The Carve 2 helmet is lightweight, highly ventilated, and offers super protection for mountain bikers. Super MSB technology is a ring-shpaed protection at the base of the helmet that reinforces the perimeter for enhanced protection. Highly inspired by the Exo-Nerv technology seen in earlier Louis Garneau helmets, the U-Bar technology is made with U-shaped plastic ribs that are folded 6 times. These ribs act like a complex ekoskeleton that reinforces the helmet's structure. The patented Spiderlock® Pro II is a helmet stabilizing system with a light ventilated polymer neck support. It can be easily tightened on the head using only one hand and its inclination can be adjusted to several positions.
