Why the ColdAvenger?

"I have raced with the ColdAvenger in -40°F in the North Pole and Antarctica and I would not trust any other product to protect my face and lungs from the freezing temperatures besides the ColdAvenger. It is perfectly lightweight and breathable, but warm and not too hot, and is extremely packable." -- Michael Wardian, Champion Marathoner, Ultra-Marathoner, Winner of The North Pole Marathon in 2014
