Top 10 Picks
1. Bell Super 3R
Removable chin bar
Better fit, lighter weight, and more breathable than previous model
Less secure fit when worn without chin bar
This versatile all-mountain helmet strikes the perfect balance between protection and comfort. With a removable chin strap, riders have the option of full face coverage without the weight and bulk of downhill helmets. It is ideal for riders who need some extra room to breathe on the way up and added protection on the way down. Users who have crashed while wearing the Super 3R have noted excellent face protection and significantly reduced impact during a fall.Read more
This MIPS helmet comes with a detachable chin bar for optional full-face protection during downhills. The chin bar is not as strong as those rated for downhill riding but users note it protects the face surprisingly well during a crash. The adjustable visor is easy to wear with goggles as well for added facial coverage.
The float fit system is easy to adjust for a customizable fit. Riders note feeling very secure when the chin bar is in place. However, the straps attach to the top of the helmet and this causes a bit of movement when worn without the chin bar.
This lightweight and breathable helmet will be a bit more comfortable and less noticeable than the downhill alternatives. Some users note a bit of discomfort due to the exterior straps but most find this to be a great, versatile helmet to keep you comfortable throughout your ride.
This helmet features 23 vents including 6 new brow vents to increase breathability.
Despite the comprehensive coverage, this helmet is surprisingly lightweight, and is actually 10 grams less than the previous model.
This helmet is available in a variety of single color and multicolor designs including some especially for women.
This helmet is a bit expensive considering it's not downhill rated and will likely need to be replaced after one or two big falls. However, for versatility, lightweight, and full coverage many riders feel it is well worth the price.

5. Giro Switchblade
Downhill rating with and without chin bar
Less comfortable for long wear
This 2-in-1 helmet has a downhill rating with and without the removable chin bar. It is a bit heavier and more cumbersome than some of the other options but it offers great protection for those who like to climb everything they go down.Read more
This MIPS helmet has a detachable chin bar and is rated for downhill riding both with and without the chin bar in place. It provides solid protection and deep coverage that extends well over the ears even when the chin bar is not worn.
The Switchblade is available in 3 sizes and features Giro’s patented Roc Loc Air DH fit system for a customized fit. Some users feel it sits a bit low on the brow but most are able to make adjustments for a proper fit.
Plush pads increase the comfort but the heavier weight and slightly decreased breathability of this downhill helmet make it a bit less comfortable for long climbs.
With 20 vents, this helmet has decent airflow. It is fairly good for a downhill helmet but there are certainly more breathable options out there.
This downhill helmet carries a bit more weight than many of the others on this list, but that comes with the territory, since downhill helmets need to offer the most protection.
Available in 9 colors and patterns, this helmet offers a good amount of diversity when it comes to style.
This helmet is on the more expensive end but with the detachable chin bar you can consider this a 2-in-1 helmet with a downhill rating and MIPS safety technology.
6. Kali Protectives Maya Enduro
Molded spot for camera mount
Two-handed fit system
This lightweight helmet comes with a long visor and space for a camera mount. At a lower cost than those with MIPS technology, it offers solid protection and good shock absorption at an affordable price.Read more
Even without the MIPS technology, this helmet is widely regarded to provide great protection for all-mountain riding. Its multi-density EPS foam is designed with crumpling buffer zones that will absorb impact during a crash. Additionally, the longer visor offers some additional eye protection and does more to block out the sun than do many others on this list.
The fit system is the largest complaint about this solid half shell. It requires two hands to make adjustments, making it difficult to fine tune on the trail.
Although it can be difficult to adjust, once the right fit is found, this lightweight helmet is so comfortable that you may forget you are wearing it.
The ventilation system features 5 forehead vents and 7 vents in the rear of the helmet. It does move air through fairly well but it is still not the most breathable for very hot days.
The Kali Maya is very lightweight and has a balanced fit that makes it feel like it's barely there.
