Protection
These are not two grades of the same product. One is armour; the other is equipment with a maintenance interval.
A classified plate. EN 1621-2 gives it a level from a measured transmitted force and a type — B or FB — describing coverage. Both are printed on it.
It needs nothing. It does not charge, expire, or cost anything after an impact.
A device. It has a trigger, a gas cartridge or a reset procedure, and a service interval.
It is the only product category on this site with a published maintenance schedule, and the three things to establish before buying one are the same every time: the trigger arrangement, the service interval, and what a deployment costs to put right.
The German market sells equestrian and motorcycle airbag vests under the same word, and several products in that family are published by their own makers for equestrian sport — one of them says “developed specifically for equestrian sport” in its own bullets.
They are real products with real triggers. They were not designed for a motorcycle, and the maker is the one saying so.
If you want protection you can forget about: a certified back protector, with both the level and the type read off the piece.
If you want an airbag: buy it from a maker that publishes the trigger, the interval and the reset cost, and read all three before ordering.
EN 1621-2 level 2 · D3O · breathable and flexible · fits any jacket
A level 2 approved back protector using D3O, published as breathable, flexible and light, with a universal fit the maker states is compatible with any riding jacket.
Best for: Replacing a foam placeholder in a jacket pocket with a certified level 2 piece.
≈ £38 / €30
EN tested · level 2 · harness worn · low weight
A level 2 back protector worn on its own harness, published as EN tested, non-slip and light, sold for motorcycling and for winter sports.
Best for: A rider whose jacket has no back pocket, or whose pocket will not take a certified insert.
≈ €75
Self-contained · worn under any maker’s kit · 60 ms inflation
A self-contained airbag vest with a front zip, published as wearable under protective clothing from any manufacturer, with a stated activation and inflation speed of 60 ms.
Best for: A rider who already owns a jacket and wants an airbag that fits under it whatever the brand.
≈ €190
Overlapping fan-shaped plates · hip belt with hook-and-loop · multi-sport
A back protector built from fan-shaped overlapping plates for mobility, with a hook-and-loop hip belt adjustable for different waist sizes.
Best for: A rider who wants articulation and will check the marking on the product.
≈ £31 / €42
Electronic airbag system · motorcycle-specific
An electronic airbag vest from a motorcycle equipment maker. The listing text itself is minimal — brand, category, colour and size.
Best for: A rider prepared to read the maker’s own documentation, which is where this system is actually specified.
≈ $870 / £700 / €750
A trigger arrangement, a service interval, and a cost after it fires. An airbag is the only product on this site with a published maintenance schedule, and those three figures are what turn a purchase into a commitment.
A tethered system clips to the machine and needs no battery; it does nothing if you forget to clip it. An electronic one uses sensors and needs charging. Each has a failure mode and the maker publishes which it uses.
An insert needs a jacket pocket of the right size holding it flat over the spine. A harness is worn independently and stays in position whatever is over it, at the cost of bulk.
For : Replacing a foam placeholder in a jacket pocket with a certified level 2 piece.
Main strength : Publishes a level, which most protectors here do not
Main limitation : The type — B or FB — is not published, and that is the coverage classification
For : A rider whose jacket has no back pocket, or whose pocket will not take a certified insert.
Main strength : A harness stays where it is put regardless of what is worn over it — no pocket sizing problem
Main limitation : EN is cited without the standard number, so the document is not named
For : A rider who already owns a jacket and wants an airbag that fits under it whatever the brand.
Main strength : Publishes a figure for activation and inflation — the only listing here that does
Main limitation : The trigger type is not stated in the listing text — tethered and electronic behave very differently
For : A rider who wants articulation and will check the marking on the product.
Main strength : Overlapping plate construction is published and it is what allows a rider to tuck
Main limitation : No standard, level or type cited
For : A rider prepared to read the maker’s own documentation, which is where this system is actually specified.
Main strength : A motorcycle-specific system from a motorcycle maker, which is not true of most of this family
Main limitation : The listing text publishes almost nothing — brand, category, colour, size

Head-to-heads already published between two models from this guide or this aisle.
The models here come from the catalogue of this site. Specifications are those published by the manufacturer and on the Amazon product page; prices are what Keepa reported on the date below, and both move. The ranking uses declared specifications, the balance of stated strengths and limitations, and price. No product on this site has been physically tested, and nothing here claims otherwise.

Nothing written into the text below is a current price. Where an amount appears in a sentence, it is the reading taken on the day that sentence was written; what a shop is asking at this moment loads beside the product itself, and that is the figure to go by.
Helmets and riding gear are discounted over and over through the year — hardest of all in the weeks when nobody is riding, which is months away from when most of it is bought — and a struck-through figure on its own says nothing whatever about what the same model was charged at four weeks ago. UniverTrack holds a week-by-week history for every retailer, which means a reduction is judged against a price somebody actually paid rather than one dreamed up for the sale — and it tells you when the moment to buy has genuinely come.
