For Horse Riding




If a rider forgets to release the coiled wire when dismounting the horse, will the airbag activate?

Quite a strong pulling force is required to activate the airbag.
When dismounting, the rider may feel a strong tug and realizes that he/she has forgotten to disconnect the one-touch release.
However, be careful not to dismount a horse forcibly to avoid unnecessary activation.
Always disconnect the one-touch connector before dismounting a horse.

Once the airbag is activated and inflated, can it be reused?

Yes, it can be reused over and over again provided it has not been damaged.
Simply replace the gas cartridge using handy tools attached to the jacket.
If it is damaged, consult with an authorized dealer for a maintenance check.

How long will the airbag system last?

The up-and-down movement or horse-excretions may cause the deterioration of a key ball, coiled wire or airbag tube.
A maintenance check is recommended at least once a year, depending on frequency of use or activation.
An additional or replacement key ball set and coiled wire is sold separately.
