The Venom Snow has the same wind tunnel proven ventilation and plush, Heal-Tec liner as the street version to keep air cycling through the helmet. The included breath box plugs directly into the ports on the chin bar, so the rider gets constant, forced air. The breath box in conjunction with the air diffuser keeps the double-paned shield clear from condensation. The chin curtain provides an added level of warmth and comfort without causing the rider to feel stuffy. There’s even a version with an electric shield or an optional electric shield accessory.
