Are you looking for a full face mountain bike helmet? After performing exhaustive research on over 50 full face mountain bike helmets, we purchased twelve of the most intriguing options. We spent six weeks wearing these helmets as much as humanly possible. We rode shuttle laps, ripped bike park laps, and we even climbed wearing all of them. Heck, we even wore them while writing this comparative analysis. Yes, these are all highly-functional helmets, but they each have their inherent strengths and weaknesses. We carefully evaluated these helmets based on several important metrics to find the best helmet for you, your riding style, and your bank account.

Our Editors' Choice Award for the best full-face downhill helmet goes to the Fox Rampage Pro Carbon Weld, which took the highest overall score in our test. This top-of-the-line helmet features the latest and greatest in safety features, including Fluid Inside technology that reduces the forces to the brain in the event of angled impacts and protects against linear impacts. Also, a clever magnetic break-away visor intentionally releases on angled impacts. This helmet is heavy, but it boasts exceptional airflow.

This helmet isn't perfect. There are some quirks to the fit as well as a pressure point on the forehead. If you are in between sizes, we recommend thinking about sizing up. Also, the Rampage Pro Carbon is expensive but if you're willing to spend the money for the best downhill helmet on the market, we think this is it.

Supreme value
Lightweight for a budget helmet
Poor ventilation

Large fit

The 7Protection M1 is a supreme value. This helmet delivers rock-solid performance at an eye-popping price tag. This lid is a fantastic option for the person just dipping their toes into the gravity scene and doesn't want to break the bank. Protection levels are decent, and this helmet is surprisingly light for a budget-focused helmet.

The M1 isn't quite perfect. The 7Protection helmet has a warm and stagnant feel. Warm air and humidity don't escape all that effectively, and the result is a sweaty and hot melon. The poor ventilation theme continues at the chin bar as the ventilation ports on the chin bar aren't very effective. One other minor quirk is that the end of the visor is strangely narrow. Regardless, this is a quality helmet at a very reasonable price.

The Super DH MIPS is our favorite convertible helmet. You're purchasing a downhill certified full-face helmet that works well as a half-shell trail helmet too. This makes this a fantastic option for enduro racers or someone who simply want one single helmet to do it all. In full face mode, this lid has a light feel and excellent visibility.

This helmet is not as robust as some of the purpose-built downhill helmets. As a result, if you are just looking for a helmet to wear at the bike park, we recommend looking elsewhere. In trail mode, this is a stellar and reliable half shell that breathes well.

The Troy Lee Designs Stage MIPS is our top pick for enduro racing. This feathery helmet has excellent ventilation. This superb airflow provides an excellent oxygen supply when mashing the pedals on an enduro stage and also keeps the crown of your head quite cool. The Stage helmet has an excellent range of vision thanks to a chin bar that is tucked out of the way. This helmet is downhill certified.

This helmet has a somewhat narrow range of application. It is built for enduro racing. Despite the downhill certification, we would recommend something more substantial for downhill and park riding. Even with the supreme ventilation, we would still recommend a convertible lid for embarking on big climbs to get to the top of rowdy downhills. This isn't a great choice as an only full-face helmet. It is best suited as second helmet for race days.

Why You Should Trust Us


This review is brought to you by OutdoorGearLab Review Editors Pat Donahue and Dustin Schaad. Pat co-owns Over the Edge mountain bike shop in South Lake Tahoe, and has been heavily involved in the bike industry for the past eight years. He rides several disciplines, from downhill to long rides and dirt jumps. Pat is joined by Dustin, a former professional mountain biker and Red Bull Rampage participant. Both Pat and Dustin bring to this review a wealth of downhill experience and understand the finer points of head protection.

Before donning any lids, this comparison started with researching the market. We initially considered over 45 models before selecting the 12 most promising ones, which are discussed here. Aside from measuring each helmet's weight, all testing was conducted in the field. Testing took place throughout the mountain west, from the Lake Tahoe area to the Whistler Bike Park and points between.

Analysis and Test Results


You should always be wearing a helmet when riding a bicycle. Whether you are riding to the corner store to buy some milk or sending a road gap in British Columbia, helmets are critical. Full face helmets are the best option when the things get steep, and the rowdiness gets cranked to 11.

Full Face helmets come in all shapes and sizes.

Our expert testers spent months riding and rating each helmet we bought for this review. We compared these helmets based on experiences on the trails and inspection in our lab. Every helmet was scored across six performance metrics. The combination of these scores produced the overall ratings. Below, we highlight the star performers in each category. This will help you identify the right model for your specific needs based on which metrics are essential to you.

Value


Value isn't one of the scored metrics in our review. That said, we recognize the extreme importance of getting a good value. There's no doubt that mountain biking is expensive. For downhill helmets, there is a wide range of price. The 7Protection M1 is our best buy winner for its supremely impressive price tag and reliable performance.


