The new Quantum is protection with maximum horsepower. Using Aerocore™ construction featuring Koroyd® and Smith’s innovative Exoskeleton design to provide increased protection in side-impact zones, this is the helmet for athletes pushing the limits on the mountain. The new Wayfinder Strap System featuring Fidlock® is functional simplicity, making it easy to use one hand for on and off buckle use. For the most custom fit, the Quantum offers the Boa® FS360 fit system with a 360˚ halo design. Combine all this with the Smith-pioneered AirEvac technology for superior goggle integration. The Quantum delivers maximum protection and functionality for use in the most critical situations.
