Alpinestars Nucleon KR-CELLi Back Protector

Experience revolutionary spine protection engineered for performance riders seeking uncompromising safety and comfort. This CE-certified marvel redefines lightweight armor through its pioneering KR-CELLi microstructure – absorbing high-impact forces while maintaining exceptional airflow during aggressive sport riding or summer touring.

– Triple-Articulated Polymer Shell flexes naturally with your spine movements while shedding weight – critical for endurance rides
– Intelligent Impact Diffusion through graduated cell density disperses collision energy outward from vital vertebrae
– Dynamic Ventilation System channels heat away via thousands of micro-aircells beneath breathable airmesh lining
– Ergonomic Contouring mirrors spinal curvature while horizontal flex grooves adapt to racing tucks or relaxed cruising
