Downhill / Full Face Mountain Bike Helmets

If you’re riding downhill, you need the protection of a full face mountain bike helmet

Lift access riding demands a combination of bike handling skills, strength, and, let’s face it, plain old guts. A full face mountain bike helmet is essential for downhill, and sometimes a smart decision for dirt jumping or any gravity riding. Learn more about full face mountain bike helmets below. Want to know the difference between a $80 full face mountain bike helmet and a $300 helmet? Don't think you need all the protection of a full face helmet? Check out our full collection of mountain biking helmets, which are less restrictive, but still provide great protection for your head.

When do I need a full face mountain bike helmet?

Whether or not you need a full face mountain bike helmet depends on the kind of riding you’ll be doing. The risk of injury is inherent in mountain biking, especially in downhill mtb or any type of riding in which you’re going to be airborne (or trying to get air). Choose a mountain bike full face helmet if you plan on doing any riding with a high probability of crashing (even the best riders can and will crash). And choose full face mountain bike helmets if you like the styling, level of protection, or other features. Remember that helmets are mandatory in competitions; the sponsoring organization will stipulate in the rules if a full face downhill mountain bike helmet must be used.

What makes a full face mountain bike helmet different?

A mountain bike full face helmet differs from other bicycle helmets in a few distinctive ways.
  • First off is the obvious; your chin, jaw, and mouth are covered. This shields the lower half of your face from flying rocks, branches, and other debris and, more importantly, protects your face and jaw in the event of a crash or fall.
  • Full face downhill mountain bike helmets also typically cover more of the back of your head than other mountain biking helmets, which is helpful in the event of a backward fall.
  • Of necessity, full face mountain biking helmets are heavier than other bicycle helmets, although advances in materials technology has brought down their weight (and cost).
  • Regular mountain bike helmets typically have more venting than full face mountain bike helmets, which rely on passive as-you-go venting to circulate air through the helmet.
  • Full face mountain bike helmets have movable visors to help shield your eyes and the upper portion of your face.

XSportsProtective staff picks for full face mountain bike helmets

  • We like to newly updated Giro Cipher full face mountain bike helmet. The Cipher offers protection as well as upgraded features without an upgraded price tag. Some of the Giro Cipher full face mountain bike helmet features include:
    • Fiberglass exterior hardshell and EPS foam liner
    • Channeled ventilation at the brow line
    • Audio speaker pockets to accommodate Giro TuneUps audio drops. (TuneUps not included)
    • Integrated POV mount for a GoPro (camera not included)

    • No-tool, easy-adjust, bolt-on visor
  • We also like the Fox Rampage full face helmet, which is great for freestyle, downhill, or BMX. The Fox Rampage has a vented fiberglass shell over EPS hard foam and features soft cheek pads, synthetic suede lining, and a double D-ring chinstrap.
  • At a slightly lower price point, the SixSixOne Comp full face mountain bike helmet is tough to beat for the price. It offers equal parts comfort and protection for both novice and advanced bikers. The tough, poly-carbonate exterior shell features a full-view eye port designed to give maximum peripheral vision and allow any goggles to fit without interference.

Full Face Mountain Bike Helmet Comparison

If you’re in the market for a full-face mountain bike helmet, you’ve probably noticed there are a lot to choose from, with prices ranging from around $85 to over $400. That begs the question: What’s the difference between an $85 full-face helmet and, say, a $130 full face helmet? What more do you get from a $300 full-face helmet? We've taken some of our most popular full face helmets and compared them side-by-side in three different price ranges in order to make the choice a little easier for you.

When you’re deciding which helmet to buy, make sure you take into account all your needs. Yes, price and graphics are important, but is weight important to you? Are you looking for the safest helmet you can find? Do you need a helmet with great ventilation because you sweat a lot or live in a hot climate? Are you trying downhill for the first time or just starting to compete? Sure, your favorite mountain biker might wear a specific make or model, but this doesn't mean his helmet is the right one for you. Whatever full face helmet you choose, make sure it fits and make sure you wear it. Safe riding!
