Lazer Nutz helmet with the new Kineticore technology from Lazer. The Nutz helmet is made for bigger children and fits head sizes of 50-56 cm. It goes all the way down the neck and at the temple for extra security in those areas. There is insect netting in the front vents. The buckle is on the side to make it easier to fasten the helmet on the child's head and at the same time avoid pinching the skin under the chin. The back of the helmet is made straight and relatively flat so it is compatible with child seats. 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.