Comfort


Comfort is a critical metric. A comfortable helmet allows riders to focus on the trail or feature in front of them and not a pinch or pressure point in the helmet. Full face helmets can only be so comfortable, and you'll likely never forget that your head is stuffed into a padded bucket, but some helmets are far more comfortable than others.

The most comfortable helmets have interior padding constructed of dense open-cell foam covered in a soft-to-the-touch, wicking, materials. This padding tends to pack out over time, especially in the cheek/jaw pad area where it is the thickest. Once the material packs out, it becomes less comfortable, and the fit gets wonky, causing the helmet to flop around more than when the padding was robust.


The Bell Full 9 Carbon is the most comfortable helmet in our test and we awarded it the elusive perfect 10 in this test. This model uses dense interior padding which is covered with a smooth, velvet-like material to hold the helmet in place while preventing pressure points between the head and the polystyrene. The Giro Disciple is another exceptionally plush full face that is tremendously comfortable against the face. The Best Buy winner, the 7Protection M1 is another exceptionally comfortable helmet, especially for the impressive, budget-friendly, price tag.

Protection


We awarded each helmet a relative protection score based on the certification standards that it meets as well as a close inspection of its construction. The beefier and heavier duty downhill specific full-face helmets generally scored the highest in this metric. The lighter duty enduro oriented models and those that are convertible tended to score a little bit lower. This is not to say that they aren't protective, but we feel that the increased ventilation holes and lighter weight materials and constructions may not protect you as well as the heavier duty DH models.


We did not perform any scientific crash testing on the helmets; we will leave that to the certifying agencies. We did do some unscientific crash testing when things didn't go as planned, and we were forced to devour a couple of dirt sandwiches. We did have one particular hit on the TLD D3 and it came out pretty much unscathed and the rider in decent shape too. We scored the Editor's Choice Fox Rampage Pro Carbon at the top of the heap in this metric. It has excellent coverage, a stout carbon shell, breakaway visor, and Fluid Inside technology. Other models like the Giro Disciple, Troy Lee D3, and 100% Aircraft aren't far behind and are the lids we'd reach for if we were headed to the bike park to ride chairlifts all day.

All the helmets in this review offer varying levels of protection that are related to their intended uses.

Of the enduro models we tested, the Fox Proframe Moth scored highest in terms of protection while the Bell Super DH MIPS was our highest rated convertible model.

Weight


The average weight of our downhill-specific full face helmets in our test is 39.5 ounces. The average weight of our enduro-oriented options is about 28-ounces. For comparison, the average weight of the half-shell helmets in our mountain bike helmet test was around 12.5-ounces. This means that full-face helmets are around three times heavier than half-shell helmets. It's hard to quantify how much more protective a full-face is compared to a half-shell, but we think they cover between two and three times more of the head and offer a sturdier construction. The weight-weenie crowd might skip the protection of the full-face altogether and save twenty or more ounces by rocking a half-shell. That said, the weight weenie crowd likely isn't spending a huge amount of time at the bike park. It's pretty easy to justify the extra ounces to keep your teeth intact when ripping DH laps.


As with half-shell mountain bike helmets, those that fit securely felt lighter than the scale may reflect. One such model was the Fox Rampage Pro Carbon Weld, which at 43.5-ounces is one of the heavier helmets we tested, though it's snug fit makes it feel lighter on the head than the numbers suggest.

Another exceptionally portly helmet in our test is the Giro Disciple MIPS, which despite its plush, comfortable, and secure fit, feels much heavier on the head than any other helmet we tested. We think the Disciple MIPS is an excellent helmet, especially for the price. We suggest not being too concerned with the weight, especially for such a downhill-focused helmet.

The 7Protection M1 is lightweight despite its impressively low price tag.
The 7Protection M1 is lightweight despite its impressively low price tag.

The Troy Lee Designs Stage MIPS is the lightest helmet in our test at just 24.3-ounces in size medium. As we noted in the review, we don't consider this helmet a great option for full-blown downhill shredding. This is an enduro-oriented helmet that is downhill certified, but there are better options for park laps. The Fox Proframe Moth is another feathery enduro lid that weighs 25.9-ounces.

Our Best Buy winner, the 7Protection M1, is a lightweight full-face helmet that delivers a stellar value. At 33.4-ounces, it is one of the lighter options in the test. That said, the protective values may be lacking compared to the spendier, heavier options.

Ventilation


Our ventilation metric considers two types of ventilation.

First, we considered how well each helmet allows cool air to flow into the helmet and transport built-up heat away from the head.


The second aspect is how well each chin guard allowed the rider to breathe. This type of ventilation is influenced by the size and shape of the chin guard as well as the size and materials of the vents in the guard. A significant factor in how well a helmet allows the wearer to breath is the proximity of the chin guard to the mouth. The other is the quality of material in the vents on the chin bar. Some of our enduro-focused helmets have no venting mesh or plastic, just a wide open hole, these obviously breathe the best. Keep in mind that full-face helmets will never offer quite the same airflow as a half shell. That said, some full faces breathe significantly better than others.

