Alpinestars A-5 Plasma chest Protector

Anatomically profiled for all forms of off-road riding, including Motocross and Supercross, the A-5 Plasma chest protector features Nucleon Plasma composite shells and semi-rigid thermoplastic chest and back protectors designed to be lightweight, breathable, comfortable, adaptive and protective.

Level 2 CE certified back protectors are mounted on highly perforated 3-D mesh for superior airflow and breathability.

The side wings are independent of the main outer shell of the semi-rigid chest protector to ensure a fully adaptive fit.

The CE Level 2 certified back protector is a composite construction and features a semi-rigid thermoplastic core zone on a Nucleon Plasma back protector for increased dispersion of impact force in a critical area.

The protectors have an adaptive structure that perfectly follows the contours of the body for superior comfort and freedom of movement.

Nucleon Plasma is a viscoelastic material made from biologically derived polymers and formed into a structure that is flexible in all directions while maintaining the ability to dissipate impact energies. Lightweight and highly ventilated, this knee protector offers strong impact force dispersion and absorption while ensuring maximum coverage area in all riding positions. Eco-friendly and sustainable USDA certified bio-based impact absorbent material.

Featuring adjustable shoulder and side straps for an optimized performance fit.

Removable soft and tactile thermoformed shoulder padding for increased rider comfort.

Linings on the chest and back protectors maintain the integral structure of the protectors and reduce the risk of material tears.

The liners are ribbed for superior airflow while reducing the amount of material in contact with the skin.

The perforated 3D mesh frame also offers additional protection against tire deposition.

Compatibility with Bionic Neck Support via BNS shoulder tabs.
