Heat generating fabric

[Maxwell_Allen]

Has anyone seen or tried this new Mizuno "Breath Thermo" stuff?
Apparently it releases heat when it gets wet!

They sent me a small baggie of the fiber, it seems to work, but i haven't a clue how.

Maybe I'm missing something - if you are sweating enough to activate this shirts heat-producing properties, why would you want to generate more heat? I can see some applications - like for toasty socks and mittens in wet weather.

They are coming out with products that have paraffin type molecules embedded in the fabric that "melt" when they absorb heat and moisture, and as they dry they reform back into a solid state releasing the absorbed heat.
