Alpinestars Nucleon Kr-Cell Cis Protector Transparent Smoke Red 003

The Alpinestars Nucleon KR-Cell CiS chest protector is engineered for high-performance track and sport riding, offering exceptional protection in an ultra-lightweight and low-profile design. It delivers maximum safety without compromising rider comfort or freedom of movement.

Utilizing advanced Nucleon Cell technology, the CiS efficiently absorbs impact energy while remaining flexible, allowing the protector to move naturally with the rider during aggressive riding conditions.

The innovative open-cell microstructure promotes continuous airflow throughout the protector, ensuring excellent ventilation and effective heat dissipation during demanding riding sessions.

The dual-layer chest plate is constructed from a premium polymer blend that provides an ideal balance of flexibility, impact protection and significant weight reduction, making the protector barely noticeable under a race suit.

On the body-facing side, a soft and breathable airmesh lining enhances comfort and reduces pressure points, even when worn in tight-fitting performance gear.

The ergonomic shape closely follows the natural contours of the torso, keeping the Nucleon KR-Cell CiS securely in place and delivering consistent protection in all riding positions.
