Inventor: Maiden Ventures, Polartec and North Face Research, Design & Development
Forget the down jacket, the long underwear and the extra-thick scarf. Designed for extreme cold, the North Face MET5 jacket can keep you warm all by itself, thanks to a network of microscopic, waterproof heating elements woven into the fabric. Working a control unit stashed near the chest, you can dial the heat up to 114 degrees F. Small lithium-ion batteries keep the juice flowing for up to five hours.
