MTB helmets

Whether you're heading out for a leisurely ride or tackling a challenging downhill session, wearing a mountain bike helmet is essential. More than just a piece of equipment, it's your first line of defence against the unpredictable nature of the trails. Explore our range of MTB helmets designed to combine safety, comfort, and ventilation, from demanding cross-country to the most technical descents.

Why choose a mountain bike helmet suited to your riding?

Trail conditions are constantly changing: slippery roots after rain, loose rocks on descents, low branches in the woods. The right MTB helmet does more than absorb impacts-it stays secure on your head and effectively manages heat during long climbs. This balance of protection, ventilation, and comfort is what separates a helmet you forget you're wearing from one that becomes a distraction.

Key safety and comfort features

For true functionality, a mountain bike helmet must combine two factors: protection and ventilation. First, ensure your helmet is certified to European standard EN 1078, guaranteeing impact absorption that meets cycling requirements. Depending on the model and your intended use, weight can also be important. The shape can influence comfort as well. Several elements deserve special attention when making your choice:

• EN 1078 certification, essential for safe mountain biking.
• Retention system, usually adjusted by a dial at the back for a precise fit.
• Inner padding, ideally removable and washable to maintain comfort over time.
• Chin strap, adjustable and equipped with a secure buckle, often magnetic on recent models.

The different types of MTB helmets

Each mountain biking discipline has its own requirements, and manufacturers have responded accordingly. Full-face helmets, featuring a chin guard that wraps around the face, are designed for downhill and demanding enduro riding, where impacts can be particularly severe. Some models offer a removable chin guard, allowing you to switch from full-face for descents to open-face for climbs, providing welcome versatility for enduro. Lighter and more ventilated, open-face helmets are ideal for cross-country and trail riding, with extra coverage at the back of the head and over the temples. There's also a dedicated kids and junior range, with adjusted sizing and simplified adjustment systems, available in our kids' MTB helmets section.

How to choose the right MTB helmet?

Having an ergonomic helmet suited to your head shape and riding style ensures your experience isn't compromised. A helmet that restricts your vision or isn't comfortable can quickly become a problem. To help you decide, we've gathered in our selection of the best MTB helmets our detailed reviews of the season's must-have models. Our men's MTB helmets and women's MTB helmets sections also let you refine your search by fit.

Considering size and fit

Determine your size by measuring your head circumference with a tape measure, about 2 cm above the eyebrows at the widest part of your head. Each brand publishes its own size guide, so it's essential to check before ordering, as a size S from one brand may be an M from another. A properly fitted helmet sits flat on your head, doesn't drop over your eyebrows, and stays in place when you shake your head-even with the chin strap undone. If the helmet tilts forward or backward, the fit isn't right for your shape.

The importance of ventilation and weight

Ventilation becomes crucial as temperatures rise or climbs get longer. Well-placed vents aligned with airflow help wick away sweat and prevent overheating on ascents. Weight is equally important for comfort: expect 250 to 350 grams for an XC helmet, 350 to 500 grams for an open enduro model, and sometimes over 900 grams for a full-face downhill helmet. The goal is to find the right balance between protection and lightness, depending on your riding and terrain.

Innovative technologies in MTB helmets

Manufacturers are constantly innovating to push the boundaries of safety without sacrificing comfort. In recent years, advances in impact absorption and lighter structures have transformed the range, even in entry and mid-level models.

MIPS technology for enhanced protection

How can you reduce the risk of injury from an angled impact, which is much more common than a direct frontal hit? The MIPS system (Multi-directional Impact Protection System) addresses this with a thin yellow inner layer that allows slight movement between the shell and your head during impact. This movement of a few millimetres absorbs some of the rotational forces responsible for many concussions. Widely available from brands like POC, Scott, and Smith, MIPS is now considered a standard for riders prioritising safety.

Advanced materials for lighter weight

Most current models use high-density polycarbonate shells combined with multi-density EPS foam. Smith stands out with its honeycomb Koroyd structure, featured in several high-end models: these heat-welded polymer cells improve impact absorption while enhancing airflow, resulting in helmets that are both more protective and better ventilated. The result: helmets that are more comfortable on long rides and often more stable on the head thanks to better weight distribution.

MTB helmet FAQ

What is the lifespan of a mountain bike helmet?

The average lifespan of a mountain bike helmet is 3 to 5 years with normal use, even without any impacts. EPS foam and shell materials naturally degrade due to UV exposure, sweat, and temperature changes. After a significant impact, even if there's no visible crack, replacement is essential: the foam may have compressed internally and lost some of its shock-absorbing properties, compromising protection in the event of another impact.

How do you care for your MTB helmet?

To keep your helmet in good condition, clean the outer shell with a damp cloth and mild soap, avoiding any harsh products or solvents that could weaken the materials. Removable inner pads should be hand-washed in lukewarm water and air-dried out of direct sunlight. Store your helmet in a dry, temperate place, away from heat sources like a car boot in summer, which can irreversibly damage the foam.

Can you use a mountain bike helmet for other mountain sports?

Each discipline has its own certification standard and protection requirements. An MTB helmet meets EN 1078, while climbing requires EN 12492 and skiing EN 1077. Protection zones and impact tests differ, so it's best to use each helmet for its intended purpose. For high-speed e-MTB (over 25 km/h), the reinforced NTA 8776 standard is recommended.

What accessories are compatible with MTB helmets?

Most modern MTB helmets are designed to accommodate various useful accessories:

• Action cameras like GoPro, attached with adhesive or clip mounts on the top or chin guard.
• Front and rear lights for safer rides at dusk or in shaded woods.
• Removable visors with adjustable height, to shield from low sun or mud splashes.
• MTB goggles and sunglasses shaped to fit the front of the helmet without blocking ventilation.
