The Kask Protone road cycling helmet offers next level aero performance. Designed for road racing the Protone has been wind tunnel tested to reduce air turbulence. The large vents keep you cool but are also positioned with effective exhuasts to ensure optimum through flow of air.
Kask's Octo Fit micro dial adjuster cradles further down your head and neck than many other manufacturers on the market. The helmet feels less perched on your head.
Advanced in-mould construction joins the inner cap to the outer which improves shock absorption.
Kask are the choice for Team Sky so you can be sure the Kask Protone will improve your performance, comfort and look when you're in the saddle.
The tridimensional 3D DRY padding utilizes a multi-layer open cell construction process: high technology for the best comfort and performance.
Incredibly aerodynamic and top performing shell, tested in the wind-tunnel and able to provide a really impressive CX rate. Any position the head will assume the outflow of the air will be perfectly in line with the helmet.
Removable and washable inner padding in Coolmax® material
In case of shock it avoids the break of the helmet into pieces
M in moulding
The innovative “in moulding” technology, joining the inner polystyrene cap to the outer polycarbonate one, ensures a better shock absorption.
The MIT Technology, applied to all KASK cycling helmets, guarantees a higher safety and a complete protection thanks to the polycarbonate layer that covers the shell on the top, on the base ring and on the back.
Inner padding fabric treated with antibacterial and antimicrobial Sanitized® process.
High visibility stickers for maximum safety even in poor visibility conditions
