Leatt MTB Gravity 4.0 Helmet

Renowned for its ventilation and comfort, the MTB Gravity 4.0 helmet is fitted with 360 degree Turbine technology, offering great protection at a fair price. This fully ASTM DH certified helmet is the go-to helmet for enduro and bikepark riders. Uphill, downhill, upside down, E-bike or trail - you name it, the Gravity 4.0 has you covered. The full-face design with removable mouthpiece offers outstanding ventilation and its convenient Fidlock buckle makes life just peachy! Leatt helmets feature 360 degree Turbine Technology. The helmet is lined with turbines which are 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. So, the next time you crash, see to it that you are protected by the best!
