Mirage MIPS Helmet The Smith Mirage MIPS Helmet features all the comfort you need for long days taking laps, with adjustable venting and a lightweight in-mold construction. The Multi-directional Impact Protection System (MIPS) helps reduce rotational forces that occur during an oblique impact, and Smith's Aerocore construction combines traditional EPS foam with proprietary Koroyd in order to increase impact resistance and improve airflow. A dial-fit system makes it easy to microadjust the fit—even with a gloved hand—while a cozy liner keeps you warm against the howling wind. The snap in earpieces are audio-compatible, should you desire tunes while you ride, and they can easily be removed when the days are warm.
