Motorcycle Airbag Vest Buying Guide 2026

How airbag vests work, the real differences between tethered and electronic systems, CE certification, and what to expect to pay across EU retailers.

How motorcycle airbag vests work

A motorcycle airbag vest inflates a gas bladder around your torso — covering the chest, back, shoulders, and sometimes the collar area — within 60–100 milliseconds of detecting a crash. The airbag acts as a supplemental protection layer over or under your jacket, absorbing impact forces that would otherwise reach your spine, ribs, and collarbone.

The technology is mature. The core question is not whether they work — they do — but which triggering system suits your riding style and budget.

Tethered vs electronic: the key decision

Tethered (mechanical)

A cord connects the vest to the bike. When you are thrown clear of the bike, the cord pulls a pin that triggers CO₂ inflation. Simple, no battery, no connectivity, no subscription. Price: €200–€450 for the vest + €20–€40 per CO₂ cartridge replacement after each deployment.

Main brand: Helite (French, industry standard for tethered systems). Also: Hit-Air.

Best for:

Everyday commuters, touring riders, anyone who wants reliable protection without ongoing costs. Works independently of any electronic system — no software updates, no subscription.

Electronic (autonomous)

Onboard sensors (accelerometers, gyroscopes) detect crash signatures and trigger inflation without a physical cord. No cord to clip and unclip at every stop. Can detect lowside and stationary falls that tethered systems miss. Price: €700–€1,500+ for the vest or jacket.

Main brands: Alpinestars Tech-Air (self-contained), Dainese D-air (integrated into jacket), In&Motion (subscription-based sensor module).

Best for:

Riders who want seamless protection without the clip-in discipline. Note that some systems require a subscription (In&Motion) or are integrated into specific jackets (D-air) limiting future compatibility.

CE certification: EN 13158 and what it means

EU airbag vests are certified under EN 13158:2018, which covers equestrian and motorcycle protective garments. The standard defines two levels:

Level 1 — basic impact protection. Minimum requirement. Adequate for lower-risk riding.
Level 2 — higher impact absorption. Recommended for regular road use and all airbag vests sold for motorcycle use.
Level 3 — the highest level, primarily for high-speed and racing applications. Found in some competition-spec airbag suits.

All reputable airbag vests sold in the EU meet Level 2 as a minimum. When comparing products, confirm EN 13158 Level 2 certification in the specification sheet rather than assuming it from the marketing description.

What to wear it with

An airbag vest is not a replacement for a protective jacket — it is an addition. Most riders wear it:

Over the jacket — most common with tethered systems. Easier to clip and unclip. Looks less elegant but is cooler in summer.
Under the jacket — more common with thin electronic vests like Alpinestars Tech-Air 5. Requires a jacket with enough internal volume. Check compatibility lists — manufacturers publish which jackets their vests fit inside.
Integrated — Dainese D-air jackets and some Alpinestars models have the airbag built into the jacket itself. Cleanest solution but commits you to that jacket.

Real costs: purchase price + ongoing

System type	Initial cost	Ongoing cost
Tethered (Helite)	€200–€450	€20–€40 per CO₂ cartridge after deployment. Otherwise none.
Tech-Air 5 (Alpinestars)	€700–€900	None. Self-contained rechargeable system.
D-air (Dainese)	€900–€1,500+ (jacket)	Service cost after deployment (~€100). No subscription.
In&Motion	€500–€700 (vest)	~€10/month subscription for crash detection service.

Compare prices across EU retailers

Airbag vest prices differ considerably between EU retailers, particularly for Helite products which are stocked by more general motorcycle gear retailers. Electronic systems from Alpinestars and Dainese have more consistent pricing across channels.
