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.

What are Convertible full face MTB 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.

Which helmet is better open-face or full face?

Both have some pros and cons. But if we look for safety, then full-face helmets are better because they can protect your head as well as they offer excellent chin protection, reduced noise levels, and no bug-to-face contact. On the other hand, half face helmets provide protection to the head only and also do not prevent you from dust and debris. However, in terms of ventilation, half face helmets are best suited.

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

Things to Consider Before Buying a Convertible Full-Face MTB Helmet (Buying Guide)

Below are the things you should note while buying a convertible full-face MTB helmet:

Comfort padding

To maintain the stability and comfort of the helmet, and to manage heat effectively, internal cushioning is crucial. 

Since pads absorb a lot of sweat, they should be removable and washable; materials should also be considered because fabric materials are not all equal when it comes to next-to-skin comfort. 

As an alternative to thicker retention systems, some lids use different pad densities to customize the fit. However, thicker pads can also be more uncomfortable and hotter.


In addition to keeping the sun out of your eyes, the MTB helmet’s visor should be tilt-adjustable, rattle-free, and stable. 

The flexible material and easy-to-break away fixtures also make visors safer as they prevent them from twisting your neck if an accident occurs.

Also, if you use a visor, it better be good-looking, even though it may not even be visible when you’re on your bike. 

Attachment to Chin bar 

The chin guards on certain helmets can be removed so they can be used in uphill and downhill settings. 

The clamps used by each system offer the best fitting quickly and easily while the helmet is on. 

Further, the chin bars are designed to meet the safety standards of trail riding as well as full DH certification.

The ventilation system

In order to cool the head, openings and vents are essential. The central cooling component of helmets is the intake (front) and exhaust (rear) vent-channelling system. 

This system controls the temperature inside the helmet by channelling air through channels or grooves. 

In addition to reducing helmet weight, vents may also improve appearance when used carefully. 


Helmets need to be strapped safely, but the straps must also be comfortable and easily adjustable so these straps do not dig into ears or jaw lines. 

A magnetic clasp is often used on helmets to make installation faster, however, a lighter, less noticeable plastic clasp is more preferable.

Features for safety

Many lids offer rotational impact protection in addition to hard shells and multiple densities of foam for absorbing impacts. 

MIPS is probably the most known one, which uses a non-abrasive plastic liner that slides independently of the outer shell and helps to disperse impact energy. 

Additionally, there are other own-brand versions all with similar objectives.

Standards of protection

In order to be sold in the public domain, all MTB helmets must meet ‘minimum standards’. 

Various characteristics of the helmets are considered including strap integrity, puncture resistance, and impact handling. 

Helmets certified by DH can withstand greater forces but weigh more (and require more material).


The usual retention system consists of a cradle that fits snugly over the head. 

A good strap should fit evenly, tighten easily with one hand, and have a tilt and circumference adjustment to fit all head shapes. 

Be wary of flimsy plastic adjustment systems too, as they tend to deteriorate over time.

Goggles compatible

A requirement for some is the ability to wear goggles beneath the visor, which requires a suitable amount of space. 

It’s hard to see why goggle clips are necessary since elastic straps can do the job just as well. 

Eyewear stow points are also available on some helmets, which will be useful for those who wear glasses.
