With this blog I’ll share my top picks for the best female mountain bike helmets.
Let me start by saying there really is no such thing as a female mountain bike helmet. Apart from the fact that on average a woman’s head might have a smaller circumference, there’s no anatomical difference between a man and a woman, which necessitates a specific helmet.
It doesn’t mean that helmet manufacturers do not specify certain helmets as a women’s version. Giro has a “Women’s Series”, yet specifically states:
“The Women’s Series is a diverse collection of helmet styles, fits and prices tailored to the demands of female riders. While the level of detail and range of colors is unique within the Women’s Series helmets, they do not feature a unique “women’s fit.” That’s because there is no anatomic difference between women and men’s heads except for the average skull diameter measurement.
I’ve looked at the sizes and technology used in Giro’s women’s lineup vs. unisex helmets, and have found no difference. There isn’t any difference in sizes offered, and there’s no women-specific technology or anything used in the Women’s series.
So with that out of the way let’s head over to the list of the best female mountain bike helmets, or rather best mountain bike helmets.
At the end of the article I’ve created a table overview of all the helmets for easy comparison. The “rating” refers to the Virginia Tech rating; a lower number is better.
Bluegrass Rogue Core MIPS






The Bluegrass Rogue Core MIPS is a distinctive-looking open face mountain bike helmet for trail and enduro riding with quite a name.
Its unique visor is a non-indexed fully adjustable one that leaves enough room for large goggles to be fitted underneath. Sunglasses are supposed to be stored in the visor instead of eyewear ports. It remains to be seen if this works for all types of glasses out there.
Each helmet manufacturer uses fancy names for their fit system, so with this helmet you get the Safe-T system. The name notwithstanding, it’s the same we see with other premium helmets, offering indexed customizability both vertical and horizontal.
The helmet has the average weight for a mountain bike helmet of 350 grams, and you can achieve a snug fit without any pressure points.
The Rogue Core has one of the best crash ratings on the market and I feel it’s because of lack of marketing that this helmet doesn’t really get the attention it deserves.
- Distinctive looks, great fit, and excellent crash protection for a trail helmet
- None
Fox Racing Dropframe Pro






The design of the Fox Racing Dropframe Pro is certainly unique, and a hit-or-miss design-wise depending on the person you speak to.
Design arguments aside, what you can’t deny is the added amount of crash protection you get with this helmet, there’s simply more of it.
The shell is made from a mix of thermoplastic, polycarbonate, and polyamide instead of your regular polycarbonate. The liner is a dual-density EPS for added energy absorption versus a regular EPS liner.
The helmet wraps around the ears, providing more coverage without getting in the way of your field of vision. And it also comes with the MIPS crash technology, something almost every high-end helmet currently has.
At 460 grams it’s about a hundred grams heavier than your standard open face mountain bike helmet, but that added weight is something you won’t notice while riding.
One thing to keep in mind is that the visor is fixed into place, which might impair your vision on very steep descends.
Because the helmet covers a much greater area, Fox decided to ditch the adjustment wheel normally used to create the desired fit. Instead Fox achieves a comfortable fit by providing a padding fit kit with two different sets of padding. Together with the Fidlock buckle it does a great job in keeping the helmet in place.
In terms of heat management, more coverage also means more heat buildup. If you’re using this helmet for a lot of ascending, it’s noticeably warmer. On the other hand, slow climbing is not really the intended use of this helmet.
The Fox Racing Dropframe Pro is a perfect choice for those who’re seeking for more protection, without wanting to ride with a full face helmet. And it fulfills this role outstandingly, offering better crash protection than any other standard open face mountain bike helmet.
- Offering more protection over your standard open face helmet, without neeing to go for a full face one.
- The design, the fixed visor, heat buildup
Fox Racing Speedframe Pro






The Fox Racing Speedframe is the same helmet as the Pro version in everything but a small number of features.
The Speedframe Pro is one of the best helmets in terms of safety, and the standard Speedframe inherits many of its safety features except for the multi-density EPS liner.
The helmet is known for having an excellent fit, and you can fit a pair of goggles underneath the 3-point adjustable visor, as well as stash your glasses.
A good fit without pressure points, and a huge number strategically placed vents funneling air into and over your scalp keeps the heat buildup at bay. The air flow is especially noticeable when you pick up speed.
To keep the price down when compared to the Pro version, there’s a cheaper liner and the Fidlock snap buckle is missing from the straps, in an otherwise similar 360 degrees fit system.
It’s a great-looking mountain bike helmet, available in many colors and 3 sizes to choose from.
- One of the safest mountain bike helmets, in lots of different color variations.
- None
Giro Merit Spherical






The Giro Merit Spherical offers superb crash protection in a fantastic open face mountain bike helmet.
There are multiple crash technologies ensuring this helmet sits at the top of the range in terms of protecting. As do many other helmets it offers MIPS technology. The Merit uses MIPS Air which is the lightest variant.
Furthermore it offers Spherical technology, commonly referred to as a ball-and-socket setup where the inside of the helmet can move independent from its outer shell. A dual-density EPS liner is the last piece of tech to ensure maximum crash protection.
The entire package is still very light at 360 grams. Other great features are the bolt-on adjustable visor and the multi-point Roc Loc adjustment system.
The only downside I can think of is that you have to pay a lot of money for all that tech.
- One of the best open face mountain bike helmets, period.
- Very expensive
Giro Tyrant Spherical






