Made from premium materials and featuring an ergonomic, lightweight design, the Alpinestars Nucleon PLASMA protective jacket offers superior protection thanks to Nucleon PLASMA reinforcements on the shoulders and elbows. Its breathable stretch mesh ensures optimal ventilation and a close, body-hugging fit. Compatible with the Bionic Neck Support (BNS), it combines comfort, safety, and durability for off-road riding.

This jacket features a removable chest protector consisting of a thermoformed outer shell and an EVA protector mounted on a 3D mesh to offer optimal protection that combines lightness, adaptability, and flexibility, as well as exceptional airflow and breathability.

The back protector, featuring Cell technology, is designed with a strategically positioned flex groove to perfectly follow the curvature of the spine for maximum adaptability.

The back protector is equipped with a removable puck washer for compatibility with the BNS neck brace.

The Nucleon PLASMA elbow and shoulder protectors are mounted on an ultra-breathable stretch mesh structure for a better fit and improved comfort while riding.

The padding is strategically positioned on the biceps and chest for enhanced protection against tire spray.

The slim-fit design features a height-adjustable elastic waistband for a customized fit.

Nucleon PLASMA is a viscoelastic material made from bio-based polymers and molded to form a flexible structure in all directions, while maintaining its ability to dissipate impact energy. Lightweight and perfectly ventilated, these elbow and shoulder protectors provide excellent dispersion and absorption of impact force while ensuring maximum coverage in any riding position.
