Very good only negatives are the weight and breath

No electronics = great.
Two airbags one for front and one for the back. For summer use you need a very light mesh summer jacket.

Top quality layer of protection
03 July 2025 by Matt H
This seems to be a great airbag vest, offering comprehensive protection to mitigate the effects of potentially life changing injuries.

Attach and detach could do with being easier - The D ring on the bike and carabiner on the vest could both be bigger and easier to feel, as you can't see behind you with a helmet on.

It is, by nature, not very breathable and pretty heavy. Once on the move, you don't really notice though. It's a shame that the mesh jacket that it can attach to is difficult to find in the UK - I've ordered one from Italy for the hot weather. The safest gear is the stuff you wear.

Pocket is good. Another one on the other side would be nice.

Sizing wise, I was in between L/XL and XXL/3XL according to the website, but the 3XL was really big in real life - The L/XL has plenty of space.

Overall very good. Riding bikes (especially if you do it enthusiastically) is dangerous. If I come off, I guarantee that I'll be glad that I'll be wearing this.

Air Vest Safety

Great product for all round body and neck protection. Comfortable to wear over your existing jacket. I have worn it in 30 degree heat and when on the move could feel cooling air flow though the mesh. Highly recommend this product and great service from sportsbikeshop.

It’s there to do a job. It’s quite heavy and hot though. I put up with it even in this hot weather because if you do ever hit something, this one will give you a better than average chance of protection.

Good quality airbag jacket
20 June 2025 by Mark A
I bought one of these for myself and one for the wife. It’s quite hard to give this a review on how effective it is without crashing, but given the positive review by Bennett’s on YouTube, it seems to be one of the most protective jackets available. It seems well made and the sizes seem to be true to size, at least for us, it is quite bulky, so on a hot day, If I am just going for a bimble on the moors I may leave it at home, but for faster more adventurous riding I think I will be wearing it all the time. I did um and ar about buying an airbag jackets, I do wear decent kit, but do like to just swing my leg over the bike and just ride. Modern biking does seem a bit too much of a palavor sometimes with riding modes, gps etc. but you just throw this jacket on like a waistcoat and clip it on, which is why I went for a manual jacket rather than an electronic one which may need software updates and battery charging which I just can’t be bothered with.

MOTOAIRBAG MAB V4 Modular Airbag Vest - Grey - 2XL
17 June 2025 by Gary T
I'm 6'6 tall, so this vest fits over a Big Mans RST jacket with winter gear on!! Also for summer use it has pockets to fold the jacket to make it smaller!!
It's well made, slightly heavy but if this vest protects me from a serious injury I put up with that.
Hopefully it will never have to be used but some how I doubt that on the British Roads of today with the twats behind that wheel!!!!!

This product scores well for safety. Easy to use a
09 June 2025 by Sarah B
Although I have not had to experience the product working as yet i.e. it has not had to inflate, I have viewed my partners jacket inflating and it was effective. The sizes and shape fit better than some of the other air vest products I tried on an viewed and offers more body protection. It is comfortable to rid in as it is not too long, again some of the other product are long in the back and push up when riding from the seat, this one does not. I also still have a good range of head movement when riding which some of the other jackets did not allow as much for.

Comfortable
10 May 2025 by Gordon R
Looked at a few reviews before purchasing this air vest. Feels heavy ish when you put it on but when on the bike doesn't feel heavy actually comfortable. Can stand up on the bike when tethered. Is a bit pricey but if it does the job in the event of an accident must be worth it.

Hopefully a waste of money!
05 May 2025 by The C
The best feels really well made. I normally wear an XL jacket and originally went with the L/XL size. When this arrived I found it to be a bit tight, even at full ‘extension’ so I ordered the 2XL size to store and the difference for me was night and day, so stayed with the larger size.

Sportsbikeshop were OK with the change as expected.

The vest is quickly forgetting about when riding, you just have to adjust your on/off procedure slightly to remember to hook yourself in and out.

There is another zip inside the vest that doesn’t seem to get a mention, I can only guess it’s for an additional layer, but it’s a bit of a unknown at the time of writing this.

So far all good, but as I say in my title - I hope it’s a waste of money and I never have to use it!!

A need for riding
12 April 2025 by Jason B
Got after searching or the other Airbags on the market, what draw me to Moto Airbag, is you can recharge the vest and doesn't need to be returned to manufacture , you get used to have the draw cord.

It's peace of mind
11 April 2025 by Jim
As someone who enjoys the thrill of the open road but would still prefer to keep all my limbs attached, I decided to invest in the MOTOAIRBAG MAB V4 Modular Airbag Vest aka, my new high-tech guardian angel in black.

First off, this thing looks seriously cool. It s got a sleek, tactical vibe that says, Yes, I m responsible but I still look like I could ride into a Fast & Furious movie.

