The Troy Lee Designs D2 Helmet sets the benchmark in impact protection, ventilation, and bold style. Its Aerospace composite shell offers high levels of impact protection, as evidenced by passing rigorous CPSC 1023, CEEN 1078, ASTM F2032 00, and F1952 00 safety standards. The removable, washable comfort liner and cheek pads keep the helmet fresh after long days of lift serviced downhills and shuttle runs. High flow ventilation actively disperses built up heat and perspiration, thanks to its seven intake and four exhaust ports. The adjustable Orbit visor keeps the sun off your face, while protecting you from passing brush and oncoming elements. Moreover, you'll appreciate the large eye port, which is compatible with a wide range of goggles.
