The Alpinestars Tech-Air 5 Plasma Airbag System is engineered to fit comfortably beneath a compatible motorcycle jacket while maintaining an ultra-slim, lightweight profile. Its discreet design creates an almost invisible under-jacket feel without sacrificing comprehensive upper-body protection. The system covers the chest, ribs, back, and shoulders, making it a practical choice for street, adventure, and track riders seeking advanced protection with minimal bulk. This black XS model is identified by Part Number 6504925-10-XS.
The Tech-Air 5 Plasma combines a mono-layer stretch mesh chassis with an integrated Nucleon Plasma back protector. Plasma technology uses a lightweight, flexible, and sustainable impact-absorbing material designed to provide an effective balance of force dispersion, ventilation, adaptability, and comfort. Stretch construction contours to the airbag and supports an adaptive fit, while moisture-wicking treatment and breathable mesh help manage comfort during extended rides. The streamlined chassis is designed to move naturally with the rider and remain discreet beneath a jacket.
A dedicated control algorithm provides three riding modes: Street, Off-Road, and Race. Once the system is switched on, riders can change modes by pressing the system button for two seconds, with a green LED indicating the selected mode. The LED button also allows riders to check system status; a vibration confirms that the system is functioning correctly. A single-canister configuration supports rapid inflation while reducing system complexity, and the gas canister is replaceable by the user for simplified maintenance. The quick-release cover attaches with a hook-and-loop patch and provides convenient access to the inflator when replacement is required. The Alpinestars Tech-Air 5 Plasma delivers advanced airbag protection in a low-profile design built for comfort, breathability, and everyday usability.
