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.

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

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.

Hopefully a waste of money!

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

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.

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.

Description
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.
