  • Endura Pro SL Helmet, with Koroyd

    Crafted with the innovative Koroyd technology the Pro SL Helmet from Endura redefines the way we ride the road. Giving you the upper hand on your rivals, the impressive shock absorption and lightweight performance of this classically designed lid ensures that professional performance levels are simple to achieve.

    Just Breathe

    No matter how intense your cadence becomes the Pro SL Helmet, with Koroyd will always have your back. Utilising angled Koroyd tubes and large vents to optimise ventilation, the flow of air around your head is increased to help reduce sweat and odours. Keeping you focused as you look to break up the road, Endura’s antibacterial fast wicking spacer fabric padding works wonders to keep you fresh and comfortable from the first pedal until the last.

    Koroyd® Technology

    Tens of thousands of co-polymer extruded tubes, thermally welded to create an unparalleled consistent and fully engineered core, ready to be cut, shaped, cnc-ed, thermoformed or laminated and further integrated into the best sport and protection products that give you the edge. The cores plastically deform for higher speed impacts, absorbing energy linearly. Up to 84% of the material thickness can be utilised in case of an accident. Existing energy absorbers densify around 60%.
