We choose the G1 MIPS Helmet for our road rides because the ventilation and aerodynamic profile make it an efficient option for logging miles. 22 total vents keep us cool and Lazer's Rollsys retention system provides a 360degree fit and comfort in a lightweight design that adjusts from the top of the helmet and away from our hair. For added peace of mind, a MIPS layer in the G1 redirects rotational forces in the event of an impact.
