Introducing the Nucleon KR-Cell Back Protector, designed with three waist-to-shoulder dimensions to accommodate all body sizes. This back protector features hard shell plates made from a high-performance polymeric material blend, ensuring optimized flexibility while being lightweight.
The shells are highly perforated for maximum breathability and air ventilation, enhancing comfort during rides. The single injected compound shell utilizes a triple-layer design to absorb impacts effectively while allowing for maximum airflow.
Its ergonomic protector plate contours to the natural curve of the back, providing an optimal fit in the riding position. Additionally, horizontal flexion grooves are incorporated for an adaptive fit.
Equipped with adjustable, detachable elastic shoulder straps featuring a snap-fit system, it ensures a comfortable and secure fit. Furthermore, it is compatible with the Nucleon KR-C protector and includes a kidney belt with a dual hook-and-loop closure system. For added comfort, the soft bio-foam padded chassis ensures maximum comfort for the rider.
