Trail legacy.

When Fox Racing first introduced the Flux Helmet, it was one of the few trail-specific helmets available. This year — its 10th birthday — the Flux is joined by plenty of formidable competition, but it still holds its own as a lightweight, affordable player in the trail market. The 2016 version now boasts an all-new dial-actuated retention system for an even more customizable fit.

Probably the most notable feature of the Flux is its extensive rear coverage, providing valuable protection to the vulnerable areas on the back and sides of the head. The Flux's lightweight EPS foam protection stays the same from past years, with Fox adding 17 strategically-shaped vents to usher air in and out of the helmet to keep you cool-headed on the trails.

My helmet of choice for the last 5 years

  • Familiarity: I've put it through the wringer

I've been wearing Flux helmets on trails for a few years now, and have had no reason to change. Comfortable, lightweight and plenty of ventilation. Humidity is a killer where I live, so this helmet is perfect.

  • Familiarity: I've put it through the wringer

I have ridden with the Fox Flux for a solid five years. Luckily I have only gone through two helmets in that time. The 17 vents offer ample ventilation for riding in the desert or those hot summer days in the mountains. The visor is a little flimsy compared to other helmets but it is easily replaced if broken. I am interested to see how the new dial fit retention system compares to the old Detox system (I will report back on this later). I would highly recommend this to any mountain biker looking for a reasonably priced, lightweight helmet that can do it all.

Feel free to shoot me any questions about the Flux or any other bike helmets.
