What is a convertible helmet? (A comparison between convertible and non-convertible helmet)
Convertible mtb helmets are full-face mtb helmets with removable chin bars. It becomes open-face if the chin bar is missing.

Convertible mountain bike helmet Reviews
Below listed helmets are provided with their genuine information. Moreover, we have tested each helmet before describing its pros and cons. So, it becomes very easy to choose the right helmet according to your requirements.
1. Bell Super Air R MIPS Convertible MTB Helmet Review
In simple words, Bell super air R is the updated version of bell super 3R. This latest model resolves all the issues of Bell super 3R but its high-end features cost some additional price. During the examination, I found its chin bar removal or re-installation mechanism is more convenient than super 3R. In this latest model, the chin-bar back buckle is eliminated. So, everyone can remove or reinstall its chin bar without taking off this helmet.
Moreover, this helmet weight is 144 grams less than bell 3R. Bell Super Air R has a lot of vent openings. There are 18 vent openings integrated with 5 full-length front-to-back channels on the top of the head. I found this helmet ventilation system very effective. Its 4 over-brow vents are also integrated with air-channel matrix in EPS foam to maximize cool air circulation over rider head.
One of the most notable improvements that Bell made in this model is spherical MIPS technology. In spherical MIPS technology, there is an inner EPS core that sits firmly against your head and the sliding plane is now hidden between EPS core and outer shells. All these results in enhanced protection & comfort level of this helmet.
There are 3 soft detentes as you raise or lower the sun visor. During the trial, I face no problem in goggles storing underneath the visor after moving it to a high position. As compare to 3R, its X-static inner pads also have sweat guide channels to drip sweat away from your brow. This feature is very helpful to keep your eyes sweat-free in a hot humid environment.
The protection level of this best mountain bike helmet is enhanced by adding dual-density EPS foam. Dual-density core gives excellent protection for high and low-speed impact. Our testing and safety experts recommended it as best enduro mountain bike helmet.
Last but not least, there are two replacement cheeks pads and a removable Go-Pro mount in accessories.
2. Giro Switchblade MIPS Adult Dirt Cycling Helmet
Giro switchblade offers the best coverage to my face and head like a full-face helmet. After detaching the chin bar, there is still excellent rear head and ears coverage. Moreover, the Giro switchblade is the most easily convertible helmet in the entire list of our recommendations. But I felt Giro switchblade hotter and heavier than Bell super 3R which is almost the same in price.
To detach the chin bar there are buttons on the left and right side of the chin bar. Attaching and detaching of chin bar becomes simple for me after some practice. I did not feel any need to take off this helmet to reinstall the chin bar. Everyone can do it by just aligning metal lugs and click them in place.
The washable inner pad lining of this helmet is hydrophilic and antimicrobial. These pads can absorb sweat up to 10 times more than its weight without giving any sweat smell. Its Roc Loc adjustment system includes a back knob that help to make a quick adjustment with one hand. Moreover, its MIPS technology lets the helmet slide relative to the skull and adds more protection against the rotational force transfer to the brain.
For my intermediate oval head, I did not experience any pressure point or undue movement due to its rubber-padded cradle. During testing, I moved the visor up and down in 4 steps with one hand. It helped me to keep sunlight out of my eyes in every situation. These 4 steps include three riding positions and a high position to store the goggles above your brow.
It’s Roc Loc Air DH fit system helps in balancing this helmet slightly off the top of the head which allows more air to pass over the head. Moreover, there are 20 vent openings to allow cool air circulation but I found this helmet relatively hotter. However, this helmet does not limit your hearing ability because there are two large vent holes perfectly above your ear. Overall it is the best convertible MTB helmet that offers good head coverage even in open face mode.
Moreover, CPSC, EN-1078, and ASTM 1952 certification proved it the best helmet for enduro cycling, skateboarding, roller skates, and downhill mountain racing.

There are two clamps on each side near the ears and one on the rear side of the helmet.
In open face mode, this helmet is very lightweight (0.99 lb) and comfortable. After detaching the chin-bar, the non-twist-able chin strap is still part of the helmet. Moreover, I did not feel any listening problem with this helmet on my head. In open face mode, this helmet is the best for trail riding. But there is a need for a backpack to carry the chin bar after detaching.
Its chin bar with cheek pads not only offers a snug fit but also makes this helmet less bulky on a rough trail. Its inner pads are easy to remove for washing purposes. Moreover, its XT2 padding has woven in silver fiber which has anti-microbial properties to keep this helmet free from sweat smell. After evaluation, our safety experts also approved it as the best enduro MTB helmet in full-face mode.

The pads are attached to the helmet interior with double side tape. I feel this helmet a little bit tight against my face but it’s not up to an uncomfortable level.
Its float-fit race system is featured with a rubber over-molded dial that is suspended off the back of rider head. This dial allows me to do the fitting adjustment with micrometer sensitivity. My head shape is intermediate oval and has a circumference of 23″. So, I try large size that sits on my head comfortably and there is no pressure point.

Buying guide for choosing the best convertible mtb helmet
Fitting: The most important factor of mountain bike helmet
The most important factor to prioritize while choosing the mountain bike helmet is the shape of your head. Everyone has a different shape of head so it is difficult to design a single helmet for all. Some helmet might fit very well on the head of certain people and highly unfit for many others. You might not face this issue to a such a large extent when you have an open face mtb helmet as it comes with a built-in retention system. But on the other hand, the full-face mountain bike helmets just come with limited one thinner and one thicker set of pads in it. This is a point where convertible helmets have an edge over typical full-face mountain bike helmets.
Convertible helmets come with built-in retention system for perfect fitness and chin bar for more adjustments. Moreover, a second set of cheek pads also come with convertible helmet for further fitness improvements.
An important thing to consider while buy the helmet is trying the helmet personally. If you don’t buy them from local store then the online store must have a good return policy, so you can exchange it easily if it is not compatible with your melon.
