the NILS Extreme MTV65 is a cycling helmet that ensures a safe ride whether your child is riding a bike or, for example, on a scooter, skates or skateboard. the MTV65 model is manufactured using the Out-mold technology, where the PVC top cover is glued to a polystyrene support. In the event of an impact, the enrgy is distributed over the entire surface of the helmet and further transmitted through the foam pads. the helmet is available in two sizes and has a system for easy adjustment of the head circumference by turning a wheel in the back of the helmet. A plastic buckle on the adjustable strap makes the MTV65 easy to put on and take off.
