Before buying the first helmet you see, consider a few things about your biking style and head.

Falls are a part of mountain biking

Accidents and falls are a part of mountain biking. You can never perfect the skills of mountain biking without having a few close calls and dangerous falls. When you are trying to push your limits and taking risks, always wear a helmet!

Most falls are usually not a big deal, but sometimes you hit the ground hard and fast, and for those times, you will need a helmet protecting your head against any damage that can be caused.

Things to consider before buying your helmet

What is your Riding Style?

There are different types of helmets for different riding styles. Think about whether you are going to be riding cross country trails or are riding aggressive trails downhill?

Cross-country or XC riding would require a lighter and more ventilated helmet, while if you are racing downhill, you would need a helmet that has better coverage on all sides of your head or maybe a full-face helmet.

The Climate you will be riding in?

Think about the kinds of weather you usually ride in. If you are cycling in hot or humid conditions, ventilation is a significant factor. If you are riding in the cold, maybe you would want a helmet with an insulated liner.

Riding in the cold would also not require as much ventilation in your helmet. Visors are also crucial if you want to protect your eyes from dirt, water, and even the sun.

Comfort and fit

You want a helmet that fits! Consider the size of your head and its shape before buying a helmet.

A poorly fitting helmet will not only be uncomfortable, but it will also be less safe than a properly fitting one.

Safety should be your number one priority. Make sure whatever helmet you buy is of good quality and is certified to maintain standards in your country.

The Consumer Product Safety Commission for the United States of America or the General Product Safety Regulations in Europe are some of the certifications you should look for.

Also, there are lots of additional safety features in most helmets on the market like MIPS, WaveCel, or Koroyd that provide different kinds of protection against straight or rotational forces that might happen in accidents on your mountain biking adventures.

Types of helmets

Cross-Country or XC helmets

XC helmets are close to regular road biking helmets. They are made to be lightweight and well ventilated for long and winding rides.

If you want to cover lots of ground and aren’t riding on too technical or dangerous trails, these helmets are a good choice.

Trail Helmets

Trail helmets are for cyclists riding down more technical and sketchy trails than your typical cross country rides.

These helmets have a lot more protection on the sides and back of your head but are still very well ventilated, so you don’t get too hot and sweaty in your longer rides.

Downhill Helmets

These helmets are for those who are going downhill aggressively and fast. These helmets offer your head complete protection from all sides and angles, but at the cost of ventilation.

There are even full-face helmets for your downhill mountain biking needs. These helmets aren’t recommended for rides that require lots of pedalling over long periods as they will turn your head into a hot and sweaty mess.
