    I dont know whom said there hit air didn't inflate but unless you move the peace that stop in inflating when you get it , it will not go off. Is a collar of some type that is by the co2 cartage . It is mean to stop it inflating by chance when transporting it .

    You did not make a bad decision at that price,or for the vest itself!

    It was my tether-based airbag that failed to inflate in a crash. There wasn’t an issue with the piece to stop it inflating; the airbag was set up correctly, which I checked with the manufacturer after the crash.

    I’ve now switched to an electronic airbag: Alpinestars Tech-Air. The Tech-Air is a cleverer system. It deploys more rapidly and in a wider range of circumstances than a tether-based airbag. Also, I find it more convenient than a tether-based system because there’s no messing about with a tether. The Tech Air’s only downside is the price. Though I feel it’s worth the investment for MotoGP-tested technology whose firmware I can keep up to date via Alpinstars online.

    I disagree. I think it’s cool that consumers can ask questions and interact with manufacturers of various Moto gear. We can give feedback and suggestions on improvements and vendors can help support the products here as well. Most forums people simply SLAM a product and people pile on. Here, the manufacture can make corrections and make adjustments as needed. YMMV but I like it!

    It looks like the Alpinestars offers significantly more airbag coverage/protection.

    I like the shoulder coverage.

    Me too. I've read somewhere that many spinal injuries are caused by impact to the shoulder, causing the spine to twist. If this is true, then the Tech-Air's shoulder protection matters for more than just the shoulder itself. I'd be interested in any medical opinions on this ...

    How do you ventilate a large air bag that has to hold air, and resist compression forces in a crash? This may be one of the things we will have to get used to.
    At least this design turns the once solid back pad, into something that is majorly honeycombed. That's an advancement I've already seen in this first generation of vests.

    I like that, and the extensive side rib protection. Something most of the other under jacket vests are missing.

    If you have a jacket with a lot of ventilation in the arms, such as Alpinestars Revenant, then you can have significant ventilation. It mightn't be enough for summer weather in Florida, but good ventilation in the arms will be enough for many places (e.g. most summers in the UK).

    Anyone know whether the A* Tech Air 5 is recommending/requring removal of your 'conventional' shoulder armor? Also any idea about the space required in the sleeves/shoulders? I bought a really nice expensive gore-tex suit which fits me super well with CE2 armor so I'm wondering if I'll need to buy a larger jacket as well...

    Blaise, I would hazard a guess that you should keep the elbow and shoulder armor in your jacket, but remove any chest or back protection. However, I think only Alpinestars can answer this question definitively.

    In the Tech-Air Street, there is no need to remove shoulder armor. Alpinestars designed Tech-Air compatible jackets to have shoulder armor that works with the airbag, so you get 'double protection'. However, these jackets that have built-in expansion panels to enable to airbag to inflate properly.

    Also, all versions of the Tech-Air system require removal of any back and chest protectors, so that the airbag can inflate fully. I imagine this is true for the D-Air Smart too, irrespective of its clever marketing.

    Your question highlights why I'm convinced that integrated airbags are better than standalone vests like the D-Air Smart and Tech-Air 5. Much as I'd love the flexibility of an electronic airbag that I could wear with any jacket, there's no point unless the airbag inflates fully in a crash.

    I want a jacket that fits tightly enough to keep any shoulder and elbow armor in place in a crash. Yet a snug jacket will impede an airbag from fully inflating. I concluded that the best option is a jacket that's designed and built for an integrated airbag. Though I’d appreciate other opinions.

    Agreed, the issue is that it looks like both A* and Dainese are moving away from the integral options and offering separate options instead. I also worry about removing armor and relying on a system to function... armor is always there and always works. And then there's the question of weight and ventillation... A* hasn't released a weight on this vest.

    I hope they don't move entirely away from integrated options because these options are better. Thankfully, an Alpinestars representative at February's London Motorcycle Show told me Alpinestars was pushing the integrated airbags as well as the Tech-Air 5.

    Also, the Tech-Air Street and Race airbags have more sophisticated algorithms than the Tech-Air 5. For example, the Tech-Air Street can recognize twenty different accident scenarios, but the Tech-Air 5 can only spot eight different types of accident.

    I think the Tech-Air vest weighs about 1.3 Kg, which is close to what many Level 2 back protectors weigh. You notice the weight when picking it up but not when you're on the bike. I've also handled a D-Air Smart vest, and I would guess it's a similar weight. I have worn more than one type of airbag over the years and found that fit matters more than weight. If the airbag is a great fit, then the weight disappears on the bike. Alpinestars has thought about this because they make the Tech-Air Street and Race in different sizes to match your build.

    There's a useful review on Revzilla that compares the D-Air Smart with the Tech-Air, written by someone who has owned both:
    I agree with the review about the Dainese Smart vest having its D-Air components at the lower back. It seems crazy to have hard parts positioned on your lower back!

    The Tech Air Street won't inflate in the event or a rear end collision while stopped at a stoplight. The Tech Air 5 will. It has one logarithm that is important to me.

    Sorry but that's incorrect. The Tech-Air Street will inflate in the event of a rear end collision while stopped. Alpinestars is specific about this.

    It was the early D-Air Street airbags that wouldn't inflate in this circumstance. The Dainese system relies on a GPS signal and earlier versions wouldn't activate the airbag below a minimum speed, and could switch off when stationary. I believe the 3rd generation D-Air systems are supposed to detect engine vibrations to address this, but I haven't looked into how or how well it works.

    Also, none of the Alpinestars Tech-Air systems rely on a GPS signal.

    Me too! I've been hit by a car in exactly this circumstance.

    I found it was easy to get confused because of the language used by Dainese in its PR.

    In promoting its third-generation airbags, Dainese inferred that these were the first airbags to work when stationary. However, these products were merely the first Dainese airbags that worked in this circumstance. Alpinestars' airbags have always worked when stationary because they only use accelerometers and gyroscopes, and don't rely on GPS. However, the Dainese system uses GPS that only activates the airbag when it detects you are traveling over 10 km/h. Hence Dainese added a vibration sensor to its third-generation airbags; this sensor is supposed to keep the system activated if it detects engine vibrations.

    I don't know about Helite's new electronically-triggered airbag or the In&motion airbag that's used by Klim, Held, Furygan, etc. The Helite system requires a sensor on the bike; this was always supposed to be superior to having sensors in a jacket alone. In&motion says little about the crash conditions that will trigger its airbag, perhaps because it's such a new system and In&motion is still collecting data to improve it.
