The Alpinestars Nucleon KR-Cell Back Protector in Medium is designed to provide protective coverage, flexibility, ventilation, and comfort for riders. Its back hard-shell plates are constructed from a high-performance polymeric material blend that supports weight-saving properties while allowing the protector to flex with the rider.
The highly perforated shells promote airflow, while the single-injected compound shell uses a triple-layer design to absorb impacts and maintain ventilation. An ergonomic protector plate follows the natural curve of the back for an adaptive fit in the riding position, and horizontal flexion grooves further support freedom of movement.
Adjustable, detachable elastic shoulder straps use a snap-fit system for a comfortable fit. The kidney belt features a dual hook-and-loop closure system, while the soft bio-foam padded chassis adds comfort during use. This protector is compatible with the Nucleon KR-C protector.
