In particular the D-AIR STREET SMART CHEST protective device:

gives airbag protection of the chest when triggered.

Covers the central area of the back with a composite protector (CB - Central Back), central protector covering only the central area
of the back, this type of protector does not offer protection in the shoulder blade area.

helmet movements
