Alpinestars A-5 Plasma Chest Protector

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 is a composite construction and has a central semi-rigid thermoplastic zone on a Nucleon Plasma back protector for greater impact force dispersion in a critical area
Protectors have an adaptive fit that follow the body’s contours for comfort and freedom of movement
Nucleon Plasma is a viscoelastic material engineered from bio-based polymers and formed into a structure that is pliable in all directions while maintaining the ability to dissipate impact energies
Lightweight and ventilated, this knee 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
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
The perforated 3D mesh chassis also offers additional protection against tire roost
Bionic Neck Support (BNS) compatibility via the BNS shoulder pull tabs