This half shell helmet features a long visor for a moto-inspired look. The simplistic design and 7 solid color choices create a cool look that is not too flashy.
This helmet will run a bit cheaper than those with the MIPS technology while still providing solid protection at a reasonable price.
7. Fox Metah
Rear Skull Protection
Not a universal fit
No MIPS lining
The Fox Metah helmet offers more protection around the temples and rear of the skull than a typical road bike helmet without sacrificing much in the way of weight or breathability. Fox designed this to be the perfect all-around helmet for XC but with a bit of MX and even old-school BMX influence and style thrown in.Read more
The Fox Metah offers more protection than the typical half shell with a deep profile and rear to protect lower part of your head. It does not feature the MIPS safety lining but the multi-density Varizorb foam works well to absorb impact.
This helmet has a three position adjustable fit system but some users still find the fit a bit challenging due to the deep profile. Some riders find the front to be a bit too wide and feel it sits too low on the forehead while the back of the helmet feels a bit too tight.
The lightweight, well-ventilated design and addition of moisture-wicking pads makes this helmet great for long rides. Provided you can find the proper fit for your noggin.
The visor sits at a fixed height at the front of the helmet to help conduct air through the three large air vents to keep you cool as you ride.
This helmet gets major style points for the XC inspired design and array of cool color options.
This helmet may run a bit higher in price than other half shells due to the premium design and lightweight feel. At this price you may expect to see the addition of MIPS lining. Fox is known for great design and quality however, so most users were comfortable with the cost.
8. Giro Hex
No coverage for back of the head
Chin straps may be uncomfortable
This breathable helmet offers basic protection at a reasonable price. Reviewers love the customizable fit and ventilated and lightweight design but it lacks coverage for the back of the head.Read more
This lightweight helmet fits snugly but offers minimal coverage. It sits up a bit high and does not provide much protection for the back of the head. It does have a removable POV visor that is easily adjusted vertically to provide additional eye protection without limiting your visual field.
This helmet is available in 4 sizes and is fitted with Giro’s patented Roc Loc fit system. The fit system and easily adjustable straps allow you to fine tune the fit to make the helmet snug enough to stay in place but loose enough to avoid headaches.
The customizable fit and lightweight design make this helmet comfortable for long rides. However, some users complain about the straps being a bit rough on their chin and the pads around the ears may be a bit irritating when you start to sweat.
With 22 vents, this is one of the most breathable mountain bike helmets available.
Lighter coverage and air vents make this a great lightweight option.
Available in a wide array of bright colors that can be stylish but will also help you stand out to cars and other bikers on busy streets or trails.
Price will range on this helmet depending on where you buy it, but the lightweight coverage is much less expensive than the heavy duty mountain bike helmets.
9. POC Trabec
Lightweight with good ventilation
This lightweight helmet offers an innovative fit system that uses buttons and places more weight around the head than right on top. Some users find this unconventional fit to be worth the extra price but others find this helmet to be a bit expensive for the level of protection offered.Read more
Even without the MIPS lining, this tough helmet offers solid protection with a strong polycarbonate shell and layer of impact-absorbing EPS foam. The deep design also provides extended coverage around the sides and rear of the head to add some neck protection.
The unique fit of this helmet places more weight around the sides of your head rather than squeezing it over the top. While this sets the POC Trabec apart from the competition many users find the fit system a bit difficult to get used to as it requires the use of buttons rather than the standard dial.
This lightweight helmet offers increased comfort with its unique distribution of weight.
Sixteen vent slots promote aerodynamic air flow through the helmet to keep your head cool.
The POC Trabec maintains a light weight despite the increased head coverage through its quality design and materials.
The minimalist design and solid color options create a clean and simple look that is far from flashy but still looks cool.
Reviewers can see the quality of this helmet immediately. It does carry a bit of a high price considering it doesn't have MIPS technology. However, it still costs just about half as much as some of the top brands full face helmets.
