Sanyo has also indulged in a little bit of technological fashion with their new range of Eneloop warmers that includes a neck warmer. It will be powered by a rechargeable battery for added portability, the Eneloop neck warmer will target those who involve themselves heavily in various winter sports including skiing, while folks who still go around on a bicycle or motorcycle when it is freezing outside might appreciate this. The wamer comes with a heating section that wraps itself snugly around the neck, and it would be nice to see this come with a solar panel to keep things even greener. Available as a one-size-fits-all solution, this unisex device comes with a size-adjustable belt. You can remove the thermal section and power supply whenever it is due for a wash.
