ColdAvenger

If you're planning on training up for Winter X Games 15, do yourself a favor and protect your face and respiratory tract with the ColdAvenger ($50-$60). This advanced cold weather mask employs a patent-pending ventilation design to mix inhaled cold air with exhaled warm air, keeping the temperature inside the mask up to 40º to 60ºF warmer than the outdoors, while still allowing for easy breathing during exertion and keeping your face dry. Sure, you'll look a little like a Star Wars extra while wearing it, but that's a small price to pay for warmth.
