Feeling safe, keeping cool, and looking cool are three top priorities when you are out ripping your favorite trail. With the MTB Trail 3. 0 helmet, achieving each of those priorities is easily accomplished thanks to its included features. On the safety side, 360 Turbine Technology lines the helmet with 360° moving discs that are made from an energy-absorbing material to help protect your head during impact. The MTB Trail 3. 0 is also sure to keep your head temperature down, built with 19 vents to maximize airflow, along with a breathable Dri-Lex liner that is moisture-wicking and washable.