10. Smith Optics Forefront
Innovative Koroyd construction
Adjustable and removable visor
Built to include a camera mount
Not very breathable
The Smith Optics Forefront features new patented Koroyd material to absorb shock at a lighter weight. The unique design, MIPS technology, and extended coverage in the front and rear of the skull provide great protection. However, it is not the most breathable or affordable option.Read more
The Smith Optics Forefront offers an innovative protection system with Koroyd frame that is proposed to absorb 30% more shock than standard EPS liners. This helmet also offers MIPS technology to reduce rotational force during a fall.
Users find the VaporFit retention system easy to operate and fine tune. Most riders are able to find a comfortable fit without too much tinkering.
Strategically placed padding creates a surprisingly comfortable helmet without resorting to the us of large, plush pads.
Ventilation appears to be the downfall of this otherwise highly regarded helmet. Despite the open design of this helmet, the Aerocore lining does not breathe very well and the vents do not provide adequate airflow when the user is in motion.
The open design of the Koroyd frame makes this helmet very lightweight and easy to wear on long rides.
The Smith Optics Forefront looks nothing like other helmets on the market. The unique Koroyd frame is accentuated by contrasting colors in the aerocore lining for a bold style.
At full price, this helmet is on the expensive end of the spectrum. The quality build, MIPS technology and innovative Koroyd construction help to justify the expense. However, if you do a lot of riding in the heat, the inferior ventilation system will detract from your investment.
Criteria Used for Evaluation
Hopefully, you will never find out firsthand how well a helmet performs in a crash. However, when it comes to protecting your noggin, it's best to hope for the best and prepare for the worst. Mountain bike helmets have come a long way in available safety technology and have made great strides in making these safety features comfortable and easy to wear.
The standard mountain bike helmet has an in-mold construction which includes a hard outer shell to shield the head and a layer of EPS foam to absorb impact and reduce the force on the brain. In recent years, the addition of a MIPS (Multi-directional Impact Protection Systems) has become commonplace to further enhance protection. MIPS is an additional layer that can be added to the helmet in between the shell and the liner to reduce rotational force. When falling from a bike, riders rarely drop directly onto their head. Most of the time the head hits the ground at an angle creating an additional rotational force that was unaccounted for in helmets until the development of MIPS. The addition of this low-friction layer works to reduce that rotational force by allowing the helmet to slide relative to the head. The MIPS liner does carry an additional cost but most riders find that cost of the added brain protection easy to justify.
In addition to varying technology, the physical coverage a helmet provides varies from model to model. From full face styles to compact half shells, there is a wide range in the amount of coverage and protection a helmet provides, so take into account you're riding style, whether or not you want additional face protection in form of a chin guard, and choose the right helmet for you.
Comfort is an important factor when choosing a helmet. Proper fit is a big contributing factor but the addition of pads and having a good weight distribution can also enhance comfort. Most likely you'll be wearing your helmet for hours at a time, so you need it to be comfortable. If it isn't you'll be less likely to wear it, and even if you do you may be distracted by an uncomfortable fit and enjoy your ride less.
Finding a helmet with a good fit is key not only for comfort, but for safety as well. Ill-fitting helmets can bobble and move around your head when you're riding and can easily move around during a crash and not being where you need it to protect your head. On the other hand, helmets that are too tight can squeeze your head and cause headaches. We looked for helmets that can be easily adjusted and can accommodate a wide range of head shapes and sizes.
Safety trumps weight every time so this should not be the main focus when choosing a helmet. However, since your helmet will be sitting on your head for a long time, and we want you to be comfortable and not distracted during your ride, we tried to include only helmets on our list that are at the very least reasonably light. Fortunately, design and materials continue to evolve to allow for the creation of lightweight but effective protection, so a lightweight but effective helmet isn't too hard to find. If you like to go on especially long rides, weight is worth considering more than usual since the helmet you choose will be sitting on your head for quite some time.
