Key Features:

Full Upper Body Coverage
The Tech-Air® 5 PLASMA Airbag System provides comprehensive protection for the chest, ribs, back, and shoulders while maintaining an exceptionally lightweight design for optimal rider comfort.
Ultra-Lightweight Construction
Weighing just 1,530g, the Tech-Air® 5 PLASMA is more than 25% lighter than the Tech-Air® 5, making it the lightest Tech-Air® System to date.
Ultra-Slim, Invisible Profile Design:
With its ultra-slim, minimal material construction, the System fits discretly and is invisible under a jacket, enhancing rider comfort and wearability without restricting movement.
Superior Comfort and Breathability
The System’s full-stretch construction is designed for superior breathability and incorporates a moisture-wicking treatment for maximum rider comfort.
PLASMA Technology for Advanced Protection
Equipped with an integrated Nucleon PLASMA back protector, the PLASMA technology is an eco-friendly, lightweight, and impact-absorbing material designed for superior flexibility, breathability, and ventilation. The protector delivers premium levels of adaptivity for the optimum balance of impact absorption performance, flexibility, and comfort.
Optimized Lightweight Design
The ultra-thin, mono-layer stretch mesh construction is engineered to contour seamlessly with the shape of the airbag, minimizing the System's material bulk—ideal for riders looking for an ultra-lightweight Airbag System with superior breathability.
Faster Inflation and Easy Maintenance
An all-new single-canister design reduces weight, enables faster airbag inflation, and simplifies servicing for quick turnaround.
Quick-Release Cover Design for Rapid Gas Inflator Replacement
The quick-release cover, secured with a Velcro hook-and-loop attachment, allows for easy access to the gas inflator—riders can simply insert a finger into the recess and lift the cover to detach it to access the gas inflator. In countries where gas inflator handling and self-replacement by individuals are permitted by local regulations, riders can quickly replace the gas inflator for continued protection on the ride.
User-Friendly Modular Design
The Tech-Air® 5 PLASMA’s features a fully modular construction, allowing riders to quickly disassemble the System for maintenance and cleaning. Simply unzip the rear stretch mesh panel, release the quick-access cover, detach both the back protector and airbag from the vest, and remove the LED Display and Activation Zip. This user-friendly design enables quick airbag removal for vest cleaning, providing effortless reassembly of the System. Servicing key components, including gas inflator replacement, is also quick and hassle-free, ensuring seamless functionality with minimal effort.
Long-Lasting Battery Life
Provides up to 30 hours of riding time, ensuring reliability for long rides.
Extended Sizing for Optimal Fit
Available in eight sizes from XS to 4XL, offering a tailored fit designed to accommodate a wide range of body shapes.
Riding Modes and LED Display
The Tech-Air® 5 PLASMA features three Riding Modes: STREET, OFF-ROAD, and RACE. After the System has been correctly switched on, the User can easily switch between the three different Riding Modes by pressing the button integrated in the LED Display for two seconds. A solid green LED will appear on the Riding Mode LED, indicating which Riding Mode is currently running. Riders can easily cycle through the Riding Modes until the desired Riding Mode is selected. The System will trigger a short (1-second) vibration when the Riding Mode is changed.
When zipped up, the Tech-Air® 5 Plasma automatically activates via a separate internal magnetic sensor, and the LED Display on the lower chest will not only visually indicate the System’s operational status, but will trigger a short (1 second) haptic vibration alert to notify the rider and confirm when the System is armed. The System generates a long vibration (3 seconds) when turned off or if the System shows a red Status LED.
