Alpinestar Tech-Air® Off-Road System Size – L

Developed in Dakar since 2017, the Tech-Air® Off-Road System is Alpinestars’ most advanced MX airbag system for off-road rally and enduro riding. FIM-homologated with CE Level 1 airbag coverage for the chest, back, shoulders, collarbones, and neck, it adds dual-charge inflators and ENDURO, RALLY, and STREET modes. Breathable stretch-mesh comfort, roost resistance, and an included 1.5–3L hydration bladder holder support long stages.

• Dual-charge deployment: one inflator activates per event, preserving a backup for continued protection on long rides.
  
• User-replaceable gas inflators: quick turnaround between rides (where local laws permit) without sending the unit in.
• Self-contained sensor suite: integrated accelerometers and gyroscopes in the ECU for precise detection with no external sensors to install.
• Long-life battery and fast charging: up to 30 hours of runtime; USB-C on the LED display delivers a full charge in ~4 hours and about 8 hours from a 1-hour top-up.
• Auto activation zipper: the Tech-Air® Off-Road System powers on when zipped and safely deactivates when unzipped for hassle-free use.
• Shipping Mode switch: disconnects the battery for travel or long-term storage, protecting the system and conserving power.
