Motorcycles are inherently dangerous and riders are only allowed so much protection from the gear that we choose to place on our bodies. Dainese has always been an innovator when it comes to motorcycle safety. They were the first to incorporate back protectors into the leather pajamas that early motorcycle racers wore in the late 70's, and more recently they were the first to dream up the incorporation of airbags into jackets and race suits in 1995 and then implement them for testing in 2000.
As is the way when you have a good idea, others latch on like a bunch of lampreys and suck the life right out of it. There is a bit of a legal battle over the patents of the use of airbags in motorcycle gear. Alpinestars and Dainese are currently engaged in a he-said-she-said over the patents. Dainese holds several patents and had issued a cease and desist to certain German retailers of Alpinestars Tech-Air systems. AStars tried to get ahead of the news publicly by issuing a statement to the press essentially stating that the cease and disist had been issued, but not a legal action. Thus leaving readers to infer that they had done nothing legally wrong.
