Gear up with the best full face MTB helmets built for downhill, enduro, and freeride—with top protection and innovative features.

Mountain biking is one of the most thrilling and demanding outdoor sports. Whether you’re tearing down a downhill trail, navigating rocky terrain, or hitting a dirt jump, one thing remains non-negotiable: safety. And when it comes to head protection, full face mountain bike helmets are the gold standard—especially for aggressive trail riders, enduro racers, and downhill enthusiasts.

But not all full face helmets are created equal. Choosing the right one can be the difference between a safe ride and a dangerous mishap. In this detailed guide, we’ll explore what makes a full face helmet great, what features to prioritize, and how to find the best fit for your riding style and budget.

What is a Full Face Mountain Bike Helmet?

A full face helmet is designed to provide maximum protection by covering the head, face, chin, and jaw—unlike half-shell helmets that only protect the top and back of your head. It resembles a motocross helmet and includes a chin bar, often with a visor, providing enhanced safety during high-speed descents and technical trails.

Why Choose a Full Face Helmet?

The decision to wear a full face helmet often comes down to riding style and risk level. These helmets are particularly recommended for:

• Downhill (DH) biking

• Enduro races

• Bike park sessions

• Freeride and dirt jumping

If you’re riding trails where the risk of falls, crashes, or impacts is higher, a full face helmet is a wise investment.

Key Factors to Consider When Choosing a Full Face Helmet

1. Safety Certifications

The first and most critical factor is whether the helmet meets recognized safety standards. Look for:

• ASTM F1952: The standard for downhill mountain biking helmets.

• CPSC: U.S. Consumer Product Safety Commission for bike helmets.

• EN 1078: European standard for cycling helmets.

The presence of certifications ensures that the helmet has been tested for impact resistance, retention system strength, and other safety features.

2. Fit and Comfort

A poorly fitting helmet can compromise protection and cause discomfort. Here’s what to look for:

• Size Options: Measure your head circumference (usually above the eyebrows) and refer to the manufacturer’s size chart.

• Padding: Look for helmets with removable, washable, and moisture-wicking padding. It should snugly hug your head without pressure points.

• Retention System: A dial-fit or adjustable strap system ensures the helmet stays secure during intense rides.

Tip: Try the helmet on before buying if possible. Shake your head side to side and up and down; the helmet should remain stable.

3. Ventilation

Full face helmets are naturally warmer than half-shells, but modern designs offer excellent airflow through strategically placed vents and channels. Look for:

• Multiple large vents for both intake and exhaust.

• Breathable liner materials.

• Open-face hybrid options for better breathability during long climbs.

For enduro riders who have to pedal uphill before descending, ventilation becomes even more crucial.

4. Weight

Weight is an essential consideration—especially if you’re pedaling for hours. Heavier helmets provide great protection but can cause fatigue over time.

• Carbon fiber and composite shells are lighter but more expensive.

• Polycarbonate helmets are affordable but generally heavier.

Look for helmets under 1000 grams if you want a balance between safety and comfort.

5. MIPS and Advanced Protection

Modern full face helmets often feature MIPS (Multi-directional Impact Protection System) or similar technologies to reduce rotational forces during a crash. This is especially valuable in protecting against concussions.

Some helmets may also include dual-density EPS foam or smart shock systems that absorb and disperse energy more effectively.

6. Removable Chin Bar

If you’re an all-mountain or enduro rider, a helmet with a removable chin bar offers two-in-one versatility. Use it in full face mode for descents and switch to open-face for climbs or casual rides.

Brands like Bell Super DH or Giro Switchblade are known for their quality convertible helmets.

7. Visor Design

A good visor does more than just block the sun:

• It should be adjustable to accommodate goggles.

• Some are breakaway to reduce injury risk during crashes.

• Certain visors are designed to work with action cameras like GoPros.

Additional Considerations

Goggle Compatibility

Most full face helmets are designed to pair with goggles rather than sunglasses. Make sure the eye port accommodates your preferred goggles, and that the helmet has a goggle strap holder.

Style and Aesthetics

While safety is the priority, you’ll also want a helmet that reflects your personality. Full face helmets come in a wide variety of colors, designs, and finishes.

Price Range

Expect to pay anywhere from $100 to $600+ for a full face helmet:

• Budget: Basic protection, heavier, fewer features.

• Mid-range: MIPS, decent ventilation, solid comfort.

• High-end: Lightweight materials, superior padding, advanced safety tech.

Top Brands to Consider

When shopping for a full face mountain bike helmet, you can’t go wrong with these trusted brands:

• Fox Racing (e.g., Proframe)

• Troy Lee Designs (e.g., Stage, D4)

• Bell (e.g., Super DH, Full-9)

• Giro (e.g., Switchblade, Insurgent)

• POC (e.g., Otocon)

• Leatt (e.g., DBX 4.0)

Final Thoughts

Choosing the right full face mountain bike helmet boils down to your riding style, terrain, and personal preferences. Whether you prioritize lightweight comfort, maximum protection, or versatile convertibility, there’s a helmet that matches your needs.

Before purchasing, always:

• Check reviews from real riders.

• Try it on for fit and comfort.

• Don’t compromise on safety features—especially certifications and impact protection.

Remember, your helmet is the most important piece of gear you’ll wear on a ride. A quality full face helmet isn’t just a product—it’s a life-saving investment. Ride hard. Ride safe. Protect your head.
