Latest iteration of a classic helmet delivers on pretty much all fronts: styling, comfort and ventilation are all superb
Skip to view product specifications

The Prevail seems to have been around forever – it’s a familiar sight in races at all levels and has evolved, over time, into its current design. Its purposeful looks won’t appeal to everyone, but they clearly float the boat of many cyclists.

  • Highs: Venting, looks, fit
  • Lows: Some areas could be prone to damage during transit

It manages to look both chunky and supremely vented at the same time, with muscular shaping and aggressive vents. The rear extends low down for great head coverage, and the external shell protects the lower EPS core at the sides, but not front and rear, so a few parts that could be prone to damage in transit.

It has a satisfyingly cradling fit, which inspires confidence for long rides.

Specialized’s rear Mindset adjusting cradle offers five height positions, well placed pads and a rotary dial. Older Specialized helmets used to be quite narrow, but now accommodate rounder heads very well with no squeezing or pinching.

The straps are fixed by clasps at each side, but are ideally positioned to let the pliable chinstrap do its job. They exit from the middle of the shell, keeping them clear of the skin until the jawbone.


Deep internal channels align with the large frontal vents to rush cooling air across your cranium, and the horizontal brow vents do a fine job of managing sweat and drying the front pad. It’s very good for glasses storage when not wearing them too.
