Giro Omen Helmet The Omen is a revolutionary helmet designed for riders seeking all-mountain versatility, custom-tunable fit and adjustable ventilation for comfort and performance in a wide range of riding conditions. It is also the first helmet to combine internally channeled active ventilation and built-in resistance to penetration; a fully integrated adjustable fit and positioning system; and optional wireless audio'telephony. All of this in a design thats light enough for everything from core freestyle riding to serious backcountry explorations. The Omen really pushes helmets to a whole new level, said Eric Richter of Giro. Its the first helmet to advance everything that matters to riders - style, fit, ventilation, construction and even audio and communications. Plus, its light and tough enough to go with you from AK steeps and chutes to parks to backcountry powder stashes. The Omens compact shape is wrapped with an innovative blend of front and rear high-impact ABS shells for proven toughness, combined with the durability and lighter weight of In-mold Hardbody construction. Incredible cooling power comes from 14 Wind Tunnel vents with deep internal channels that pull air into and through the helmet while exhausting heat and stale air out, and controlled via dual Thermostat sliders that allow riders to open and close every vent instantly as conditions demand. And for the ultimate in comfort and performance, an intergrated In Form adjustable fit system (engineered specifically for use with snow sports helmets) makes it easy to dial-in customized helmet fit and positioning with goggles.
