Kask Protone Road Bike Helmet

The Kask Protone helmet is an incredibly lightweight road bike helmet, weighing only 215g. The vents have been carefully designed to provide the fastest heat dissipation while still having one of the lowest drag coefficients of any ventilated road cycling helmet.

Kask have used removable and washable 3D Dry padding that has a multi-layer open cell construction that is exceptionally comfortable. Made from CoolMax® fabric and treated using the Sanitized® antimicrobial process. Perforations in the padding increase wicking speed to keep your brow dry on long summer rides.

The Protone Road Helmet uses its Multi In-Moulding Technology to create a polycarbonate cover for the top, base ring and the back of the helmet’s shell. This is joined to the inner polystyrene cap via KASK’s In-Moulding Technology to improve the shell’s shock absorption. Its strengthened frame further reduces the risk of a shock breaking the shell.
