Lazer Jackal mtb helmet with the new Kineticore technology from Lazer. The Jackal helmet has internal ventilation channels and a large adjustable visor. There is room for goggles under the visor if it is moved up. The buckle is magnetic and the helmet's circumference is adjusted with Lazer's Advanced Turnfit system that sits like a turnbuckle around the neck. Kineticore implements crumble zones as you know them from cars in your helmet. The idea here is that these zones absorb some of the force of an impact and cushion it in the helmet. It works in all directions, both direct impact and rotating crash. With Kineticore, Lazer can save plastic and EPS in their helmets, resulting in a smaller climate footprint from their helmets. In addition, it provides better ventilation.
