We assessed these convertible helmets after considering their weight, comfort, ventilation, protection, and convertibility.
Convertible helmets are becoming popular among riders because of their versatility on the trail. In simple words, you get two great helmets for the price of one.

Not all convertible helmets are certified for downhill riding. So, read specifications carefully before purchasing any helmet.
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. The previous models of convertible helmet were heavier due to extra material attached with them and heavy detached chin bar which you have to add when you have to utilize it. There were also some other issues with them which made them much less attractive to a lot of people.
Now, the convertible helmet has again become the top choice of many people due to its multiple features like delivering optimum level safety in downhill, and breathability like open face helmet when you use it without attaching chin bar. It seems like the convertible helmet has become the first choice of the most of mountaineers and convertible mtb helmet is the future now. It fulfills your multiple needs like it operates as a greater half shell on a local trail and full-fledged downhill helmet at the same time.

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
I tested this helmet in a large size for my 23-inch head size. It fit comfortably and did not squeeze my cheeks. It also felt very lightweight with and without the chin guard. Without the chin guard, its weight is just 0.9lb. And there is no undue movement after tightening its dial knob. Moreover, its smooth chin strap after buckling feels nice on my skin.
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, during testing, I felt it very easy to 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. Its 18 vent openings are integrated with 5 full-length front-to-back channels on the top of the head. During the trial, I found it ventilation system very effective. Its 4 over-brow vents that are also integrated with the air-channel matrix in EPS foam help to maximize cool air circulation over the rider’s head.
One of the most notable improvements that Bell made in this model is spherical MIPS technology. In spherical MIPS technology, the sliding plane is hidden between the EPS core and outer shells. Moreover, its dual-density EPS Core can absorb high and low-speed impact excellently. All these results in enhanced protection & comfort level of this helmet. Last week my neighbor crashed into a rock from 6ft height while wearing this helmet. He did not get a single scratch on his head and face. However, there was a huge dent in this helmet shell and it cracked from the left side. Anyhow, He is grateful to have it and willing to purchase this helmet again. Our testing and safety experts recommended it is safe for enduro racing.
There are 3 soft détentes as I raise or lower its sun visor. During testing, I face no problem with goggles stored underneath its visor when it move to a high position. As compared to the 3R model, its X-static inner pads also have sweat guide channels to drip sweat away from the rider’s brow. I found this feature effective as it keeps my eyes sweat-free in a hot humid environment.
Last but not least, there are two sets of replacement cheeks pads and a removable Go-Pro mount in accessories.
2. Giro Switchblade MIPS Adult Dirt Cycling Helmet
As compared to Bell, the Giro switchblade is a better-looking helmet because it does not have any buckle for chin bar connection. There are only buttons on the left and right sides of the chin bar. If I share my experience, attaching and detaching of chin bar is 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 clicking them in place. Giro switchblade is the most easily convertible helmet in the entire list of our recommendations
From the safety point of view Giro is also best because after detaching the chin guard it offers good coverage to my face and back of my neck. In the full-face mood, it feels like a proper DH helmet. But I felt the Giro switchblade was hotter and heavier than Bell super 3R which is almost the same in price. Without the chin guard, its weight is 1.5lb which is heavy as an open-face helmet.
Its washable inner pad lining is hydrophilic and antimicrobial. According to the manufacturer, these pads can absorb sweat up to 10 times more than their weight but I do not think it’s true, because after 40 minutes of ride sweat start dripping on my ears and neck. However, these pads did not give any sweat smell.
Its Roc Loc Air DH fit system helps in balancing this helmet slightly off the top of the head. It allows more air to pass over my head. Moreover, there are 20 vent openings to allow cool air circulation but I found this helmet relatively hotter. If you need a helmet for a 3-4 hour ride in hot weather then I do not recommend it. This helmet is designed for people in cold countries.
Its Roc Loc adjustment system includes a back knob that helped me to make a quick adjustment with one hand. 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
Moreover, this helmet does not limit my hearing ability because there are two large vent holes perfectly above my ear. However, these vent holes are unable to adopt earbuds for music or call listening. Overall it is the best convertible MTB helmet that offers good head coverage even in open-face mode.
