Alpinestars Nucleon Flex Proi Back Protector Insert

The extremely lightweight Level 2 CE and UKCA certified Nucleon Flex Proi Full Back Protector Insert features a highly ventilated hybrid of NucleonCell and Nucleon Flex protectors for the optimum balance of force dispersion and flexibility, with a soft-touch 3D mesh liner for enhanced rider comfort.The back protector insert is a full-length back protector, about 22% longer than regular back protector inserts. The Nucleon Flex Proi is compatiblewith all Alpinestars' sport and touring jackets that have released since Spring 2022, as all jackets have a double pocket to insert either a regular orlonger 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.
