Alpinestars Nucleon KR-Celli Back Protector Insert: Want CE armour but don't want to feel it?

The construction of Alpinestars Nucleon KR-Celli Back Protector Insert allows maximum airflow to ensure that you stay cool. It's extremely lightweight and flexible motorbike protection that you won't feel while riding. The CE Certified armour insert has a different structure down the spine and on the outer edges, meaning it balances force dispersion and energy absorption better than most armour.
