Aesthetically, the Protone reflects the two schools of thought which make up the finished product. One half of the helmet features the smooth, punctured surface of your typical time trial helmet, whilst the other half conforms to a more ‘standard’ design with vents to encourage effective airflow. This ultimately gives riders the best of both worlds, with an aerodynamic form to aggressively mitigate drag; whilst also remaining as a helmet that you wouldn’t mind wearing for hours on end. The Kask Protone helmets have also been historically favoured by Team Sky, with the likes of Bradley Wiggins and Richie Porte sporting Kask’s flagship helmets. You can find even more from the brilliant Kask team at Westbrook, including both the Kask Mojito & Kask Bambino Pro.
