The 3-Qtr Air is a lightweight, well-ventilated open-face mountain bike helmet for riders who want extra coverage without committing to a full face. Inspired by the Full Air platform, its 3/4 design extends protection around the upper neck and jawline while keeping the freedom and breathability of a half-shell, making it well suited to enduro, trail riding and bike park sessions.
MIPS helps reduce rotational forces during impacts, while the Dual Flow ventilation system keeps airflow high on climbs and descents alike. A Fidlock magnetic buckle fastens securely with one hand, even in gloves, and the removable, washable antimicrobial liner keeps the helmet fresh ride after ride. An integrated quick-release action camera mount under the visor makes it easy to capture POV footage.
