Fox: The Ultimate in Head Protection. Born from dirt. Fueled by Passion. Fox continues to push the boundaries with stylish, innovative, and effective headwear for mountain bikers. And trust us—it’s needed.
Adrenaline junkies worldwide turn to this California company to ensure that a day they spent cutting the trail and feeling the thrill of launching from a jump isn’t their last. It’s impossible to go wrong with one, but with so many options, how can you choose?
Thinking of skimping on your mountain bike helmet to save a few bucks? Don’t.
Sure, massive Big Bore vents, advanced ratchet retention systems, sturdy EPS foam, and futuristic moisture retention systems that would make the entire agricultural industry green with envy have driven the price up a tad, but it’s worth it.
We’ve scoured the Amazon marketplace for Fox’s top models. We considered dozens, and only a few have lived to tell the tale. We’ve taken comfort, protection, price, and style into account (it’s hard to look bad mountain biking, but looking great never hurts). We focused solely on standard helmets. If you want full face, you’re out of luck.
What makes a good mountain bike helmet, anyway? All of that crazy, borderline-death-defying action (slight exaggeration!) does come with risks, but protection is just a part of the equation. We’ve also considered comfort and fit. Our criteria were:
Protection: Nothing is as important as the foam liner that sits between your heads and the ground.
Fit: Your ride is only as enjoyable as your lid. Foam padding, adjustable heights, Y-strap systems—you name it, we considered it.
Ventilation: Finding the right balance between keeping your head cool and keeping it safe is a delicate task. These models are the “coolest”. Literally.
Convenience: Protection and fit are foremost, but a little extra convenience never hurt either.
Without further adieu, we present the best Fox mountain bike helmets on Amazon:
