Alpinestars Bionic Youth Back Protectors are the best way to protect the crucial backbone area on your child when they are competing in motorsport. Impacts can be dangerous and even fatal if the body is not protected with a Alpinestars Bionic Youth Back Protector and other CE rated protective gear.
CE Level 2 Bionic Back Protector
CE Level 2 protection means this protector offers double the impact performance of a CE Level 1 protector
CE Level 2 Impact performance (under 9kN of average transmitted force) in accordance with EN 1621-2
DFD (Dynamic Force Dispersion) Technology: this protector is reduced in thickness and in weight: 15mm thinner and 130g lighter than previous models
Ergonomic 5 plate construction contours to the natural curve of the back.
Plates lock to lessen over extension of the back
Construction allows excellent shock absorption, even in repeated impacts, but allows a thin, light, and substantially breathable core
The airflow has been designed that even if the protector is pressed hard against your body, air will still flow through from the top to the bottom
Adjustable shoulder straps
Wide waist belt with thermo-formed protection at the sides
One size fits all
