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 1,530 g, the Tech-Air® 5 PLASMA is over 25% lighter than the Tech-Air® 5, making it the lightest Tech-Air® system to date.
Ultra-thin, stealth-like design:
Thanks to its ultra-thin, minimal structure, the system fits discreetly and invisibly under the jacket, improving the rider's comfort and fit without restricting movement. Superior comfort and breathability
The system's fully stretchable construction is engineered for superior breathability and incorporates a moisture-wicking treatment for maximum rider comfort.
PLASMA technology for advanced protection
Featuring an integrated Nucleon PLASMA back protector, PLASMA technology is an environmentally friendly, lightweight, and highly shock-absorbent material designed to offer superior flexibility, breathability, and ventilation. The back protector offers excellent levels of adaptability for an optimal balance of shock-absorbing performance, flexibility, and comfort.

Optimized lightweight design
The ultra-thin, single-layer stretch mesh construction is designed to perfectly match the shape of the airbag, minimizing the system's material bulk: ideal for riders seeking an ultra-lightweight airbag system with superior breathability.
Faster Inflation and Easy Maintenance
The all-new single-cylinder design reduces weight, allows for faster airbag inflation, and simplifies maintenance for quick replacement.
Quick-Release Lid for Quick Inflator Replacement
The quick-release lid, secured with a Velcro strap, allows for easy access to the inflator: riders can simply insert a finger into the recess and lift the lid to remove it and access the inflator. In countries where individual handling and replacement of the inflator is permitted by local regulations, riders can quickly replace the inflator for continued protection while traveling.

Intuitive Modular Design
The Tech-Air® 5 PLASMA features a fully modular design, allowing riders to quickly disassemble the system for maintenance and cleaning. Simply unzip the stretch mesh back panel, unclip the quick-access cover, detach both the back protector and airbag from the vest, and remove the LED display and activation zipper. This intuitive design allows for quick removal of the airbag for cleaning the vest, allowing for effortless reassembly of the system. Maintenance of key components, including replacing the inflator, is also quick and hassle-free, ensuring flawless functionality with minimal effort.

Long-lasting battery
Provides up to 30 hours of use, ensuring reliability even on the longest rides.

Extended sizes for an optimal fit
