Smith Forefront Mountain Bicycle Helmet. While you may best know Smith Optics for stellar performance eyewear, they also know a thing or two about world class helmets. The Smith Forefront is a full coverage Bicycle Helmet ideal for all mountain riding or racing that sports a distinct, eye catching design. 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. Finding a precision fit is a breeze courtesy of the VaporFit retention system while the X Static liner plus ultra light webbing provide incredible comfort. Smith really dotted every i and crossed every t as the Forefront also sports an integrated camera and light mount plus includes a goggle retention strap. So when it comes to extreme venting, protection, and safety in a lightweight design, the Smith Forefront is truly at the vanguard every time.
