TYPE OF PASSIVE BACK PROCTECTORS
The following information will help you to understand which type of passive back protector
(among different types of back protectors) is actually installed inside your System.
The System is equipped with a passive central back protector (CB)
CB = Central Back protector, which provides protection to the central back
EN 1621-2:2014 provides two performance levels of protection: Level 1 and Level 2.
Level 1 protectors have a lower performance protection level, however are more lightweight.
Level 2 protectors have superior performance protection level, however may be thicker and
heavier.
The protector integrated into the System is a Level 1 passive central back protector

Sizing & fitting info regards the back protector integrated onto the System
Back protectors are certified to EN 1621-2:2014 are sized by ‘Waist to Shoulder length,’ as
this gives the best representation of back length. Waist-to-shoulder length is the length
measured on the back from the waistline to the junction of the shoulder to the neck at the
highest point, as shown in the protective equipment pictogram.
The System is equipped with an integrated back protector that is not removable from the
airbag vest nor may the back protector be modified.
The size of the back protector has been selected by Alpinestars based on the sizing and
function of the System. Notwithstanding one single size back protector cannot fit all body
dimensions (height and shape). Accordingly, when selecting the System check that the
System’s integrated back protector is correctly fitting. A correctly fitting back protector
must not be touching your neck when you tilt your head backward. If the back protector
of the System touches your neck when you tilt your head backward, this is a sign that the
back protector of the System is too big and may interfere with the helmet, resulting in a
dangerous riding condition. If this is the case the System is unsuitable for you and must
not be used by you.
CENTRAL BACK PROTECTOR DOES NOT PROVIDE SCAPULA PROTECTION.
USERS SHOULD BE AWARE THAT NO BACK PROTECTOR WILL PROVIDE
COMPLETE PROTECTION AGAINST SPINAL INJURY AND NO GUARANTEES,
WARRANTIES (EXPRESS OR IMPLIED) ARE MADE REGARDING THE
PROTECTOR’S ABILITY TO AVOID RISK OF SPINAL INJURY.
