The Dainese Airbag system D-Air® protects the back and vital parts of the motorcyclist thanks to its Shield, the special patented sack with microfilaments that ensures the maximum absorption capacity of the impacts, without the need for rigid protectors. What makes Smart Jacket unique is the Shield, the patented sack by Dainese which thanks to its exclusive structure with microfilaments guarantees a homogeneous and controlled inflation, offering the same level of protection in every single centimeter of the jacket area. The brain of the Smart Jacket is the Dainese system control unit D-Air®, which without the need for cables and connections with the bike or scooter independently detects a dangerous situation and immediately activates the Shield to protect the motorcyclist. Always at the ri.
