ALPINESTARS A-4 PLASMA CHEST PROTECTOR

Alpinestars A-4 Plasma Chest

Alpinestars is proud to present you his new chest protector offroad / mx, the A-4 Plasma Chest.

Designed with an anatomical profile suitable for all off-road disciplines, the Alpinestars A-4 PLASMA chest protector combines a semi-rigid thermoplastic polyhedron chest shell with a protective Nucleon Plasma back.

The combination provides effective protection while remaining lightweight, breathable, comfortable, and perfectly fitting to support the rider's every movement.

Material:

• Biotechnological construction using USDA-certified bio-based viscoelastic materials, combining performance, durability, and environmental friendliness.
• Perforated 3D mesh chassis provides maximum breathability and additional protection against spray.
• Soft, ribbed internal lining reduces contact points with the skin while promoting airflow and comfort.
• Chest shell inspired by geodesic structures: a design based on interconnected polyhedra offering high structural strength, extreme lightness, and maximum ventilation.

Lining:

• Soft, tactile lining provides a pleasant feel against the skin while maintaining the structural integrity of the protectors.
• Integrated ribbed ventilation channels for superior airflow and reduced overall system weight.

Ventilation:

• Advanced ventilation system with a highly perforated structure for optimal airflow in all riding positions.
• Lightweight and ventilated Nucleon PLASMA material, ensuring efficient dispersion and absorption of heat and impacts.

Safety:

• Nucleon PLASMA Level 1 back protector (EN 1621-2:2014).
• Bio-sourced viscoelastic material, providing high impact energy absorption and multidirectional flexibility.
• A-4 PLASMA Level 1 chest protector (EN 1621-3:2018):
• Innovative geodesic structure for an optimal balance between lightness and strength.
• Adjustable and detachable rib and shoulder pads for extended coverage and enhanced protection against projections.