One of my friends had a major crash in it. He was riding too fast and got unluckily hit on a rock. This helmet did a great job by absorbing and distributing crash impact. He did not even get a headache due to its MIPS technology which lets the helmet slide relative to the skull. This helmet’s outer shell got some scratches but did not get any crack. He is completely satisfied with its performance and feels safer with it now. Moreover, CPSC, EN-1078, and ASTM 1952 certification also proved it the best helmet for endure cycling, skateboarding, roller skates, and downhill mountain racing.
3. Bell Super 3R MIPS convertible MTB Helmet Review
Our team recommended this best convertible mountain bike helmet for riders who want a lot of ventilation in both open-face and full-face modes. During the trial, its 4 brow ports after combining with 23 shell vents allow maximum air circulation that feels like air conditioning around my head.
Its 4 brow ports are designed to stop sweat from dripping into the eyes. When I tried my 100% strata goggle with this helmet then these front brow ports also helped to keep warm moist air away from the goggles. During the ride, when I don’t want to use eye wear then I parked it on the top of this helmet without any problem.
Before testing, I found the removal of its chin bar through 3 visible clamps is relatively simple. But one thing that annoys me is its clamp on the backside. Due to this, I felt the need to take off this helmet every time before removing or reinstalling its chin bar. There are two clamps on each side near the ears that are easy to operate but one on the rear side is a little tricky.
In open-face mode, this helmet is lightweight (0.99 lb) and comfortable. After detaching the chin bar, the non-twist-able chin strap made a perfect Y around my ears. Moreover, I did not feel any listening problem with this helmet in full face mood. 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 offers a snug fit and squeezes my cheek a little bit. Anyhow, I felt this helmet was less bulky on the rough trail than the Bell DH version. Its inner pads are easy to remove for washing purposes. According to the manufacturer, its XT2 padding has woven in silver fiber which has anti-microbial properties to keep this helmet free from sweat smell. And I found it’s true, this helmet is free from any kind of smell. After evaluation, our safety experts also approved it as the best enduro MTB helmet in full-face mode.
Its Float fit retention system helps me to do the fitting adjustment with micrometer sensitivity. For my intermediate oval shape head, this helmet sits perfectly and there is no pressure point and undue movement.
During testing, I moved its sun visor up and down with one hand. This easily adjustable visor helped me to keep sunlight out of my eyes. Moreover, there is enough space to park the goggles underneath the visor after moving it to a high position. This adjustable visor is also removable by using a screwdriver. Furthermore, this helmet comes with a “breakaway camera mount.
Its EPS inner core is covered by a hard polycarbonate shell to create a sturdier helmet. This helmet gives excellent coverage to the rear side of my head. Moreover, Its slip-plane MIPS technology adds more protection against the impact of rotational forces. I did not do any crash test on this helmet but after inspection and considering public reviews I am ensured this helmet can do its job perfectly. It is an enduro-style helmet with a removable chin guard but is not certified for downhill racing. It is only designed for enduro racing and trail riding.
4. Bell Super DH MIPS Adult Mountain Bike Helmet
BELL Super DH is the only convertible helmet that is certified for downhill riding or BMX racing. BELL Super Air R and 3R are the best trail MTB helmets but are not certified for downhill cycling. However, high-end protective features make this helmet expensive and heavier than other BELL convertible helmets. Our experts recommended it as the safest convertible helmet for downhill riding.
Moreover, its chin straps come with a magnetic FIDLOCK buckle. After adjusting the chin strap length I found its magnetic buckle easy to manipulate with one hand. Its mechanical engagement keeps it securely locked.
During the evaluation, I removed its chin bar through 3 visible clamps without much effort. But I have to take off this helmet before removing or re-installation the chin bar. Its two clamps on each side near the ears are smooth to operate but one on the backside is a little stiffer.
Its variable density EPS foam is designed to minimize energy transfer to the rider’s brain from different speed impacts. Moreover, its most advanced flex-spherical MIPS technology takes this helmet protection ability to the top level. I felt super safe in this helmet. According to our survey report, this helmet has won people’s confidence by saving their lives in some serious accidents.
Its X-static pads are designed in such a way that they can channel the absorbed sweat to drips away from brows. I found its guide sweet pads helpful to keep my goggles moist-free. Moreover, These X-static pads are also washable. The pads are attached to the helmet interior with Velcro tape. I feel this helmet a little bit tight on my cheek in full face mood 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 my head. During jumping, it did not loosen itself due to vibration. This dial also 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 a large size that sits comfortably on my head without any undue movement.
