The folks over at Gear Junkie got a chance to visit the product development lab at North Face's new headquarters in Alameda, California. One of the many new innovations they were shown was this wonderful runner's jacket that uses a clever ventilation system to cool you down.
Tugging on a pair of elastics on the updated Stormy Trail runner's jacket seals off the coat at the waist. So as the wearer runs, air entering the jacket through a series of vents can't escape out the bottom. Instead, it flows up the runner's back and escapes out another vent closer to the top of the jacket, taking heat with it and cooling the wearer in the process. It's as close as a jacket can get to air conditioning, and will be available next July for about $US165. [Gear Junkie]
