I’ve got a DAir smart jacket. I was using the jacket with updated firmware version. According to their user manual, the airbag can’t trigger if you travel at less than 10Km/h AND you are not riding the bike. In my case, I was neither, moving at 10 km/h nor riding the bike. Actually, I was stepping out my bike, just storing the helmet at the vault when suddenly the airbag popped. The airbag triggered in an specific situation the manual says it must not do it. As I was basically “doing nothing” when the airbag was triggered, this worried me a lot, because it can also trigger when you are riding and cause an accident. When the airbag pops, it’s a really abrupt move, so it can easily make you fall from the bike. I contacted Dainese Spain and I was expecting, not only to repair my DAir Smart Jacket for free (it was in guarantee and obviously the product did not function correctly), but also to download the data from the jacket to understand what went wrong. They told me that it was my responsibility, that I needed to pay 250€ (half of the cost of the product) to reequip the airbag, and they where not interested at all in getting data or understanding what when wrong to patch their product. I’ve got two DAir jackets, I decided to sell the one which is still working and I will not repair the faulty one because I really can’t trust it. I will look for another solution. Alpinestars and Ixon has also good alternatives.
