sized zippo lighter and comes with a nice carrying sleeve. New, $16.00 ppd.
Fuel comes in 16 oz. cans, $7 per can, ppd. Two or more cans, $6 per can. The handwarmer also uses lighter fluid, although I've never tried it, so I don't have a comparison to the Jon-e fuel.
Get 'em now, guys, it's COLD out there!
