Riding is for everyone, so we created the Camber to provide a dialed fit for rippers of all sizes, from kids on up. The Camber comes equipped with all the comfort, style, and ventilation to make every ride a joyride. For helmets sold in the U.S. and Canada: Complies with U.S. CPSC Safety Standard for Bicycle Helmets for Persons Age 5 and Older. Camber earned the highest 5-Star Virginia Tech® Helmet Rating™ from internationally renowned Virginia Polytechnic Institute and State University. The MIPS system is a low-friction layer that allows a sliding motion of 10 to 15mm in all directions. Studies indicate that this reduces some of the rotational forces transmitted to the brain during angled impacts. With x-small to x-large options spread across five unique shell sizes, the Camber eliminates excess bulk to deliver a comfortable and streamlined fit to a full range of riders. Easily-adjustable, one-size Headset SX fit system with adjustable Tri-Fix web splitters delivers an easy and accurate fit. 4th Dimension Cooling System optimizes ventilation. In-molded shell improves strength and reduces weight. Average weight: 370 grams (medium).