Now let s talk safety. Wearing this vest gives me that warm, fuzzy feeling the kind that says, If gravity wins today, at least I ve got a fighting chance. It s like having a secret bodyguard who only shows up when things go sideways literally. The mechanical trigger system is brilliantly simple: no batteries, no recharging, no software updates. Just good old-fashioned cable-powered peace of mind. Tug the tether, and boom instant marshmallow mode.

And yes, I did spend five minutes pretending to crash into pillows just to hear that satisfying poof. You can t blame me this thing is basically a life-saving inflatable jacket, and I had to test the drama. (It passed.)

Jokes aside, this vest is a serious game-changer. As motorcyclists, we accept a certain level of risk but that doesn t mean we shouldn t stack the odds in our favor. The MAB V4 adds that extra buffer of safety without turning you into a robot or sacrificing comfort. Fits nicely over my jacket, doesn t restrict movement, and gives my girlfriend one less reason to worry every time I head out.

In summary:
Stylish
Practical
Might make you feel like Batman
Hopefully never needs to activate but if it does, I know it s got my back (literally).

Highly recommend to any rider who values their spine, ribs, and continued existence. Ride safe, inflate only when necessary!

Airbag peace of mind.
10 March 2025 by Philip M
Had to choose between an under jacket or over jacket airbag. I was leaning to the under jacket variant but as soon as I tried on this airbag I knew it was the one. It fits perfectly and I don't even feel it's there. Adds wind protection too therefore adds warmth. I have a textile jacket and a leather jacket and fits perfectly on both. I went to the Glasgow store with both my riding jackets and tried different airbags. The staff were great and their advice was invaluable.

Glad I bought this
20 February 2025 by Tim C
Hopefully, I'll never have to experience this going off, but initial impressions are that this is well made and offers lots of adjustments to get a good fit. I bought this off the back of Bennetts reviews as it offers a good deal of protection. It is a bit heavy, but you don't really notice when you're wearing it. Overall, I'm happy with this purchase.

Happy so Far
12 February 2025 by Mark W
Having worn a back protector for many years and riding almost every day I finally went for an air jacket. I opted for the MotoAirBag V4 due to its CE approval and long-term European market leader.. although its fairly new to the UK they are very popular in Europe and I've seen them many time abroad... I tried on a demo in the shop and got the right fitting, it looks stylish, plenty of adjustable straps/zips.. it feels heavy but once on you don't notice the weight and its a lot more comfortable than the back-protectors... fitting the lead to the bike was easy although the rear coupling is a bit awkward as you have to reach behind and find the coupling, time will tell if this gets on my nerves...
Overall I'm happy, great looking vest, feels good, happy with both front and rear air bags (hopefully I will never use)... so far so good..

Great bit of kit
29 January 2025 by Anonymous
I'd been considering airbags for over a year. After watching the Bike Social video comparing their safety ratings I wanted to try this on for fit.

It's comfortable, I thought I'd have to go a size larger to fit over my clothing but I don't and there's still room for more clothing beneath. I've worn it over leather and fabric jackets and in the summer will probably wear over the MAB sleeves… which I'm going to buy separately.

I've not accidentally triggered it by getting off the bike and haven't yet inflated it.

Much more comfortable than my level 2 back protector I used before.

Was looking at an airbag vest for sometime, doing lots of research with all of them, the V4 stood out as it's EN approved unlike a lot of them, it has a genius tether system so will go off if your rear ended.
Luckily haven't had to use it, but looking at the videos it offers lots of protection, thanks to it 2 separate bladders.

The MAB V4 is an airbag vest, equipped with two synchronised airbag devices with Fast Lock technology, to wear over your jacket. Made from high tenacity polyester, it is supplied with a ring to connect to the motorcycle seat. The airbag comes ready activated and is reusable.


The MAB V4 features 2 airbag systems. A rear airbag for full-width back, sacral and cervical protection, and a front airbag for chest, neck and abdomen protection. The Fast Lock technology manages accident recognition in a complete and reliable way, with an 80 millisecond inflation time for both airbag systems to inflate with 25 litres total capacity (15 litres in the rear airbag, and 10 litres in the front airbag).
Once the MAB V4 is activated, it can be recharged in a few minutes using the recharge kit.


Fast Lock is the evolution of the activation cable. Internally it has an analogic accelerometer which can detect accident situations like a car's safety belt. It recognizes any type of accident upward of 5km/h. Fast Lock reacts in less than 5 milliseconds and activates the airbag.

Fast Lock is connected to the synchronisation system, which allows the airbag to be activated closer to the impact situation. For example, in a frontal impact, the front airbag is activated early and the rear on is activated after a few thousandths of a second. For rear-end collisions, the rear airbag is deployed before the front one.

The MAB V4 is equipped with an anti-accidental activation system. Before activating the airbag system, it is necessary to extend the cable, overcome the elastic recoil force of Fast Lock and apply a load of 15kg.
