Giro Fixture Bike Helmet with MIPS
On the very first spot of our list is this amazing Giro Fixture helmet. It is incredibly lightweight, weighing a little over 1.9 lbs! This model is an open helmet made from in-mold polycarbonate. You’re protected by the superb-quality EPS and MIPS liner. Now, Giro offers two Fixture models: with MIPS and without MIPS. We’re recommending the with MIPS model to you.
There’s a visor that’s built right on the helmet. You cannot adjust the visor like that on full-face helmets. It is fixed in to place when you put it on. However, you can remove the visor if you don’t need it. What we love about this Giro helmet is its design. You can see those little diamonds or rectangle-like open vents. These allow breezy ventilation so you won’t be bothered by sweat too much during your trip.
This helmet is universally sized to fit head circumference from 54 – 61 cm. There’s no GoPro mount that ships with the helmet, unfortunately. However, you can get one on Amazon for very cheap and mount it on the helmet. We love the matte finish. Plus, there are so many colors to choose from. Overall, this is a safe, light, and super cheap helmet that’s totally worth the money!
- MIPS protection
- Super lightweight
- Built-in visor
- Adjustable straps
- Breezy ventilation
- Universal size
- Super nice colors
- No GoPro mount
Troy Lee Designs All Mountain Mountain Bike A1 Classic with MIPS (Medium/Large, Black)
Moving on we have the super protective and lightweight Troy Lee Designs A1 helmet. It’s even lighter than the Giro we saw earlier: 1.5 lbs! Simply love it! This helmet is seamlessly integrated with MIPS, thanks to the reinforced polycarbonate shell and high-quality EPS.
The design of this helmet is thoughtful and clever. You’ll get 8 pressurized intakes to draw cool air in and 8 vents let hot air out. This gives the perfect ventilation for riders in even super hot weather conditions. You can adjust the helmet at three levels for maximum comfort. For example, you can adjust it up a bit when wearing protective eyewear.
What’s nice about this helmet is that you can remove the inner liner and wash it easily. It’s made from anti-microbial and moisture-wicking material so you’ll get dry and comfy feeling every time you wear your helmet. This is a Medium/Large size that would fit head circumference of a little over 50 to 60 cm.
Overall, this is a great buy. We definitely recommend getting one for yourself on your next singletrack, dirt jumps, or cross country adventures!
- Highly ventilated
- Super strong materials
- Comfy liner
- Incredibly light
- Washable Liner
- Adjustable retention
- Anti-bacterial foam
- A bit pricey
Bell Super 3R MIPS MTB Bike Helmet
This Bell Super 3R is a cool, safe, and lightweight full face helmet. The construction is made from durable polycarbonate. The inner padding is very comfortable. And the overall helmet is fully integrated with MIPS.
You’ll absolutely love this one because you can mount your camera or GoPro on it super easily. There’s a full face visor (some folks call it a face guard) that comes with the bike. It helps protect you from very bright sunlight, dirt, or splashes of water. You can totally adjust the visor up and down on three notches. Super convenient!
Also, the ventilation of this helmet is another excellent feature. You’ll get 23 vents, 4 brow ports, and 6 chin vents. It does not feel hot wearing this at all. Especially when you’re riding on trails against the wind, it feels incredibly cool. Just like the wind is combing through your hair. You do get “helmet hair” after taking off your helmet, though. But that’s normal.
You’ll be glad to know that the chin bar is detachable. For long climbs, you can remove the chin guard and use it as an open helmet. It’s a 2 in 1 basically. There are three sizes you can choose: S, M, and L. Plus, you’ll get so many color choices. We simply love this helmet right here! Buy it, and you’ll definitely love it!

Giro Chronicle MIPS MTB Helmet
We’re back looking at this cool open Giro MTB helmet. Although it’s not as light as the Giro Fixture, it’s very well-made. You’ll get a super deep POV plus visor. Although technically you can’t adjust this visor like those face guards on full-face helmets, you can try unscrewing the black dots and pull it up or down.
This helmet has 14 air vents, which is awesome. The inner Coolmax padding is very soft and comfortable. The outer shell is rock hard and made from reinforced polycarbonate. What we really love about this model is that there are so many sizes to choose from. It will definitely suit a wide range of riders.
Also, you can wear your goggles comfortably while wearing a helmet. The Roc Loc system also allows you to dial in tension that feels just right for your head. Overall, this is a fantastic selection at a decent price that guarantees to give you all-day comfort and safety on your most technical or challenging rides. It’s worth it!

