Celebrating 40 Years of Creative Horsepower - Troy Lee Designs, Born in Corona, California

The A3 mountain bike helmet, a product of Troy Lee Designs, sets a new standard in premium mountain bike helmets. Crafted with luxurious comfort, patent-pending innovations in coverage and ventilation, this helmet will keep you cool on the longest climbs and provide comfort and coverage on the sketchiest of descents. Earning the highest possible score (5-STAR) from the VT helmet lab, you can feel confident in its performance in all conditions.

Featuring a 3-piece shell layup, the helmet's technical refinement and aesthetic appeal are enhanced, allowing for more design options and the integration of different EPP/EPS materials for additional coverage. The carefully designed Eva Foam, installed via adhesive backing behind the comfort liner along the front brow, effectively directs sweat away from the eyes and optics.

The patent-pending magnetic adjust visor system, known as the Magnajust system, enables you to easily stow your goggles on the upswing, and the visor will automatically click back into position when you put your goggles back on. The MIPS B-Series solution allows the TLD fit system to attach directly to the MIPS LFL, creating an optimal 360-degree fit for a perfect helmet fit.

Featuring composite smart-shear screws with anodized washers, the A3 helmet also includes a patent-pending impact liner that combines EPP low-density coverage foam for low-speed coverage and a more firm EPS layer for high-speed coverage. The Fidlock magnetic buckle provides easy on and off, complemented by a 3D molded TLD badge on the surface.

The A3 helmet comes with a drawstring helmet sock, an additional spare EVA foam installed via adhesive backing, a set of Velcro strips applied around the inner shell, and a 15-sticker set sheet, ensuring a customizable and versatile experience.

Continuing the legacy of Troy Lee, who started as a motocross racing teenager painting helmets in his parents' garage, Troy Lee Designs has grown to become the premier custom helmet paint shop in the world, supplying motocross and mountain bike gear to the world's fastest racers.
