Developed for road, dirt, and track riding, the Tech-Air® 5 Plasma System is an under-jacket motorcycle airbag. Delivering full chest, ribs, back and shoulder coverage with CE EN 1621-4 Level 1 airbag certification, it weighs 1,530 g and integrates a PLASMA back protector, STREET/OFF-ROAD/RACE modes, and a single-canister, user-replaceable inflator. Its ultra-slim, breathable chassis disappears under a jacket, while up to 30 hours of battery life keeps protection ready.
  • Upper-body impact zone coverage: extends protection across critical torso areas to help reduce injury risk during a crash.
  • Ultra-lightweight chassis (approx. 1,530 g): reduces bulk and rider fatigue; more than 25% lighter than the Tech-Air® 5 for enhanced comfort.
  • Ultra-slim under-jacket profile: delivers an “invisible” fit that moves naturally and doesn’t restrict movement.
  • Breathable, moisture-managed fit: stretch materials and wicking treatment help keep you cool and comfortable on every ride.
  • PLASMA back‑protector technology: balances impact absorption with flexibility and ventilation for everyday comfort.
  • Mono-layer stretch mesh integration: contours to the airbag to minimize bulk and maximize airflow.
  • Single‑canister inflator: reduces weight and enables faster inflation for responsive protection.
  • Quick‑release service cover: allows user‑replaceable gas inflator (where legally permitted) for rapid turnaround after a deployment.
  • Modular system design: simplifies use and servicing for ongoing protection.
  • Extended battery life: provides up to 30 hours of ride time per charge.
  • Expanded size range: eight sizes (XS–4XL) for a tailored, inclusive fit.
  • Three Riding Modes with LED control: STREET, OFF‑ROAD, and RACE; switch modes by pressing the LED Display button for 2 seconds with a vibration confirmation.
  • LED/haptic status alerts and auto activation: clear visual/vibration feedback and automatic arming when zipped via the internal magnetic sensor on the Tech-Air® 5 PLASMA Airbag System.
  • Active Protection: The airbag provides comprehensive full upper-body coverage, safeguarding the chest, ribs, back, and shoulders.
  • Integrated Back Protector: Integrated Nucleon PLASMA back protector positioned to reinforce full-back impact protection and complement the airbag’s coverage.
  • Stealth Back Protector Design: Back protector contours to the electronics case to maintain continuous protective coverage and secure integration within the system.
  • CE-Certified Protection:
  • The Tech-Air® 5 PLASMA Airbag System and all included protective parts are Category II certified PPE (Personal Protective Equipment) under European Regulation (UE) 2016/425 and in compliance under corresponding UK legislation.
  • The passive back protector is CE certified according to EN 1621-2:2014 Level 1 (Full Back).
  • The inflatable protector is CE certified according to EN 1621-4:2013 Level 1 (Full Back).
  • The system is CE certified as a protective garment for motorcycle riders according to EN 17092-6:2020 as a Class C undergarment.
  • Airbag Deployments: The airbag is certified for up to six deployments before requiring replacement.
  • Ultra-thin mono-layer stretch mesh chassis at the collar, underarms, and front panels for low material mass and high airflow.
  • Ergonomic sleeve pattern with a deeper underarm cut to reduce material stacking and seam bulk.
  • Extended rear hem and contoured, low-cut neckline to increase coverage while minimizing edge-to-skin contact.
  • Chassis engineered to align with Alpinestars jacket ventilation channels, ensuring direct vent path through mesh zones.
  • Anatomically contoured airbag bladder with strategically positioned cutaways to expand the protection envelope across the back, chest, ribs, and shoulders while controlling overall volume.
  • Integrated Nucleon PLASMA back protector constructed from a viscoelastic compound co-injected with elastomer compounds for a slim, flexible, ventilated structure.
  • Minimal use of plastic components to achieve a low weight-to-performance ratio and maintain free airflow within the chassis.
  • System weight: 1,530 g.