Giro Hex MTB Helmet
Hex yeah, now we’re really talking! This impressive Hex MTB helmet is by far the lightest one on our list. Are you ready: it weighs only 11.2 ounces! Yes, ounces! The airflow on this one is amazing. There are 21 wind vents coupled with plush inner padding. It feels so comfortable. You’ve definitely got to try it out!
Featuring on this Hex is the unique time-tested Roc Loc 5 system. With this system, you can easily adjust the tightness of your helmet by turning the ratcheting dial wheel located at the back of the helmet. It’s super simple and smooth. Once you’ve tried, you may never go back to not having a Roc Loc dial on your helmet!
With Super Fit engineering, you can comfortably wear your Giro eyewear with your helmet without the worries of any risks or discomfort. The dual pods are thoughtfully designed to grasp the back and front of your head nicely and firmly. You know how important the brainstem and frontal lobe are for your performance.
We truly appreciate it that Giro thoroughly tested their helmets before releasing them to the market. This Hex right here can be your reliable partner for over 6,600 cycles. That’s around 3 years of continuous and even abusive use. We’re very impressed! Overall, this is just a fantastic helmet that’s so cheap compared to other models. The smallest one costs around $40. So, definitely check this out!
- Lightest helmet
- Well ventilated
- Time tested
- Lab tested
- Easy-to-use Roc Loc system
- Strong materials

Demon Podium Full Face Mountain Bike Helmet
The Demon is absolutely for you daredevils out there! It looks so sleek and the price is relatively cheap! Now, there are 13 airflow vents on this one. But unlike other models we’ve gone through, the vents on Demon Podium are partially covered with padding.
The special thing about these padding is that there are many tiny little holes on them. This makes ventilation an enjoyable experience. It’s a bit nicer, in our opinion, because you won’t get that feeling of strong wind “pounding” all over your head. It’s just more gentle.
This is a super cool helmet that has been CPSC certified. We think you’ll absolutely love the design. They have a black background with nice highlights on the chin guard. You can’t detach the chin guard like the Bell Super 3R helmet, though. But, the helmet comes in many sizes. You can even get one for your little kids. They have a super clear size chart on their website, too! For example, the XS size would fit a head circumference from 49 to 53 cm.
For a price from $80, we definitely want you to try this awesome helmet out! Thumbs up!
- CPSC certified
- 13 air vents
- Super cool looking
- Nice ventilation
- Many Sizes
- Reasonable price
- Strong materials
- Comfy padding
- Chin guard is not detachable
This is a super wow helmet on our list. Not only is it cheap, but its performance is also superb. What stands out most on this Team Obsidian helmet is its integrated ABS skeleton system. Simply, these are the pods (like those dual pods on Giro Hex) that grab onto your head firmly providing extra protection and shock absorption.
To adjust the tension of these skeleton frames, you just need to twist the knob (at the back of the helmet) horizontally or vertically. It’s super duper simple. We absolutely love it! There are 22 air vents on the helmet, which give a very good ventilating experience while riding. Basically, there are two sizes: S is for 54 – 57 cm and M/L is for 58 – 62 cm. There’s also a Quick Release buckle attached to the strap. That’s very convenient!
The S size helmet is super light: 0.6 lbs! The bigger one only weighs only 0.63 lbs! In any case, this is a lightweight helmet! If you don’t find your perfect fit, you’ll get your money back. No questions asked. All in all, this is a risk-free choice that has been tested and trusted by over 400 happy riders. You’ll have a safe experience wearing the helmet!

- Clear size chart
- Durable materials
- Strong protection
- Excellent customer service

