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.
