The Jetpilot Hyperflex vest is built to provide the ultimate riding experience in a jacket. Using a hyperflex panel around the stomach of the jacket, allows unhindered movement and flexibility unique to this model. This is then combined with Jetpilot's signature flex-lite neoprene and high end freelite foam, keeping the Hyperflex vest lightweight while maintaining that neoprene stretch. Finishing with an anatomical fit and beveled buoyancy foam means that the jacket will conform to fit with ease and comfort.All of Jetpilots PFD have been rigorously tested and are certified to Australian Standards AS4758.This will give you peace of mind when you are participating in your chosen water sports activity.
