Featuring 360 ̊ Turbine Technology, the helmet is lined with turbines which are 360 ̊moving discs constructed from an energy-absorbing shape and material, this tech has two exclusive advantages, namely the reduction of rotational acceleration to the head and brain and the absorption of energy upon impact at concussion level.

Air vents are not covered, which make this helmet well ventilated. Ideal for warmer downhill or bikeparks days.
