Alpinestars Nucleon Kr-Cell Cir Protector Transparent Smoke Red 003

The Alpinestars Nucleon KR-Cell CiR chest protector is designed for sport and track riders who demand high-level protection combined with exceptional comfort and ventilation. This ultra-lightweight chest protector is built for high-performance riding.

Featuring advanced Nucleon Cell technology, the CiR delivers outstanding impact energy absorption while maintaining excellent flexibility, allowing the protector to move naturally with the rider.

The dual-layer chest plate is constructed from a premium polymer blend that optimizes flexibility while keeping overall weight to a minimum, ensuring stability without restricting movement.

A unique CELL microstructure maximizes airflow through the protector, promoting efficient heat dissipation and maintaining comfort during intense riding sessions or extended track use.

On the body-facing side, a soft and breathable airmesh lining enhances rider comfort and reduces pressure points when worn directly against the body or under a race suit.

The ergonomic shape follows the natural contours of the chest and upper torso, ensuring a secure fit and consistent protection across all riding positions.
