Hi All,
Wondering if anyone on the forum has tried both and what their thoughts are.
I was originally leaning towards the Dainese but I like the shoulder protection of the Tech air 5.

Anyone know someone that had an accident wearing one?
Any false deployments?

Thanks!

I’d rather have the Tech Air because of the shoulder protection as well.

Just ordered the Tech Air 5, picking it up in the next couple of days, will report after some use. But yeah, my main deciding factor was the shoulders protection.


This guy crashed while wearing the tech air and the impact was on his shoulder and collarbone. So if he was wearing the Dainese one, he wouldn't be so happy I take it.

Cheers

Hi guys.

So I received the Alpinestars Tech Air 5 last week and managed to have x2 20 minutes rides in it, so here's my review so far, given the very limited experience I got (it's currently snowing in London, so I'm not sure when I'll have another chance to ride...)

My measurements and fit: I'm 5'9 and 68kg, so quite skinny, but with some muscle, if I dare say so myself (I'm a BJJ instructor in my spare time). My chest measurement is roughly 102 cm, so I checked the Alpinestars size guide here and went for size M. The airbag fits quite snug in the armpit area, perfect on the shoulders and quite loose on the belly part with the back protector sort of sticking out backwards. However, that's all when standing up. When in tuck down position on the bike, the whole thing feels very good and snug, apart from those armpits. The material in the armpits is quite stretchy though, so after the short rides I had I don't see it being a problem.

Fit with my jackets: My main riding jacket is Oxford Route 73 in size M and I think it's perfect for this air vest as there is some movement around my chest and shoulders, but it feels very comfortable as a package. I have removed the back and shoulder protectors from the jacket of course. The back protector from the air vest actually sticks out quite a bit, so it does look like I'm wearing one of those race suits, so do bear that in mind. I am yet to try the vest with my summer jacket, but it's a bit more loose than my leather one, so I think it should be good too.

Weight: The air vest is surprisingly heavy, it feels like you're wearing a backpack with a laptop in it, but a very comfortable backpack, so no complaints there.

Ventilation: I must say I was expecting a bit more ventilation from it. Reading the reviews and all, I thought that the mesh material will make is very breathable. However, the actual air bag under the mesh material is anything but breathable of course, so I'd expect it to be quite warm in the summer. Riding in the English winter it felt warm, so there's that.

App and updates: I like the app, it's very straightforward and quite informative. Not sure I'll be using it to record my data, but it's quite easy to use. The fist update took a while, but the next was fairly quick, so no complaints there.

Battery and turning it on: I haven't ridden it enough to gauge the battery life, but I know that the charge time is nothing quick, but not too long, so I'm happy with the charge time. One of my slight fears was that I'd leave it turned on when not in use and that the battery would die for my next ride. However, firstly, the buckle is very easy to keep open when storing the air vest and secondly, if the jacket senses no movement for a period of time it turns off and stays off.

Overall I'm very happy with it so far, but we'll see how warm it will get in the summer. After all, it can't protect me if I'm not wearing it :)

Hope this helps someone to make a decision

Cheers

Thanks a lot for long description. To be honest this makes me think more towards Dainese - mainly due to the weight. I like to ride with Kriega backpack instead of bag behind me and extra weight on my back + me sweating - I would feel uncomfortable around people : / I have a strange question - do they have a lifetime? After 5 years it's not usable for example? You know... the internal structure of the fabric or something.

Post factum: Wow, I didn't ask nonsense. Here is wtf-480 pages instruction for Dainese and on page 35 is information to check it with the service every 3 years.

@Timur A Appears the Alpinestars Tech Air 5 is about 4 lbs... is that sound correct?

To make it equal but overall everyone is a winner having any vest I searched for Alpine details:

page 16 Two years is the maximum recommended period between inspections, however if the airbag vest is used extensively, then the recommended inspection and service interval is 6 months to 1 year

Even if serviced regularly, there is the possibility that after 10 years the system will not function within the envelope of protection.

10... in ten they will be made light, smaller and everyone will change them for sure but nice they mention so long time.

Yes, that's right actually. However, when not riding the whole weight is at the back, so you kinda feel it worse. However, on the bike it's a lot better. As an example, I use 15 lbs weighted vest when working out, but it's a lot more balanced. Don't get me wrong, the Alpinestars Tech air 5 is not heavy, I just expected it to be lighter, that's all. Googling Dainese air jacket, it's also 4 lbs and I would also expect the weight to be at the back, so this shouldn't be any kind of deciding factor imo

Yes, the manual says service every 2 years. Also there is some warranty where the first few times service is free or something like that. Additionally I understand that replacing the air bad and the cartridges and repairing the "brains" of the vest is actually cheaper than buying a new vest, so in theory it should serve you well a very long time provided you service it regularly. Plus software updates are quite regular now, so you are getting it updated through time. And in 10 years, get a new and updated version I guess.

And also I see the advantage without any subscription. At first I saw some other brands to pay monthly and I thought - ok, I can pay during summer, nice, but no, if you don't pay you have to give back the "computer". Totally stupid and for sure I want Alpine or Dainese [Helite is in subscription, RST, IXON... they use the same supplier who wants cash monthly]. Truth to be told, they will inflate even if not paid but still, the business logic not for me.

You know what? I found now information about limitation of the vests above 2000 m / 6500 ft. @Timur A may I ask for occupy your free time and have a look in your manual to prove it? I mean you have Alpine Start Tech Air. Thanks.

