Ideal for riders wanting one comfortable, lightweight helmet for road training, racing, gravel and everyday all-season use.
The Kask Protone Icon is a versatile helmet for road, gravel, cyclocross and cross-country MTB riding. Its design balances ventilation with aerodynamic efficiency rather than chasing only one performance metric, making it a practical all-rounder for everything from hot climbs to cooler all-season rides. The internal channels help move air through the shell, while the 230 g construction keeps the helmet pleasantly light on your head.
Fit is central to the Protone Icon’s day-to-day appeal. The OCTOFIT+ adjustment system combines a grippy rubber dial with a vertical rear stabiliser and ergonomic neck support, giving you a secure, customised fit that is easy to fine-tune. The removable, washable CoolMax® lining helps manage moisture, and the soft faux-leather chinstrap is easy to clean and designed for comfortable contact with the skin.
The Protone Icon also brings thoughtful details for regular riders, including a reflective rear insert for added visibility and front vents that can securely hold sunglasses. Its internal strengthening frame is designed to improve mechanical strength and help prevent the helmet breaking into many pieces during an impact. Kask’s WG11 rotational-impact protocol adds dedicated rotational-impact testing alongside CE / UKCA EN 1078 compliance. Choose it if you want a polished, comfortable helmet that performs consistently across road and dirt without feeling overly specialised.
