I just noticed these while checking out their anti-bug products. As someone who has trouble keeping their feet warm during an all-day sit, these look intere$ting. Being able to switch the source of heat on/off, and modulate the intensity would be useful.
During my deer hunting travels, I often cross through some swampy sections. So I wear those tall, rubber boots. The boots seem fine for a few hours once up in the stand, but really cold temps can sap the heat out of them quickly. I've tried those heat pack envelopes. They pack up and become useless quickly.
