Oakley ARO3 Endurance MIPS helmet

The Oakley ARO3 Endurance Road Bike Helmet is a high-performance cycling helmet designed for endurance road cycling and racing applications. This model offers advanced aerodynamics with a streamlined shape that reduces air resistance while maintaining optimal ventilation through strategically placed air intake and exhaust vents. Constructed from a lightweight yet durable polycarbonate shell with an EPS foam liner, it ensures reliable impact protection according to the European safety standard CE EN1078. The helmet integrates Oakley's patented MIPS system (Multi-directional Impact Protection System), which provides a low-friction layer to reduce rotational forces during oblique impacts. Ventilation is optimized with 18 large air vents that promote a constant airflow to keep the rider cool during long rides. The adjustment system features a precise dial at the back of the head for a secure, customized fit, complemented by padded straps with a magnetic Fidlock closure for easy one-handed operation. The interior padding is made from moisture-wicking, antimicrobial materials that enhance comfort and hygiene. The helmet is compatible with most cycling sunglasses and sports glasses, with the temple areas designed to accommodate eyewear frames without interference. Available in several color options, it weighs approximately 270 grams in size Medium (57-58 cm head circumference). The ARO3 embodies Oakley's commitment to combining aerodynamic efficiency with practical ventilation and safety features for ambitious cyclists.
