Created to provide all-mountain protection at a road-race weight, the Aerocore construction of the Smith Forefront All-Mountain Helmet gives riders ventilated protection, as never before seen in a bicycle helmet. Smith took a patented tubular core structure of Koroyd material and combined it with EPS to produce a system of materials called Aerocore, which are designed to surpass current standards at low and high speeds. What you get is up to a 30% improvement over standard EPS impact properties, awesome ventilation and protection, plus reduced weight and volume. It also features Smith's new VaporFit retention system for a perfect fit, integrated camera and light mounting area for convenience and goggle retention strap, so you don't have to worry about slipping eyewear. Want more? The Forefront tips the scales at a mere 285g, as if you weren't already impressed. When it comes to extreme venting, protection and safety in a lightweight design, the Smith Forefront All-Mountain Helmet comes out ahead, every time.
