The Anon Highwire is a stylish and value driven helmet. Anon's Endura-Shell Construction feels light on your head without any compromise to protection. The Auto-Adjust Fit System gives you a perfect fit after just a simple adjustment. Passive Ventilation keeps a steady stream of cool air coming in through the front of the helmet, while pushing warm air out the back to prevent you from overheating on the mountain. A Goggle Ventilation Channel keeps air circulating across the top foam of your goggle to help fight foggy lenses. Anon has added Expedition Fleece on the Liner and Ear Pads to provide you with extra warmth on those frosty January days when the snow is good, but it's cold and you have to keep riding.
