About this item

• FIT: A BOA 360 fit system includes an adjustable dial that delivers a more secure fit and maximizes safety. Overall improvements to the shell shape ensure ARO5 Race sits lower on the head for better balance, while fitting more naturally to the contours of your head.
• LIGHTWEIGHT: ARO5 Race is lighter than its predecessor, the ARO5, achieved through a newly designed shell and other internal modifications.
• PROTECTION: The Mips Air safety system is a helmet-integrated, low-friction layer designed to decrease rotational motion to the head, helping to reduce the harmful forces that might otherwise impact the riders head.
• VENTILATION: ARO5 Race features newly designed front and top ventilation ports to significantly increase airflow and breathability. There are 19 vents in total across the top, side, and rear sections.
