Great for snow blowing. Or when the snow is blower. The Airblaster Air Flap Cap utilizes our 10K outerwear fabric as an outer shell, paired with ultra kush brushed fleece for the lining. As a bonus, this cap functions as a weather indicator: Ear flaps up, it could be cool out. Ear flaps down, it might be cold. Either way, you're cozy and protected from mother nature's icy breath, 'case she tries to whisper in your ear again.
