From the manufacturer

Buckle up and hit the trail. The Smith Pilot mountain bike helmet is the total package for trail riding. It combines a durable, lightweight build with elevated safety tech and on-the-fly adjustability. A Mips® liner system helps reduce angle impact forces in a crash, and fixed vents provide the airflow you need to stay comfortable through climbs and descents. An easy-to-use dial lets you fine-tune the fit, and side channels let you secure your shades between laps.
