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.