Having a breathable helmet with good air flow is key for enjoying your ride and staying safe. First of all, a helmet with good ventilation and breathable will help keep you cool and focused on the trail and enjoying your ride. Secondly, a super sweaty head may lead to your helmet slipping around a lot as you ride, and not being in the right place to protect you if you do happen to fall.
Depending on the time of year and location you ride, this may be more or less important. If you live in a hot area and/or ride frequently during the summer or hotter parts of the day, we suggest you make breathability and ventilation an important factor when choosing a helmet.
Other Factors to Consider
If you ride with goggles or while filming with a GoPro, be sure to take that into consideration when choosing a helmet. All of the helmets on our list are designed to be used with goggles, but especially if you have specialized goggles or glasses you like to use it's good to double check. And some of these helmets don't have a place for a camera or a headlamp so check on that if those are things you like to use when you ride.
Again, it's not as important as safety but it never hurts to invest in good-looking protection you are excited to show off. When riding covered up in safety gear and goggles, your helmet is a good way to make a statement and personalize your look.
Helmets can be pretty expensive, but so are new brains. Just kidding, even if you had the money, you can't buy a new one, so keeping your brain safe is worth an investment. We thought about the price in terms of the safety, comfort, and convenience factors you are getting with your purchase.
Before buying a helmet, it's good to think about how you're going to use it. The type of riding you do plays a huge role in what safety features you choose to invest in.
Typically helmets are divided into three categories:
-Cross Country (XC) is the lowest intensity of the three. With less technical descent, XC riders are at lower risk for high-speed crashes. Cross Country helmets can be lighter in weight and have better airflow while still providing adequate protection for this type of riding.
-Enduro or All-mountain riding is a bit more technical with steeper inclines and bigger drops. All-mountain riders require a bit more protection than XC that covers more of the head. Helmets that offer optional full face coverage such as the Giro Switchblade and Bell Super 3R are great for All Mountain riders as coverage can be adjusted based on the terrain.
-Downhill riding (DH) is the most technical, with long descents and big drops, so it carries higher chances for big falls. For this type of riding a full coverage helmet with a downhill rating is well-worth the investment, and a necessary part of your gear.
Frequently Asked Questions
To find the right size mountain bike helmet you will need to measure the circumference of the largest part of your head by placing a tape measure about 1 inch above your eyebrows and just above your ears. Most helmets have adjustable fit systems to help fine tune the fit for maximum comfort. The helmet should fit snugly with little movement while you ride.
Unlike running shoes and clothing, there is not much benefit to limiting your search to gender-specific helmets. The helmets on this list are all unisex and most come in colors and sizes that will work for everyone.
Obviously a full-face helmet gives you the most protection possible. Most full-face helmets are designed especially for downhill mountain biking, where the speeds can be extreme, the drops huge, and the potential for injury huge.
Even if you don't do downhill, if you want the maximum amount of protection, a full-face helmet is the way to go. However, know that these helmets are hot, heavy, and less comfortable than helmets designed for XC, so be sure to keep that in mind. Most XC riders opt for a lighter, more breathable half-shell helmet that will still offer them good protection.
This is a tricky question, but the short answer is that if you crash and your helmet takes a big hit, it's probably best to replace it. These helmets are typically designed with special zones that are made to absorb the impact of a fall by collapsing in on themselves. They work great, but the downside is that your helmet will need to be replaced if you have a bad fall on it. You may want to contact the manufacturer directly to see what they recommend, and thank them for saving your melon while you're at it.
Well you could, but we don't recommend it. First of all, this is your brain we're talking about, so don't mess around. Secondly, helmet technology has advanced so far recently that a top of the line helmet from 10 years ago isn't even close in terms of the quality and protection that even a bottom shelf modern helmet gives. A few of the helmets on our list start at only around $100, making it easy and well worth it to make sure your head protection is up to snuff.
