Blowing into your hands to warm them up isn't exactly new or tech-savvy, but Gorgonz has managed to give that old method of self-heating a 21st-century upgrade.

Their new line of gloves has a small mouthpiece for blowing in, and your hot breath gets trapped inside and circulates to the fingers. It's a low-tech yet innovative way of staving off frostbite after you stupidly get lost in the Andes while trying to impress your buddies.
