Smith Optics produced the all-new Smith Forefront helmet for riders that need all-mountain protection with road-race weight. Where this helmet truly stands out is in its construction: a recyclable polymer product called Koroyd combines with EPS foam to create a system of materials known as Aerocore. This honeycomb-like structure takes the place of traditional EPS foam in much of the helmet and absorbs 30% more energy in an impact than traditional foam while dropping weight at the same time. The Forefront has all the functions you demand in an all-mountain helmet including integrated camera/light mounting area, adjustable and removable visor, and a helmet goggle retention strap. The large vents keep air flow to a maximum so you can concentrate on the trail. 295 grams. SM (51-55cm), MD (55-59cm), LG (59-63cm).
