The HJC ADWATT 1.5 White Size M Bicycle Helmet is engineered for superior performance, especially for long rides and triathlons. It strikes an ideal balance between aerodynamic efficiency and rider comfort.

Weighing approximately 260 grams without the visor and 320 grams with it, this helmet is lightweight yet durable. The size M accommodates head circumferences of 55 to 59 cm. Its aerodynamic profile has undergone extensive wind tunnel testing, significantly reducing drag forces to enhance road performance while ensuring optimal cooling.

A highlight of the helmet is its Ventury Dynamics technology, which utilizes Bernoulli's principle to maximize airflow. This innovative system enables air to move quickly over the helmet’s surface, generating a pressure difference that pulls cool air in from the front and expels warm air through the rear vents. Riders can enjoy a continuous stream of cooling air throughout their rides.

Additionally, the helmet comes with a premium case for safe travel and includes a visor to enhance visibility, all while preserving its aerodynamic characteristics.

Key Specifications:

• Weight (helmet only): 260g (±10g)
• Weight (with visor): 320g (±10g)
• Size (M) Head Circumference: 55–59 cm
• Ventilation: 2 vents with Ventury Dynamics airflow
