2.5. How to choose and wear the D-AIR STREET SMART CHEST
Equipment must be chosen with attention to the indications and the symbols on the marking.
To choose the correct D-AIR STREET SMART CHEST back and chest protector, refer to the distance between waist and shoulder, as there
is no constant relation with body height.
This is the maximum vertical length, measured at the back, from the waistline to the point in which the shoulder joins the neck. To find
the waistline, stand upright and pass a measuring tape around your waist 50 mm above the iliac crests.
Note: 50 mm is an example that refers to a person with a height of 1.78m, this measurement should be decreased in proportion to the
person's actual height; some examples are indicated in table 3.

Distance above the iliac crests (mm)
To find the D-AIR STREET SMART CHEST most suited to the distance between your waist and shoulder consult Table 4 in the section
(Position and minimum sizes of the areas protected by the D-AIR STREET SMART CHEST)
In order for a protective device to perform its protective action correctly, the body area to be protected must remain efficiently covered.
The D-AIR STREET SMART CHEST is a Protective Device developed to be integrated in specifically designed garments only.
To ensure correct protection, in addition to the measuring of the distance between waist and shoulder (see Table 4), particular care
should be taken when choosing the size of the garment specifically designed with the D-AIR STREET SMART CHEST integrated, carefully
reading the Informative Note provided with the garment.
