Very Comfortable
24 Sep 2025 by Mike
Really comfortable and because it arms itself when you zip it up removes all the faff for an airbag. No subscription, no lanyard and you can replace cartridges yourself. Two little niggles with it.
1. Because the front zip is in the centre you have to clip the chest airbag in place before zipping it up. It is however magnetic so not hard to do.
2. The USB charging port just floats around inside a little pocket on the front.

Great fit and looks good
30 Aug 2025 by Stephen
Unlike some airbags out there this one actually looks like a normal piece of clothing. It’s very comfortable , easy to set up , easy to charge and importantly waterproof!! Ideal for wearing on top of other kit but can be used underneath if preferred. Sizing seems spot on. Very happy with my choice

Great product quality and feel
18 Aug 2025 by Chetan
Arrived in a battered box so looks like it may have been used to return a few times but the actual item was in good condition. I charged it and tried it out and works well. Very easy to put on activate. The back does have a bit of bulk for the canister though.
Overall looks and feels like a really good quality item. Haven't tried it out yet with the bags actually deploying.

Lightweight and easy to use. Best feature is the haptic feedback which physically lets you know when it's armed and disarmed.
One of the better airbag vests out there and one I'll continue to wear.

Fantastic

It's very casual looking and looks like a normal item of clothing. Having had a dianaise airbag vest for 7 years, this is a fantastic upgrade. I have no complaints at all.

I bought the tan canvas version as I preferred the straight, rather than diagonal, zip. I wear it outside my jackets as they are all snug fits.
I’m 6 foot, 40” chest & 34” waist, and have a mix of Large & Medium riding kit. Surprisingly, since this vest sits on the outside, the Medium fits well. Large is waaay too big. The elasticated sides allow plenty of expansion if necessary.
A great advantage of this air vest over the Dainese is that it’s waterproof. Moreover, the Dainese sits high and seems to only come down half way over my chest.
One issue I considered was what to do if I fell over during a biking tour. At that point, the vest is useless unless I carried an extra canister. Or fitted the Alpinestar back armour, which is what I decided to do. Either way, the extra cost has to be considered if you go touring.
Overall, it’s an expensive piece of equipment. Then again, it’s not much more than a quality helmet. Or an annual bike service. And cheaper than an iPhone.

As you get older you don t bounce as well .

Compact and flexible in terms of sizing I hope I never try this out on the road. It s clever and unlikely to deploy unintentionally. No tethering, no requirement for GPS connection and user replaceable canisters. Size L was good for me at a 43 inch chest. Fits both over and under jackets depending on their fit. Excellent service from Sportsbikeshop as we have come to expect.

I hope I never find out how good it is

Tried this after trying Helite Turtle 2 and Motoairbag MAB V4. The Alpinestars is lighter than the Motoairbag and not as cumbersome as the Turtle, once its on you don't know your wearing it, apart from the vibration from the vest letting you know it is on and active. Excellent service from Sportsbikeshop as always

Size Guide & Product Warning
The Alpinestars' Tech-Air® 3 Canvas Airbag System is designed to be worn over a motorcycle jacket but can be worn under the jacket as well, providing effective and practical protection for V-Twin riders, touring riders, urban city commuters and weekend warriors who want to ride protected. Alpinestars' crash detection triggering algorithm has been developed and refined with millions of kilometres of riding data and thousands of crashes; allowing the system to accurately assess when to deploy the airbag ahead of an impact or other dangerous situations, like a lowside or highside crash.
In the event the Tech-Air® 3 detects the start of a crash, the system will inflate the protective airbag in milliseconds, reducing up to 95% of the impact energy transferred to the rider anywhere the airbag protects, which includes the full chest and back. In the event of a direct impact of the rider with another vehicle or obstacle, the Tech-Air® system, is effective for the "first impact!", which means that the system inflates before the rider comes into contact with the vehicle or obstacle.
Additionally featuring a main chassis constructed of stretch nylon canvas, and waterproof ECU and electronics, the slim, self-contained System can be worn under a motorcycle jacket, including an Alpinestars' Tech-Air® Ready jacket, or any leather or textile jacket, providing that the jacket has sufficient space to accommodate the inflation of the airbag.
