Mountain Bike Helmet Buying Advice

Choosing the best mountain bike helmet is crucial to saving your life. Whether on the trail or racing, mountain bike helmets protect your head from getting hit and provide additional protection in case you fall off your bike. 

Here are some things to consider before buying a helmet: 

  • Protection

A mountain bike helmet’s most critical safety feature is the EPS liner, which gives it its strength and proper shape. An EPS liner can be found in nearly all mountain bike helmets on the market. 

Rigid polystyrene or polystyrene foam is often used for even more protection. An outer protective shell is another option for riders who want extra safety options.

  • Breathability

One of the essential safety features of a trail helmet is airflow to keep you cool during hot summer months or cold winter weather. A helmet with fewer vents for winter riding will usually keep the head warmer.

Most helmets have vents to improve airflow and can help a rider get through longer rides in hot weather without feeling too hot. 

  • Weight

A lightweight helmet is another crucial component for comfort and safety. The lightest helmets on the market weigh just over a pound and are available in mountain bike-specific models with high-tech materials that are both light and strong.

  • Interior Padding Materials

The fabric material is lightweight, breathable, and will dry quickly. It comes in a variety of colors and prints. It can be made with additional protective padding, which can be found in most helmets today.

  • Fit

A comfortable fit is also crucial for most riders. The helmet should not be too tight or loose for an ideal fit. Ensure the rear adjustment system is working correctly.

  • Convertibility

Many riders like to use their helmets for skateboarding, cycling, other activities, and mountain biking. You can buy a convertible helmet that can be converted from a bike helmet to one used for different sports.


What helmet is best for mountain biking?

The Giro Source is a popular choice among bikers because it offers the best combination of all-around protection and lightweight structure. It has an aerodynamic design that keeps you upright while upright and allows easy breathing and hearing. The helmet’s core, made of polycarbonate, is fitted with an EPS liner that offers more protection.

Is WaveCel technology better than MIPS?

Yes, WaveCel technology is better than MIPS. WaveCel technology absorbs more energy upon impact than MIPS, but it doesn’t cause the same amount of rotational force during or after. The WaveCel liner doesn’t shift within the helmet interior like MIPS, thus providing excellent internal stability and comfort.

Which cycling helmet is the safest?

Giro has been making helmets for over 35 years, and they better understand helmet safety than most companies. They base their research on real-life accidents and other studies, which means they can develop safer products.
