Item # FXR2580


The more you ride, the more you find yourself hanging out in mid-air. This is a good thing, but as your riding progresses, crashes become more dangerous because you're riding faster over steeper, more technical terrain. You need better protection, and the folks at Fox would like to give it to you. The Fox Women's Flux is designed for all-mountain riders who are doing more than rolling slowly down a smooth trail.

The Flux helmet is cut low in the back for added protection. This is extremely important for all-mountain riders, who generally ride more technical terrain than XC riders. the Flux offers about as much protection as you can get, short of buying a full-face helmet, and those tend to be pretty hot during the climb.

The Flux is a single-impact helmet, which means it does a better job of protecting your skull during a crash than a multiple impact helmet, but needs to be replaced after that first big impact because the EPS foam becomes deformed. The visor helps keep the sun and branches out of your eyes. It can also be removed. Fox's Detox retention system allows you to dial in the fit, so you can wear it however you find to be most comfortable.

Fox punches 20 large vent holes in the shell, so you'll get plenty of airflow on hot days. The vents are designed to force air into the helmet so it flows around and cools your head. An adjustable chin strap keeps everything snug while you ride.

The Fox Women's Flux Helmet is available in three sizes -- X-Small/Small, Small/Medium, and Large/X-Large. It comes in Black or White/Grey/Pink. It passes the following test standards for safety: CPSC, CE: EN1078, and AS/NZS 2063.

same lid, different paintjob

spent a minute closely inspecting if there's actually a difference between the unisex/men's Flux helmet (which I loved and wore all spring/summer/fall) and the women's version - and nope! They're the exact same down to the rear spoiler. So ladies (or gentelmen who don't care about gender assignments) - save yourself an extra 20 bucks while it's on sale and pick this up!

Any helmet that can tolerate direct impacts at high speeds wins in my book, but the Flux is so much more than that: sturdy, affordable, quality materials put together in one really attractive package.

From the coloring to the impact-resistance and venting qualities, this helmet registered further up on the scale with a few of the more-expensive helmets on the market, but definitely took a points hit for sizing accuracy; I ordered a M/L as I generally wear a Medium in my TLD D3 downhill full face, but the M/L Flux is too big even on the tightest setting.

If you're looking for a great summer trail helmet, however, this is the way to go: the vents are wide and generous, but the shell is deep enough that it doesn't register as 'flimsy' in the slightest.

The Flux is great as a travel-bike helmet as it straps easily to my carry-on pack and doesn't scuff or dent easily while being shuffled around an overhead bin. It's also very convenient for POV camera placement, bike light mounting and sunglass-use. All of the above fits nice and flush and doesn't seem to affect the radness of said helmet.

Overall, a really great quality helmet that I'd definitely purchase again, albeit in a different size.
