The A-5 Plasma Chest Protector is designed for optimal protection and comfort. Chest and back protectors are mounted on a highly perforated 3D mesh for airflow and breathability. The side wings are independent from the main semi-rigid chest protector outer shell to ensure a fully adaptive fit.
The back protector features a composite construction and has a central semi-rigid thermoplastic zone on a Nucleon Plasma back protector for greater impact force dispersion in critical areas. The protectors have an adaptive fit that follows the body’s contours for comfort and freedom of movement.
Nucleon Plasma is a viscoelastic material engineered from bio-based polymers, formed into a structure that is pliable in all directions while maintaining the ability to dissipate impact energies. This lightweight and ventilated protector offers strong impact force dispersion and absorption while ensuring maximum coverage area in all riding positions.
Equipped with adjustable shoulder and side straps for an optimized performance fit, it also features removable soft tactile, thermoformed shoulder padding for enhanced rider comfort. Liners on the Nucleon Plasma chest and back protectors maintain the integral structure of the protectors and reduce the risk of any material tearing.
The Nucleon Plasma protectors are ribbed for airflow while also reducing the amount of material that is in contact with the skin. Additionally, the perforated 3D mesh chassis offers extra protection against tire roost. Bionic Neck Support (BNS) compatibility is available via the BNS shoulder pull tabs.
