8. Compatible outer garment
The Tech-Air
®
5 System must be used with an outer protective garment as the vest is not
abrasion resistant. It is generally recommended to the user to choose an outer protective
garment so that, when worn over Tech-Air
®
5 System, it does not cause discomfort and does
not prevent the functionality of the System.
The System can be used with any abrasion resistant garment that covers the upper body
that is designed for two wheeled motor vehicles provided that the garment has sufficient
space to allow for the expansion of the airbag after the deployment.
Alpinestars offers many Tech-Air
®
compatible outer garments (such as Tech-Air
®
Compatible
1 and 2 piece suits, jackets, and the new generation of Tech-Air
®
Ready garments, both of
which are specifically designed with stretch panels to accommodate the volume of the
inflated airbag after deployment).
Follow the procedure described below to check if your garment is compatible with the
System. Remember to ensure that you select an outer garment that has the proper fit
and should any protectors be present on such garment, that the protectors are correctly
positioned. If the garment you have chosen is a leather garment, it is highly recommended
that it has stretch panels to accommodate the inflated airbag after deployment.
Upon inflation, the Tech-Air
®
5 System’s airbag covers the shoulder, chest, ribs and fullback
area, accordingly the System must not be used inside of a leather suit or a 2 piece leather
suit, unless such leather suit or 2 piece leather suit has sufficient space to accommodate
the inflation of the airbag, as shown below, and it’s not too tight in the crotch area in order
to prevent discomfort in case of deployment.

The Tech-Air
®
5 System must ALWAYS be used with a correctly fitting
outer garment of the user’s appropriate body size. Use of the System
with the incorrect size of an outer garment, or not compliant with
the size check recommendations above, may result in the System
malfunction or failure and injury, including severe injury and/or
death.

IMPORTANT!
When the System is used with an outer garment, other than those
specifically designed for Tech-Air
®
Systems by Alpinestars, the user must
verify if the outer garment provides a sufficient inner volume able to
contain the deployed airbag as follows:
1. Measure the circumference of the chest
2. Measure the garment width on the chest region
