Leatt Helmet MTB Gravity 4.0

This helmet is all about offering great protection at a fair price.

Today’s riders face a wide range of variable terrain and conditions. This ASTM DH-certified helmet has you covered no matter what’s ahead. It’s a great option for everything from enduro to bikepark laps to e-bike trail riding.

The full-face-only design offers outstanding ventilation and boasts a clever, modular mouthpiece that’s removable to increase airflow. And the extra-convenient Fidlock® magnetic buckle is easy to operate even when your fingers are cramping with arm pump!

It is important to use a helmet that reduces both rotation and linear impact energy to your head and brain. All Leatt helmets feature 360 ̊ Turbine Technology. This design utilizes a network of small discs constructed of a non-Newtonian, energy-absorbing material. Because these Turbines can move 360 ̊ (omnidirectional), this technology 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.

Add it all up – you won’t find a better option at this price.
