I remember throwing those little hand warming packets in my mittens while I froze my butt off at Giants games as a kid, so this Bodywarmer gear looks like a grand idea. Made from fabric that self-heats using hidden heating wire woven right in, these vests, jackets and gloves are also water resistant. Between 3 and 6 AAA batteries are needed to power the material, depending on what you're trying to heat up.
