The Mistral gives you a mid-tail aero design that is versatile across triathlon, track racing and time-trial efforts. Its smooth shell conceals six front openings and two rear openings, helping air move through the helmet while preserving its streamlined shape. Extended internal channeling supports the airflow path, while in-mould construction keeps the helmet suitably focused on race-day performance.
A clear magnetic polycarbonate visor attaches quickly and includes anti-fog treatment, giving you an integrated race setup without the fuss of conventional eyewear. Remove it when you want to use sunglasses or increase airflow. The included internal spare pad and insulating winter cap add useful flexibility between sessions.
Comfort comes from 3D Dry padding, a self-adjusting lateral divider and a faux-leather chinstrap that feels softer against the skin than a conventional fabric strap. The Mistral is certified to CE / UKCA - EN 1078, with the visor certified to CE / UKCA - EN 166. Independent testing found the fit comfortable and the helmet notably quiet at speed, but also highlighted limited ventilation during warmer or longer rides—an important consideration if you run hot.
A strong choice for triathletes, track riders and time-trial customers prioritising aerodynamic race performance, integrated eye protection and a comfortable fit over maximum hot-weather ventilation.
Mid-tail aero profile
The mid-length tail is designed to balance aerodynamic performance with versatility across triathlon and track-racing positions.
Concealed ventilation
Six front openings and two rear openings encourage airflow while keeping the outer profile smooth and streamlined.
Magnetic anti-fog visor
The clear polycarbonate visor attaches magnetically for quick race-day setup and provides integrated eye protection.
Comfort-focused fit
3D Dry padding, a self-adjusting lateral divider and an embracing lateral design help create a secure, comfortable fit.
Soft faux-leather chinstrap
The faux-leather strap offers a softer contact point under the chin than a traditional nylon strap.
Race-ready accessories
An internal spare pad and insulating winter cap are included, giving you practical options across different conditions.
Certified protection
The helmet meets CE / UKCA - EN 1078, while the visor meets CE / UKCA - EN 166.
