What Should You Look for When Buying a Helmet?

As you look through the helmets, there are a couple of details you should keep in mind as you search so you can decide on the absolute best mountain bike helmet for you.

  • MIPS Technology – For those of you not familiar with MIPS Technology, it stands for Multi-directional Impact Protection System. Basically, MIPS gives your head an extra layer of protection in the event of a crash.

It gives helmets a low-friction layer that lets the helmet’s liner rotate very slightly around your head during a crash. It hardly moves at all, but it does lessen the amount of rotational force that could be transferred to your brain during certain types of bike crashes.

  • Special Features – Every helmet offers some protection to your head, but they offer it to you in different ways. There are different types of features on helmets that can make you absolutely love them, or avoid wearing them at all cost. We go more in depth in different features of helmets below.
  • Shock Proof – Helmets categorized as “shock proof” provide your head with an extra layer of protection to absorb the shock of the impact when you hit the ground. It can be the difference between a lesser injury and a much greater head injury.
  • Size – Be sure to pay attention to the size of your helmet! You need one that is tight enough actually protect you in the case of an accident, but it shouldn’t be annoyingly tight. It should sit straight on your head without being tilted back.

The front section should be an inch or less above your eyebrows to protect your forehead. Once you get one, fasten it on and try pushing it side to side and back to front. If it shifts an inch or more, it needs to be adjusted.

Understanding Special Features

Rather than just buying the first helmet that looks good, you may want to read further into whatever special features it has. Some people find they have a much stronger opinion than they thought about some features! Read on down the list to decide what you do and don’t want in your new helmet.

  • Visor – One very common type of special feature on a helmet is a visor. Visors are the part of the helmet that reaches out to shade your eyes a bit from the sun. These are helpful on really sunny (or even rainy) days, but it should be noted that they add a tiny bit more weight as well as a bit more wind resistance.
  • Ventilation – The more vents are in a helmet the cooler the wearer will be. The more vents there are also cuts back a bit on the weight of the helmet. Of course, if it rains, the more vents there are the wetter your head will get.
  • Full-Face Protection – For those planning on doing a lot of biking downhill, helmets with full-face protection can be a worthwhile investment. These have a wraparound chin bar to help keep you from getting as injured if you fall off your bike.
  • Hair Port – Some helmets design their straps to allow for a ponytail to easily fit through the back. If you plan to wear a ponytail while biking, a hair port would add to your comfort and ease while biking.

More effort goes into making a helmet than you might first realize! It’s awesome that you can get a helmet so specifically suited to your needs.

We couldn’t decide on our absolute favorite out of our top twelve, but there were five in particular that really caught our attention. We’ve highlighted some of their features in the section below.

3. Bell Super 2R MIPS Equipped Bike Helmet

This third choice is a good one for those of you who plan on biking particularly rough trails. It’s made to keep you safe even in the more dangerous accidents. It is equipped with MIPS technology to help give your brain as much protection as possible. It also has a removable chin bar.

The helmet also has a sun visor and 23 air vents to make you as comfortable and cool as possible, even on hot sunny days.

One last helpful aspect of the helmet that shouldn’t be left unsaid is that it has a TAG fit system. This fitting system allows you to adjust the helmet in several different places to have the best fit possible. The benefits of this are twofold. It gives you added comfort a well as extra protection.

4. Bell Super 2 Helmet

This helmet is an eye-catching one! It comes in over ten bright colors to choose from.

Although the helmet is not equipped with the MIPS technology and isn’t defined as shockproof, it does give your head excellent padding and protection for normal mountain rides. If you plan on riding particularly rough terrain, though, it may be in your best interest to consider a helmet with a bit more extra protection.

The helmets are sized a bit small, so you will most likely fit in the helmet that is one size larger than your regular size.
