Created to provide all-mountain protection at a road-race weight, the Aerocore construction of the Smith Forefront MIPS All-Mountain Helmet gives riders and racers 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 a Multi-Directional Impact Protection System to reduce the rotational forces to the brain in the case of angular impacts. The 360 VaporFit retention system and minimal X-Static padding effectively suspends the helmet off your head, allowing each and every Koroyd tube to constantly evacuate hot air. This helmet fully integrates with your sunglasses, goggles, light or POV camera, plus there's a retention strap to hold your goggles in position at the back of the helmet. Want more? The Forefront MIPS tips the scales at a mere 339g, as if you weren't already impressed. When it comes to extreme venting, maximum protection and safety in a lightweight design, the Smith Forefront MIPS All-Mountain Helmet comes out ahead, every time.
