Alpinestars A-5 PLASMA chest protector

The Alpinestars A-5 PLASMA Protective Bib is designed to meet the demands of off-road riding, including motocross and supercross. It combines protection, comfort and adaptability thanks to its lightweight structure in Nucleon PLASMA, an innovative composite, and semi-rigid thermoplastic shells, guaranteeing optimum protection while remaining breathable and flexible.

Technical specifications:

- Nucleon PLASMA protective shells: on the chest and back, the shells are designed in semi-rigid composite, CE level 2 certified, mounted on perforated 3D mesh to maximize airflow, offering enhanced ventilation and breathability during long riding sessions
- Independent side wings: The side protectors are designed to adjust separately from the main shell, allowing full adaptation to body movements and offering maximum flexibility
- 3D mesh frame: The faceplate is made from a breathable, flexible material, promoting ventilation while providing additional impact protection, while being comfortable for the rider even in extreme riding conditions

Safety:

- CE Level 2-certified back and chest protection: The bib features CE Level 2-certified chest and back protectors, providing effective dispersion of impact forces. The back, with its thermoplastic - semi-rigid zone, protects critical areas in the event of a fall or accident.
- Nucleon PLASMA viscoelastic material: made from biosourced polymers, this material offers high shock absorption and flexibility in all directions, guaranteeing complete protection in all riding positions.
- Nucleon PLASMA shell lining: holds the structure of the protectors in place, reducing the risk of tearing and premature wear of the material
- BNS (Bionic Neck Support) compatibility: Integrated with shoulder pull tabs for perfect compatibility with Alpinestars BNS neck protection systems

Comfort:

- Adjustable shoulder and side straps: Designed to offer an ergonomic, customized fit, they provide stable, secure attachment while adapting to the rider's morphology
- Removable shoulder padding: Made of soft-touch thermoformed material, this padding offers enhanced comfort while providing extra protection and facilitating rider movement
- Improved ventilation: Nucleon PLASMA ribbed shells promote optimal air circulation, reducing body heat and improving overall comfort, especially during extended runs in high temperatures

Sizes: Available in XS/S, M/L and XL/XXL
