Best convertible full-face MTB helmet with removable chin bar

Full face mountain bike helmet with removable chin bar

We all know that a helmet is an essential equipment a bike rider should have. Now we have mainly two types of helmets, a full face MTB helmet, and an open face MTB helmet.

Some bikers choose a full face for better protection, as the open face helmet does not protect your face. But it is a good option for cross country riding and for climbing as these open face helmets are lightweight and cool.

However, if you are proceeding towards upraised biking experience, including severe descents, you should go for a full-face helmet, as these helmets are great for speedy and risky descents.

Full face helmets have better shock absorption, complex structure, and improved internal padding. The chin bar gives you 360-degree protection and confidence. But historically, the main issues riders had with these helmets were that these were heavy and less ventilated. Now, as the techniques of riding evolved, these helmets are also developed.

Since 2013-16 the design and structure of full-face helmets have changed a lot. They come with better exterior and improved internal liners. Moreover, a new feature has been introduced in the world of helmets, i.e., convertible helmets.

Today, in this modern world, we want everything to do multiple functions. A convertible helmet is made accordingly, as it is a multipurpose helmet. The chin guard of this type of helmet can be removed, so it becomes comfortable as any half shell helmet.

You can remove the chin bar while climbing and enjoy a lightweight, comfortable, and high coverage open face helmet. And chin guard can be attached while descending to have the safety of a full-face helmet because you don’t want any rock striking your face and causing some horrible injuries. So you get two helmets for the price of one.

We have listed some of the best convertible full face MTB helmets so that you can pick the best one without any trouble.

Here is the list of convertible full face mountain bike helmet with removable chin bar.