First thing: "
On page 9 of the manual is a section titled "section 4. Limitations of use". It takes up the bottom half of the page, and lists all the things you are NOT supposed to do to/with your airbag vest. They are all printed in bold red type. The very last item says:
"WARNING! Do not use the system 2000 meters above sea level as low pressure may damage the internal battery"... "
And

"
the product specialist at Alpinestars USA for the TechAir 5 (I first called, but was told he was on the road all week). I asked him about the altitude warning in the manual. This was his reply to me:
"The Tech-Air 5 will function as designed at any altitude. Elevation will not affect the system’s performance in detecting crash scenarios or deploying and providing essential rider protection whatsoever. In fact, the thinner air actually works to the system’s advantage. Prolonged or perpetual use of the system above 6,500 ft can over time effect the overall battery life. However, this happens at a very slow rate over years, not days or weeks, and given the 30 hour battery life when fully charged, detecting any loss of battery life is imperceptible. You can use your Tech-Air 5 at altitude without any worries of it not working properly."
"

So ok, just a false flag :) I believe. But you know, why to print it.
The reason why I bothered was my plans to visit Alps, Austria, Switzerland... mountains - all is above 2 km, that's why I mentioned ;)

hey hey hey, again this topic :D They opened me moto shops :love: and I could finally touch, wear them. Wow, I didn't expect my impression would go like they did.

Those who hates my long posts: AlpineStars is great, surprisingly light and comfortable - winner! Dainese shocked me with its tightness and pain in the middle of back from the gas chambers - not bad but 2nd place. Both are too "aggresive" in pushing on my armpits. I can't imagine to wear them without thermoactive underwear.


AlpineStars - size M
Arm covers - you really don't care about them, they are not noticable to be honest and yet you get extra protection 👀
43147

wow it's so light! I don't believe it was without gas units.
Big minus for this part - the internal pillow was rolled and didn't fill this trianangle area - keep in mind to check it - I used fingers to align it back. Although the high pressure wouldn't bother and fill it in no time.
43148

Zipper is fantastic :D So easy to zip, very pleasing.
My jacket is size 50 without the back protector. Look how it offsets? Is this the word?
43149

43150


Dainese - size M
very nice material, the internal chambers are a sort of... empty tortilla / flat sponge with plastic cover - but no impact on anything else, just how Dainese patent works under fingers. I could feel it's heavier.
43151

There is this strange feeling of missing the... arm covers :D Definitely it's tight. I get why they say - ride it outside and without anything else. However beneath is the same feeling so up to you what you want to destroy - only the vest or both pieces of cloth. :p
43152

Definitely less offset... BUT I was feeling two hard cucumbers hurting my back just under my shoulder blades - NOT COMFORTABLE AT ALL 👀 👀 - this is the biggest reason I already knew in my mind Astars is the winner... this was unexpected how much I felt them and I was having a riding position. Hm... hmmmm.
43153


OK, this is my personal view, no guessing and trying to make false statements.
My verdict is - if you buy me - please Astars - I would NOT care about the big turtle on my back - to be honest my worry about the Kriega R20... nea - loose the holders.
Definitely make sure you have enough space under the jacket although again... if it explodes you are really f... and better to be glad you're surived with the vest on.
Consider the push on armpits - it's like so so... I wonder my 7 hour ride with that :unsure:🙄

If I change a job - I buy myself Astars, if not - I will invest in D3O or Revit Level 2 protectors.

Btw. There was a guy with 3 days old new Multistrada with full packet - 💘 BELISSIMA 💘 and a nice girl with older Ducati Monster - but she didn't like me I think haha, not even wave a hand. No worry, I have my Beloved Girlfriend :p

Very good write up, @Grossi.BP

The uncomfortable armpit liner is a lot less uncomfortable when you're actually riding, I hardly notice it to be honest. Same with the weight of the vest (I know you said it was light, but it's still something).

A quick update on my Tech Air 5, it's doing very well and I wear it a lot, it's a habit of putting it on before the jacket now, so it's great! The A-stars support is a little too keen though. I'll elaborate a little:

I had trouble connecting the system with my phone app, basically it took 4-5 attempts each time before the app could see the vest. I asked Astars support what could be the issue and after confirming that I have the latest upgrades (they come once every couple of months I find), they asked me to send it back to the shop where I bought it, so that they get it back in the factory to check. It was a pain, but I sent it and was without the vest for 2 weeks. Riding without it felt like riding in a T-shirt, honestly, you don't notice the weight until it's gone! Anyway, when the shop called me to collect it, they said that A-stars didn't find any faults with it, cleaned it and sent back, charging the shop the shipping fee! They didn't ask for any of that payment off me, but still, I think they overreacted a little. I later found out that the problem was my phone, not the vest. The phone is going a bit crazy with Bluetooth, so that was the problem....

Anyway, still very happy with the vest!

@Ed K I tried them only. I didn't buy anything yet. Astars is a vest, Dainese likes to use a jacket word. Is this what you mean?

@Grossi.BP The Tech Air “Compatible” jackets, like this one…


Any concern about putting the Tech Air under a jacket that might not be compatible?

@Timur A Thoughts?

Aa... sorry, this specific jacket was not in my interest yesterday.
But now I've just put on my RST TracEvo III leather jacket size 52/UK42 and I could fit the vest underneath. The elastic material allows to fill "area" of my small fist (around 3,7 inches) more or less. RST is not ultra tight, I can still walk normally in that suit. Probably some high end Dainese is not good - but they offer for 4k € already included so out of topic. More money-friendly leathers if you are not filling totally each corner of the jacket will work.

They say you need at least 4 cm give around your chest, I've got maybe double that, so I'm not worried. My jacket is not compatible per se, but I'm not worried about the best blowing up, hopefully it'll give me a nice and gentle hug :giggle:
