Alpinestars A-5 Plasma Chest Protector — M/L, Men's

Lightweight, ventilated chest and back protection designed to deliver broad coverage, superior impact dispersion and a close adaptive fit.

• 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 and freedom of movement.
• The back protector is a composite construction with 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 follows 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.
• Equipped with adjustable shoulder and side straps and removable soft tactile thermoformed shoulder padding for enhanced fit and 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; protectors are ribbed for airflow while also reducing skin contact.
• The perforated 3D mesh chassis also offers additional protection against tire roost and helps keep the protectors ventilated.
• Bionic Neck Support (BNS) compatibility via the BNS shoulder pull tabs.
• Back protector EN 1621-2:2014 Level 2. Chest protector EN 1621-3:2018 Level 2.
