We used these back in the 80's when surfing/windsurfing/snow skiing.
I gave my last one away to some locals in Durango after a trip decades ago and never could find them again. I looked for them back in 2000 when I was doing some cross-country rides on the Harley. And again in 2015 when I went to ride Scotland. Never could find the damned things.
Well I finally ran across them on Amazon and they work just as I remembered.
Super handy for first aid kits, bugout bags, just being outside in the cold, etc.
For those not familiar, the pouch contains a super concentrated sodium acetate solution with small ferrous metal coin inside. When in liquid state, you snap the coin and it sets off a chemical reaction that solidifies the solution, and generating heat in the process. They retain heat about 30 minutes to an hour depending on ambient conditions. Once they cool, they turn into a solid, salt-like consistence. You drop the pouches into hot water for abut 10 minutes to re-liquefy and once they cool they remain in liquid form ready to stow for use again.
Great stocking stuffers for any outdoor types.