Its ventilation system has 2 brow ports and 19 helmet vents that allow good air circulation around my head. But I did not find its ventilation as effective as Bell super Air R. However, its brow ports work well to evaporate sweat from my forehead. Overall it is the best helmet for endure and trail riding.
Moreover, its adjustable visor can accommodate both goggles and glasses. I try to remove its visor with a screwdriver and it’s removable. Furthermore, Its Seamless camera mounts require no zip ties or tape. According to the manufacturer, its visor and camera mount are designed to break away upon impact which can also minimize injury risk.
5. Sweet Protection Arbitrator MIPS Helmet
It is the best convertible MTB helmet without any compromise on safety. According to the manufacturer, this helmet has an internal structure that is made of Zytel thermoplastic material. This internal frame goes through the whole helmet to make a very strong and rigid shell. Our safety expert also marked this helmet best for downhill racing in full-face mode. Its chin guard is made of carbon fiber but the upper shell is made of thermoplastic material. Moreover, it comes with a standard MIPS system to add more protection against rotational impacts. To be honest. I have no crash experience with this helmet but I am ensured this helmet can do its job perfectly.
Its chin bar connecting mechanism is pretty secure. There are two stainless steel and one carbon fiber tab on the chin bar which slot into the internal frame of the Zytel material. There is a need to pull or push a handle lock in the back to remove or reinstall the chin bar. However, I found the chin bar disconnecting mechanism simple but reconnecting is tricky. First time to pull off this task I was really afraid to break the helmet. But after some practice it becomes easy. However, Putting on and off this helmet does not feel comfortable to me. Moreover, there is a need to take off this helmet every time before attaching or detaching its chin bar.
Dual flow ventilation through 3 brow ports and 15 helmet vents allows reasonable airflow around my head. Its brow ports also helped to keep my goggles moist-free by quickly evaporating sweat from my forehead. According to the manufacturer, its STACC vent channels are designed to intake and exhaust air through arteries which can maximize airflow for the given number of vents. But I did not find its ventilation system more effective than BELL helmets. This helmet is designed for moderate weather conditions. I did not recommend it for people in hot countries.
There is an OCCI-grip turn dial in back to adjust the size. During the trial, it did not loosen itself. The manufacturer also included two sets of chin straps to limit compromise in this helmet fitting. One strap is for half-face mode and one for full-face mode. But every time there is a need to hide the chin strap of half shell behind the ear pads of the chin guard. Moreover, putting on this helmet is not as comfortable as wish to be.
To enhance protection ability manufacturer adds some extra weight to this helmet design. I feel it is a little heavy on my head as compared to other convertible helmets. Without the chin bar, its weight is 1.1lb which is not up to an uncomfortable level.
Last but not least, there are two sets of Inner pads of different thicknesses to do fitting adjustments according to your face shape. Moreover, you can also park goggles underneath its visor.
6. DEMON UNITED MTB Helmet with removable chin-bar
I chose this helmet based on its good appearance and attractive price point. I am impressed with its construction quality. It sits well for my 23” head size. But during the test on a rough trail, this helmet changed position on my head and I readjusted it by tightening the dial knob. However, this setting put pressure on the back of my head. I resolved this issue by changing the thickness pads that come with this helmet accessory. These check pads feel nice and maintain sung fit for my next ride.
During the examination, it felt easy to take off its chin guard but difficult to reattach it. Giro Switchblade has a relatively smooth chin guard installation mechanism as compared to this helmet. I have to take off this helmet every time before chin guard installation. However, its chin guard is lightweight I barely know the chin guard is there after attaching it.
During the trial, its 20 big vents opening allows cool air to pass directly over my head. After testing at different speeds I rate this helmet as a good ventilated helmet. Moreover, after tune fit tension and changing thickness pads this helmet fit so sung that I barely notice its weight. However, one thing that annoys me is its back side does not have any padding. Overall its fitting is just right for my noggin.
In-mold construction of the outer shell with polycarbonate material makes this helmet strong and lightweight. But it does not have the impact-absorbing MIPS technology. So, this helmet is perfect for beginner or hobby trail riders. I would not recommend this for riding speeds more than 12mph. it is not rated for downhill racing. For hobbies, it becomes the best trail MTB helmet for the all-day ride in summer.
