Alpinestars Nucleon Flex Proi Motorcycle Back Protector – Smoke/Black

The Alpinestars Nucleon Flex Proi motorcycle back protector is an extremely lightweight CE Level 2 & UKCA certified jacket protector insert that keeps you safe. The Alpinestars motorbike back protector features a highly ventilated hybrid of Nucleon Cell and Nucleon Flex protectors for the optimum balance of force dispersion and flexibility. A soft-touch 3D mesh liner delivers enhanced rider comfort.

The motorbike back protector insert is a full-length motorcycle back protector, about 22% longer than regular back protector inserts. The Nucleon Flex Proi is compatible with all Alpinestars sport and touring jackets that have released since Spring 2022, as all jackets have a double pocket to insert either a regular or longer back protector insert. The goal of the Nucleon Flex Proi is to deliver full-length coverage in terms of protection, like a fixed back protector does,but with the practicality of an insert. Please contact us if you’re unsure of compatibility.