- Only 2 color choices
Fox Metah Solids Mountain Helmet
Fox is another huge player in the helmet industry that we’ve got to introduce to you. This Fox Metah solid is actually motocross inspired. They have the most beautiful designs in our eyes. The helmet is also amazingly lightweight: 1.95 lbs!
There are 10 Big Bore air vents on the helmet. It allows your body heat to dissipate while drawing cool air in. Although 10 vents are fewer than other models’ number of vents, the size of the vents is considerably large. We’d say this is equivalent to 13 or 14 smaller-sized vents.
Fox has this great Varizorb system which gives you the ultimate protection. It’s kind of like MIPS. It’s a multi-density impact reduction system, to be exact. You can also adjust the retention with one hand. There’s also a visor that protects you from UV rays, glare, mud, or dust on the trails or along your ride.
We’re sold. We’re just sold at this point. This is a great helmet that will protect your head reliably and makes you look super cool wearing it! Definitely check it out!
- Beautiful designs
- Good ventilation
- Great protection system
- Visor to block out glare and dust
- Premium quality
- The helmet takes up quite a lot of space
The Ultimate Guide To Choosing Best Mountain Bike Helmets
Open vs Full Face Mountain Bike Helmet: Which one should you choose?
This is a hot debate that has been going on for years. You may have already had some ideas about the advantages and disadvantages of both types. For us, we’d go with an open helmet.
The advantages of an open helmet are that it’s much lighter. Still, it provides you with awesome protection for your skull. Also, it’s much cooler (as in temperature) wearing an open helmet. You may find chin guards too hot. They even make you sweat more on longer and hotter rides. Lastly, open helmers are usually cheaper than big, bulky full face ones.
A slight disadvantage of open helmets, however, is its visor. Usually, the visor on open helmets is not deep or adjustable. That’s why you may need to equip extra goggles to protect your eyes against dust or glare.
Full Face Helmets
On the other hand, full face helmets will give you full protection from your skull, eyes, to your chin. Some models go all the way down to the back and sides of your head. The visor on full-face helmets is great. You can easily adjust it however you want. The chin guard is there making sure you have your full number of teeth even if you crash. You’ll feel much safer wearing this type of helmet, especially if you’re young riders or beginners.
The disadvantage of full-face helmets, however, is that it’s too bulky and heavy. It can be a pain to carry with you during long trips. Also, it’s hot to wear the helmet for longer periods of time. The last point is that it’s also more expensive.
If you can’t choose between the two, we recommend getting a hybrid helmet. That is a 2-in-1 convertible helmet. One of the best choices is the Bell Super 3R. You can easily remove the chin guard and turn it into an open helmet for longer adventures! Super convenient!
Do you need a camera / GoPro mount on your helmet?
The main job of a helmet is to protect your head. However, because we only live once, some folks seriously do not want to miss the moments during great adventures. That’s why they need a camera or GoPro mount on their helmets to capture the best footages to share with their friends, families, or even their social media followers.
Some manufacturers understand this need and have the camera mount built right on the helmet. The best one on our list is the Bell Super 3R. It makes videotaping super easy while you’re conquering new heights with your bike.
Other models don’t have this feature, however. But, you can easily order a camera mount on Amazon and hook it on the helmet. The GoPro is expensive but the mount is not too expensive. So, you should definitely check them out if you need one.
Size guide: Which size would fit your head best?
We understand that there are so many sizes available that makes it overwhelming to choose the right helmet size at times. But keep this simple tip in mind, and you’ll be well on your way to choosing the perfect helmet for you.
Like measuring the waistline, you want to measure the widest part of your head. If a helmet fits the widest part of your head, the rest will fall into place nicely.
To measure your head circumference, place the measurement tape about 1.5 cm above your ears and measure all the way around your head. Get the double-sided tape that has both inches and centimeters so you don’t have to do all the conversions every time.
And, that’s basically it. If your head circumference is around 54 cm, you can get an S Team Obsidian helmet. If it’s 49 cm, get an XS Demon Podium. Remember to measure your kids’ head circumference frequently because they do grow up very fast. Don’t buy a helmet that’s bigger just because you think they’ll grow to fit it. Get the right fit right now!
You generally don’t have to worry about the lower part of your helmet (aka the chin straps on open helmet). That’s because chin straps are adjustable. You’ll also get tension dial at the back of the helmet to dial in the best tightness to fit your head.
How much is a good bike helmet?
The price range on the market today is around $50 to over $200. That also depends on the size and model you choose.
If your budget is around $50, you can check out the Giro Fixture or Giro Hex, Fox Metah, and Team Obsidian.
If your budget is around $100, check out Demon Podium, Troy Lee, and Giro Chronicle.
If you have over $200 to invest, see the Bell Super 3R.
1. Why do mountain bike helmets have visors?
Visors are there to protect your eyes from harmful UV rays, glare, rain, mud, or dust. All of which, could affect your performance and concentration while riding.
2. What is the best MTB helmet?
Our top picks are Giro Fixture, Troy Lee, Bell Super 3R, Team Obsidian, and Demon Podium. There are other great choices from Fox, too!
3. What is the safest mountain bike helmet?
Basically, all mountain bike helmets have MIPS and some are even CPSC certified. The safest ones you can choose are Bell Super 3R, Giro, Demon Podium, Fox, or Team Obsidian helmets.
4. How often should I get a new bike helmet?
That depends on the current condition of your helmet. If you recently crash it, we’d recommend getting another fully functional one. If there are very small scratches on the helmet but overall it still looks good, you can continue using it. Also, if you get one for your kids and they grow bigger, you should definitely get a new helmet to suit them perfectly.
Some helmets on the market today (like Giro Hex) can be used for up to 3 years. That’s around 3 round trips every day. If you find yourself using your bike and helmet heavily every day (e.g. like more than 1 hour daily), it would be a good idea to replace the helmet every one and a half year. This is to make sure that you have the ultimate protection every single time.