This helmet can also easily accommodate goggles and sunglasses. There is enough space to place goggles above your brow by moving the visor to an up position. However, its chin strap and dial knob need some built-quality improvement. It is only CPSC certified; it does NOT have the Downhill/BMX or ASTM F1952 certification
7. Lixada Kids convertible Helmet
I purchase this helmet for my 9-year-old son because he likes the look and graphics on it. His friend also has this helmet that makes my son want to wear it. For the price, I am satisfied with this helmet-built quality. Its decorative style looks cool on his head. My son found it lightweight and never complained about it being uncomfortable.
The first time when my son wears this helmet, it slides a little down on his eyes which obstructed the view. To resolve this issue, I replaced it inner pads of 8 mm thickness with 12 mm thickness. After that, he is pleased with its sung fitting. My child also feels easy to do the fitting adjustment through its dial knob with one hand during cycling. Moreover, its padded nylon chin strap with clip buckle also helps to keep table this helmet in the correct position.
According to the manufacturer, this helmet has 4 layers of protection. Its Strong and hard polycarbonate shell covers the EPS foam and the EPS foam covers by sponge pads. All these layers help to minimize impact pressure and improve the overall safety performance of this helmet.
No doubt, this helmet offer basic protection in all child sports activities like skateboarding, roller skating, scooter, electronic board, and mini bike riding. However, I will not recommend it for a higher rate of speed other than a bicycle
This convertible helmet is specially designed for kids. So, every kid can easily switch between half and full-face mode by pushing both buttons above the ears. However, I felt it pops off very easily and doesn’t seem very protective. But for the child, it is safe enough. My son usually does not removes it and feels secure in it.
One thing that my son does not like is its fixed visor position. On sunny days it can keep sunlight out but also obstacles the view field in the evening. Moreover, its washable inner pads are held on with small strips of Velcro that fall out sometimes.
Last but not least, this best convertible MTB helmet is designed aerodynamically. My kid has worn this helmet for all-day sports activities in summer. He got sweaty a little bit but did not complain about his neck strain.
8. Leatt 3.0 Enduro V21.2 Adult convertible MTB Helmet
If you are looking for something new other than the famous bell 3R convertible helmet, then this helmet is another solid option for you. This great-looking helmet is a little bit cheaper, lighter, and smaller in the back than the bell super 3r helmet. It is not a downhill certified helmet like bell super DH and Giro switchblade but it can offer the best protection as an enduro bike helmet.
Leatt calls inner blue donuts as turbine, and this 360 turbine technology is similar to MIPS. It can reduce the 40% impact of rotational accelerations. During the evaluation, this helmet offers the best coverage to my head even in half-face mode. Our head of the testing team marks this helmet safe for the rider who pedal to the top of the aggressive trail.
During the trial, I found this helmet ventilation very effective like Bell super 3R helmet. Moreover, I also found chin bar removal or installation mechanism is convenient but I have to taking-off this helmet before switching.
There are extra cheek pads in accessories to do fitting adjustments. Furthermore, this helmet design is goggles friendly. But goggle storing underneath the visor is not very easy because of limited visor movement. Overall, it is the best enduro mountain bike helmet.
Lazer Helmet Revolution FF MIPS helmet
This is one of the lightest downhill certified helmets with a removable chin bar. In this helmet, you can snap extended ear covers in place after removing the chin guard. As compare to other convertible helmets, there are 6 screws to attach the chin bar with this helmet. But you need a screwdriver or a coin to installing or removing these screws. Moreover, you can adjust 9 different setups by installing or removing helmet parts like chin guard, sun visor, and ear cover.
Another unique thing in design is the helmet back which can hold the goggle strap very well. Moreover, you can park the goggles underneath its adjustable visor easily.
Rubberize dial knob of the advanced fit system is easily accessible. During the trial, this helmet offers deep coverage to my head in both half face and full face modes. Furthermore, its 23 vents opening that keep my head cool in hot weather conditions. This Lazer revolution helmet promises rider safety for enduro riding in full-face mode. When it comes to trail helmets without chin bar I find this helmet lightweight 457g and pretty comfortable. Overall it is the best convertible mtb helmet.
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 helmets for further fitness improvements.
An important thing to consider while buying the helmet is to try 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.
