Alpinestars Nucleon KR-R Cell Back Protect Transparent Smoke Red Black

The Alpinestars Nucleon KR-R hybrid back protector is a Level 2 CE-certified, innovative track and race back protector. The new Cell Technology back protector is constructed from a high-performance polymeric material blend for optimised flexibility and excellent weight-saving properties. Developed in three waist-to-shoulder dimensions to cover all body sizes, it is highly perforated for maximum breathability and ventilation. The ergonomically designed protector contours to the natural curve of the back, ensuring an optimal fit while riding, with horizontal flexion grooves for an adaptive fit in various riding positions. The extended lower back protector offers more protection to the rider and is compatible with the Nucleon KR-TB protector for extended lower spine protection. A height-adjustable kidney belt features a dual hook-and-loop closure system, providing easy and secure closure. The soft Bio-Foam padded chassis offers maximum comfort.
