RST D3O Essential Motorcycle Airbag Vest - 4XL / 5XL

The RST D3O Essential Motorcycle Airbag Vest provides active upper body protection by deploying an electronically controlled airbag during specific crash scenarios. It uses the RST Essential Airbag system powered by in&motion s Intelligent Algorithm, supported by internal motion sensors and a rechargeable control unit, alongside a D3O Level 2 back protector and stretch mesh chassis to manage impact forces.Discover the key features of this vest:in&motion Intelligent Airbag Control Unit (ICU): The integrated ICU contains accelerometers and gyroscopes that record thousands of data points per second to analyse your speed, lean angle and acceleration in real time, using a continuously updated crash detection algorithm developed from extensive riding data to distinguish between normal riding dynamics and accident scenarios, which enables the system to trigger deployment only when required and provide targeted upper body protection during a fall, high-side or collision event.Rapid Inflation Airbag Bladder: The internal airbag bladder is engineered to inflate in milliseconds once a crash is confirmed by the ICU, directing compressed gas through calibrated channels to create protective cushioning around key areas of your torso including the chest, abdomen and back, which helps to absorb and distribute impact energy across a broader surface area and reduce the force transmitted to critical structures.Rechargeable Lithium-Ion Battery System: The self-contained lithium-ion battery powers the ICU and is rechargeable via a dedicated charging port, delivering multiple hours of active riding time per charge so you can rely on consistent monitoring throughout your journey and maintain full system readiness with routine charging.D3O Level 2 Back Protector: Fitted with a CE-certified D3O Level 2 back protector, this insert uses impact-reactive material that remains flexible during normal movement and stiffens under sudden force, dispersing energy across the surface to limit peak transmission to your spine and supporting the airbag system with passive protection.Quick Dry Stretch Mesh and Lycra Chassis: The quick dry stretch mesh and Lycra construction holds the airbag assembly and control unit close to your body, promoting accurate sensor readings and correct deployment geometry while managing moisture and airflow for consistent comfort under your jacket.Silicone Hem Retention Grip: An integrated silicone hem grip stabilises the vest at the waist, helping to maintain correct positioning of the airbag and sensors so the protection system deploys from the intended location during an incident.You benefit from a protection system that continuously analyses your riding inputs and responds automatically when a crash is detected. The electronic monitoring, rapid inflation sequence and integrated armour work together to manage impact energy across your upper body during real-world road use. As part of your riding setup, this vest is a considered addition that strengthens your overall protection strategy with intelligent, data-driven technology.2 Year Warranty
