Engineered for riders who demand top-tier protection, comfort, and performance, the Troy Lee Designs A3 Helmet sets a new benchmark for premium trail and all-mountain riding. Combining advanced safety technologies with exceptional ventilation and fit customization, the A3 delivers confidence on everything from technical climbs to aggressive descents.
At the core of the A3 is a dual-density EPS and EPP impact liner paired with Mips® Brain Protection System, helping reduce rotational forces during angled impacts. A reinforced aerospace-grade filament shell enhances structural integrity while keeping weight low. The helmet’s extensive ventilation system features large intake and exhaust ports connected by deep internal channels to maximize airflow and cooling on long rides.
Comfort is equally impressive thanks to the Precision Fit system, which offers three-way adjustability for a secure, personalized fit. Ionic® comfort padding provides moisture-wicking, antimicrobial performance, while a sweat-management system helps keep perspiration away from your eyes during intense efforts. Additional rider-focused details include an adjustable visor with goggle storage capability and integrated eyewear docks for secure sunglass storage between climbs and descents.
Whether you’re tackling backcountry epics, technical singletrack, or bike park laps, the Troy Lee Designs A3 Helmet delivers premium protection and all-day comfort for every ride.
