The GPX composite off-road helmets are optimized specifically for off-road racing and is extremely ventilated, even at very low speeds. Using a combination of ground-breaking 360? Turbine Technology with Armourgel® cushioning material as impact protection, it helps with brain and rotation safety and reduces the head impact at concussion level by up to 30% and the rotational acceleration to the head and brain by up to 40%. Ten turbines made of 3D molded Armourgel® are set inside the helmet and although they are flexible in their natural state, they harden upon impact, so the faster or harder you fall, the better it works. The helmet also has a 10% smaller shell, which transfers up to 20% less rotational forces to the head and brain. It is compatible with your neck brace and is equipped with a breakaway visor that reduces rotation in a crash. Features Visor with breakaway function for rotational reduction in a crash Low friction cheek pads for emergency removal Hydration ready (with optional hands-free kit) Moisture-wicking, breathable, anti-odor and washable liner (using zinc pyrithion) ECE 2205 Certified and tested Weight in size M: 1.090g +/- 50g Quattro Force Control, composite matrix reduced outer volume shell in three sizes Shell is 10% smaller, transferring up to 20% less rotational forces to the neck, head and brain 360° Turbine Technology Reduces up to 30% of head impact at concussion level Reduces up to 40% of rotational acceleration to head and brain Turbines are made of 3D molded Armourgel® that helps absorb impact forces 3D In-Molded V-Foam Multi-density, V-shaped impact foam molded to the outer shell significantly reduces G-forces transferred to the head and brain Increased absorption, slimmer and a stiffer structure than normal helmet foam Optimal Neck Brace Compatibility Specially designed helmet features and shape to take full advantage of the Leatt® neck brace design Rear hyperextension impact platform with neck brace optimized shape Maximized Ventilation Effective even at very low speeds Optimized for off-road racing Note Please note that as long as nothing else is written in the article description, all helmets that have a visor as standard will be delivered with a clear one, even if it is shown differently.
