Smith Vantage Helmet is one of the best ski helmets available, with a revolutionary venting system. The most ventilated Hybrid Shell helmet ever created, the Vantage features a Dual Regulator that separates the ventilation into zones, all in a low volume, lightweight package. You modify the amount of airflow and heat on the helmet, even with a gloved hand. Open all 21 vents to exhaust maximum heat in the shortest time, close the front vents when you're riding hard in cold weather, and close them all on the lift. Hybrid SL, or 'super light,' shell construction minimizes weight while maintaining the durability of Smith's classic Hybrid Shell, which fuses its flyweight In-Mold and injection-molded Bombshell ABS constructions. X-Static performance lining is a silver-coated textile fiber that provides natural odor control, anti-static and thermo-dynamic properties. Snapfit SL ear pads are ergonomically designed to be form fitting and comfortable, and are easily removable for washing. Removable ultralight goggle lock. AirEvac 2 Ventilation integrates Smith snow goggle and Smith ski helmet ventilation systems to prevent goggle fog by utilizing helmet shell vents as well as internal channels in the EPS liner to increase airflow and evacuate warm, moist air over your head and out the back of the helmet. Adjustable Helmet Fit System (HFS) ensures a perfect fit. A soft, flexible plate and liner system contact the back of the head when the HFS is tightened. The self-centering system utilizes an intuitive pinch and pull design with 3 attachment points for easy operation. Compatible with Skullycandy, Bluetooth and Twin-Tip Link Phone-Audio systems.
