Nucleon KR-Cell Back Protector

A light and flexible Alpinestars back protector that fits under an outer garment, with an ergonomic protector plate that follows the contour of the rider's back.

Protection

• The back hard shell plates are constructed from a high-performance polymeric material blend for optimized flexibility and weight-saving properties.
• A single injected compound shell with a triple-layer design absorbs impacts and allows airflow.
• The shells are highly perforated for breathability and air ventilation.

Fit

• Developed in three waist-to-shoulder dimensions to cover all body size types.
• The protector plate contours to the natural curve of the back for an optimal fit in the riding position.
• Horizontal flexion grooves for an adaptive fit.
• Adjustable, detachable elastic shoulder straps with a snap-fit system.
• The kidney belt has a dual hook-and-loop closure system, and the chassis is soft bio-foam padded for comfort.
• Compatible with the Nucleon KR-C protector.