The highest score in this test went again to the Troy Lee Designs Stage MIPS with the Fox Proframe Moth close behind. We would like to reiterate one thing: both the Stage MIPS and the Proframe designed squarely for the Enduro crowd. These helmets have the safety certifications, but they simply aren't meant for bike park day and downhill racing.

Among the most protective helmets, the Fox Racing Rampage Pro Carbon is the most well-ventilated burly helmet. The 19 vents feature both intake and exhaust ports to pull in cool, fresh, air and pull it through the helmet and then exit the rear. The 100% Aircraft is another noble performer in this metric. The 25 vents and their location on the helmet allow for excellent airflow, and the mouth guard also gives way to a nice feel and good circulation through the chin area.

Large vents on the chin bar of the Rampage Carbon help keep the air flowing on long and arduous downhill runs.

Visor


Visors serve to shield the eyes from sun, rain, or mud, depending on conditions. All of the helmets in our test have visors. In fact, the visor is a primary and critical feature in a mountain bike helmet. It is especially important on a full-face helmet.


The visors on our test helmets vary in both length and width. Another critical difference is how the visor is attached and secured. Almost all of the visors are attached with two removable screws on either side of the helmet near the temples. These screws allow the visor to pivot up and down a few degrees to adjust for conditions. These screws are typically thumbscrews that can be manipulated without a tool. For added security, a coin works in cranking them extra right.

An example of a visor mounted with two screws. Note the absence of a middle screw.
An example of a visor mounted with two screws. Note the absence of a middle screw.

Many of our test helmets, like the Troy Lee Designs Stage MIPS and the 7Protection M1 have a third screw in the center of the visor. This screw is positioned under the visor and is attached to a slider mechanism. Simply loosen the middle thumbscrew and slide the visor up or down on the track.

We came to prefer helmets with three rather than just two thumb screw attachments. They allow you to more or less leave the side screws by the temple alone. Simply use the center screw for all adjustment purposes. The Fox Proframe and Bell Full 9 Carbon utilize the two-screw method and require both screws to be loosened to move the visor. We found that on some occasions, the visor ended up a bit crooked.

The Fox Rampage Pro has a magnetic visor that is designed to come off in the event of a crash.
The Fox Rampage Pro has a magnetic visor that is designed to come off in the event of a crash.

Our Editors Choice Fox Rampage Pro Carbon Weld has a fixed visor that doesn't adjust. This is a safety feature that is designed to allow the visor to break away cleanly and easily in the event of a crash towards the face. This reduces rotational forces by getting that visor out of the way instantly as to not to interfere with the safety features working inside of the helmet.

The Troy Lee Designs D3 and 100% Aircraft MIPS both posted nice scores among our aggressive, downhill focused helmets. In terms of our enduro-focused options, the Bell Super DH MIPS and Troy Lee Stage MIPS were the most impressive.

We're big fans of adjustable visors that flip up so we can stash our goggles on climbs or when riding the chair.
We're big fans of adjustable visors that flip up so we can stash our goggles on climbs or when riding the chair.

Visors are typically much more flimsy than the rest of the helmet. This is by design; most are designed to break away in a crash. Unfortunately, visors are typically designed for a specific model and are not compatible with other helmets. For this reason, if you damage a visor in a minor crash that doesn't total the helmet, you have to track down a replacement specifically for that helmet. The Troy Lee D3, which came with an extra color matched visor, is the only helmet to include a spare.

Durability


Full-face helmets are typically more durable by design than other types of helmets. One area of weakness we identified in our half-shell helmet test is the bottom edge of the helmet. Helmets which have exposed polystyrene foam along the bottom edge do not hold up to day-to-day use as well as helmets which keep the polystyrene protected. Full-face helmets do not suffer from this weakness since all of the impact absorbing foam is encased within the shell.


We did not do any scientific crash or durability testing of these helmets. Instead, we just wore them day-in and day-out while riding, and examined how well they held up. The most impressive helmets in this test were the Bell Full 9 and Fox Rampage Pro Carbon Weld, which came through our test with almost no signs of wear. Other helmets we tested did not fare as well.

Extras


The downhill helmets we tested came with a variety of extras ranging from spare visors, helmet camera mounts, and speaker pockets. All came with a storage bag. Most of these bags are simple fabric sacks, except for the ones included with the Troy Lee D3 and Fox Rampage Pro Carbon, which came with a substantial storage bag that can also accommodate goggles, gloves, and a few other small items.

We really liked the Troy Lee D3, which not only includes the sturdy storage bag but also includes an extra color matched visor, should you damage the first one. We think that these two extras are likely to get used along the course of the helmet's lifespan.

Downhill helmet testing is hard work. We promise.

Conclusion


Making an educated purchase decision is an involved but straightforward process. We suggest strongly considering the style/discipline of mountain biking you plan to be doing, the terrain, and your bike prior to selecting a helmet. This review is designed to help you choose the most appropriate helmet for your mountain biking needs. We hope it helped!
