Equestrian airbag vest under or over a show jacket: the real rule
Partager
In the warm-up arena, the question initially seems aesthetic: should your airbag remain visible or sit beneath your show jacket? In reality, it affects the operation of the equipment itself. During a fall, the airbag has only fractions of a second to reach its full volume. Any garment worn over it must therefore be able to make room.
This is where the most common misunderstanding begins: a jacket described as âstretchâ is not necessarily compatible with an airbag. Simply choosing one size larger does not guarantee compatibility either.
The safest rule is simple: an airbag is worn as the outermost layer, over clothing, unless its manufacturer explicitly permits it to be worn beneath a suitable jacket.
Why can a jacket interfere with airbag deployment?
A mechanical airbag is connected to the saddle. When sufficient separation occurs between rider and horse, tension on the tether releases the mechanism, pierces the COâ cartridge and inflates the protective chambers.
AXION Equestrian airbags are stated to inflate in under 100 milliseconds. During that very short period, volume must form around the neck, chest, back, lumbar region, pelvis and sacrum.
If a jacket is too narrow, too rigid or lined with material that has little stretch, it can resist inflation. It can also place sudden strain on its fastening, buttons or seams. The priority is therefore not merely avoiding damage to a show jacket, but ensuring that the operation of protective equipment is not disrupted.
Can an AXION airbag be worn beneath a show jacket?
Yes, provided the jacket is genuinely suitable for use with an airbag and leaves the space required for deployment.
For an AXION Equestrian airbag, a garment worn over it must contain at least 15% elastane. This is an initial material requirement, but it is not sufficient on its own.
Two jackets with exactly the same fabric composition can behave very differently. Cut, lining, shoulder construction, seams, fastening and the way the jacket fits the rider matter just as much.
In other words: 15% elastane is a minimum requirement, not a universal guarantee of compatibility. If the jacket is not presented as airbag compatible or any doubt remains during fitting, the airbag should remain on top.
How can you recognise a genuinely compatible jacket?
1. Your airbag model permits use beneath a jacket
Recommendations vary from one system to another. A combination that works for one model cannot automatically be applied to every airbag on the market. The instructions for your own equipment remain the reference.
2. The jacket is designed or explicitly presented for this use
The word âstretchâ is too vague. It says nothing about the rigidity of the lining or the jacketâs true ability to accommodate a sudden increase in volume.
3. The cut retains enough room when the airbag is fastened
A compatible jacket should not already be under strong tension at rest. If its buttons, zip or seams pull before deployment, there is probably not enough expansion reserve.
4. The cartridge and mechanism are not compressed
The garment must not press on the cartridge, move the housing or trap the connecting tether. Access to the snap hook must remain straightforward in the saddle.
5. No hard or sharp object covers the inflation areas
Avoid brooches, pins, protruding metal accessories, very tight belts or rigid objects in a pocket against the airbag.
Should you buy the jacket one size larger?
Not necessarily. A larger size can provide more room, but it does not make rigid material more elastic. Conversely, a jacket specifically engineered to accommodate an airbag can retain an elegant cut without looking oversized.
Try the complete outfit with the clothing actually worn in competition: fasten the airbag, add and close the jacket, raise your arms, open your shoulders, adopt a two-point position and lean forward as you would on landing. Check that no excessive tension appears across the chest, back, fastening or mechanism.
Can an incompatible jacket tear?
Yes. A fastening, lining, button or seam may fail if the garment cannot accommodate inflation. But the essential question is not simply whether the jacket survives: it is whether the airbag can deploy as intended. A garment can remain intact while still imposing too much restraint.
What about a padded jacket, coat or waterproof?
The same reasoning applies. A loose padded jacket can compress some areas. A waterproof can look roomy while being made from almost non-elastic material. A coat can obstruct the cartridge or catch the tether.
In winter, the simplest configuration is usually to wear warm layers beneath the airbag and keep the airbag as the outermost layer. Cover it only with an explicitly compatible garment.
Is wearing the airbag on top less elegant?
It often used to be, simply because most protective equipment was designed to disappear. AXION Equestrian was born from a different idea: if an airbag should be worn every ride, it can also become a deliberate part of the outfit.
Technical fabric, a fitted line and hand-applied Preciosa crystals allow the airbag to be worn over a shirt or jacket without looking like a purely utilitarian addition.
Airbag and rigid body protector: do not confuse them
A mechanical airbag provides its inflatable protection when it deploys. A rigid body protector provides inherent protection before any fall. In disciplines where the rules require a protector meeting a specific equestrian standard, a conventional airbag does not automatically replace it.
The check before every ride
- the airbag is the correct size and fully fastened;
- the authorised cartridge is intact and correctly screwed in;
- fabric, seams, tether and mechanism show no visible damage;
- any garment worn over it is compatible and compresses no part of the system;
- the saddle strap is correctly installed;
- the tether is connected once in the saddle and allows normal movement.
Under or over the jacket: what should you choose?
Over the jacket, the airbag remains independent of clothing changes, visible and easy to check. This is the reference configuration whenever a garment is not explicitly suitable.
Under the jacket, it retains a more traditional competition silhouette, provided the airbag model permits this use and the jacket genuinely meets every compatibility requirement.
To check the fit, use the AXION size guide. You can also explore AXION Equestrian airbags, CE marked, whose EU type examination is carried out by ALIĂNOR Certification, notified body no. 2754, using NF S72-800:2022 as the technical reference.
