A strong choice for riders wanting a comfortable, ventilated and understated helmet for fast road rides, all-day adventures and mixed-surface riding.
The Protone Icon WG11 is designed for riders who want one helmet that works across road rides, gravel, cyclocross and MTB cross-country. At 230 g, it keeps weight low without chasing a single performance metric at the expense of everyday comfort. The vented shell and internal channels help move air across the head, while the rounded profile provides a practical balance of ventilation and aerodynamic efficiency.
Fit is handled by OCTOFIT+, combining a grippy rubber adjustment dial with a vertical stabiliser and ergonomic neck support. It is straightforward to fine-tune on your head, although you may need to reset the height adjustment when putting it on. The CoolMax lining is removable and washable, and the soft faux-leather chinstrap is comfortable against the skin and easy to clean.
Inside, a redesigned strengthening frame helps maintain the helmet’s compactness in an impact. Kask’s WG11 rotational-impact test evaluates performance against rotational forces beyond standard impact testing, while the CE / UKCA EN 1078 certification confirms the applicable helmet standard. A rear reflective insert adds a useful visibility detail for commuting and lower-light rides. Choose size M for a 52–58 cm head circumference.
