Smith Forefront Helmet / ICEdot Crash Sensor
Made with a unique honeycomb material that provides impact resistance while allowing airflow and ventilation, the Forefront helmet from Smith will keep your noggin safe and cool while tearing down the single-track.
And while you're at it, attach an ICEdot crash sensor for extra security. Upon sensing an impact, the sensor, combined with the ICEdot smartphone app, notifies your emergency contacts and sends out your GPS coordinates unless stopped by you.