The Giro Tyrant Spherical is Giro’s single offering of a mountain bike helmet with ear protection. The brand consistently scores high rates in crash tests and this helmet is no exception.
Besides the now standard MIPS technology, it has a reinforced polycarbonate to keep the helmet structural integrity intact in case of an impact. The helmet also features dual-density EPS foam, to increase the energy absorption characteristics.
Its shape also means that besides added coverage you get added weight. The 600 grams of this helmet means it’s the heaviest open-faced helmet I know.
In terms of design the helmet obviously distinguishes itself from your average half shell mountain bike helmet. It also has a much cleaner look, especially when you go for an all black one.
Since the helmet covers a larger area of your head it’s meant for those either seeking added protection over your standard half shell, or more ventilated version of a full-face helmet.
- The go-to compromise when you don't want to go for a full-face helmet.
- It's both heavier and warmer than a standard half-shell. The Fox Racing Dropframe has a better rating
Giro Women's Merit Spherical






The Giro Women’s Merit Spherical is, as the name implies, exactly the same as the standard Merit, yet offers a range of colors Giro calls the “women’s series”.
As they state themselves on the sales page, there’s no anatomical difference between women and men’s heads.
- Offers the exact same outstanding features of the Merit Spherical.
- Very expensive
MET Terranova MIPS






The MET Terranova MIPS is a great-looking trail helmet with a premium-quality finish.
Although sometimes noted as “lightweight” it isn’t, weighing 355 grams for a size M. That’s 5 grams above average for an open face mountain bike helmet.
At such a weight the helmet sits comfortably when correctly adjusted with the Safe-T Duo system. If that name sounds somewhat familiar, it’s because the Bluegrass Rogue uses a similar system you can adjust both vertically and horizontally using an indexed dial.
There’s an optional gel padding kit for sweat wicking and an LED you can buy. Not including these means the price is kept low enough to be a mid-tier helmet with an excellent crash protection rating.
- Good-looking mid-tier helmet with a core focus on crash protection
- Padding might saturate easily
Sweet Protection Trailblazer MIPS






The Sweet Protection Trailblazer MIPS has one of the best Virginia Tech crash test ratings.
It’s the only helmet I know of that offers a polycarbonate shell made up of multiple pieces with variable thickness. And it seems to improve its impact resistance.
Naturally for a helmet with the premium category, you get MIPS technology as well to reduce and dissipate rotational impact energy.
To get the right fit the helmet offers both vertical and horizontal adjustment, with two sets of padding with different thickness. The vertical adjuster sits at the back, which means adjusting it lowers the back part of the helmet.
It’s extended coverage means it runs a little hotter than your average road bike helmet you might use for XC and light trail riding. But the weight of 325 grams is still light enough to make you forget it’s there while riding and setup correctly.
The helmet now includes an adjustable visor which let’s you easily fit glasses underneath it.
- Excels in the most important area of protecting your head from injury. And it's not even the most expensive.
- None
Troy Lee Designs A2






The Troy Lee Designs A2 is one of the most affordable, high quality, open-faced mountain bike helmets worth your money.
It offers superb comfort and fit, with an anti-bacterial X-Static Pure Silver padding. The padding sits within a dual-density EPS liner. The polycarbonate shell wraps around the edges to further protect the rather delicate EPS.
The decade-old design has been updated to feature the MIPS technology. Safety is further enhanced with the bolt-on breakaway visor, and 3-point fit system.
Part of the popularity of the A2 can be attributed to the comfort it provides. Both with the excellent fit and its ability to keep your head cool when you try and get the most out of your ride. 2 vents on the side extend far into the front. Together with elongated vents on top they suck in cool air, which can exit through a number of vents located at the back.
It’s a great looking helmet, available in many colors, with a perfect track record in crash protection, for a price below many of the top-of-the-line offerings from its competitors. An unbeatable proposition when it comes to mountain bike helmets.
- Best-in-class safety for a reasonable price when compared to the competition
- None
Troy Lee Designs A3






The Troy Lee Designs A3 is literally the bigger brother of the A2, offering more coverage in basically the same package.
The A2 is one of the best helmets on the market, so it’s no surprise the A3 scores just as well. and does so with a helmet that extends lower at the back of your head.
Offering MIPS technology dual-density EPS foam, and the overall excellent fit with an additional liner included in the package.
The antimicrobial resistant liner covers the entire inside of the helmet and provides an extremely comfortable experience that makes you forget you’re wearing it. Something the Troy Lee helmets are known for. A handy Fidlock buckle can be opened one handed wearing gloves.
The visor is 3-way adjustable. I actually prefer such a ratcheted system. And when pushed upwards it leaves more than enough room if you like wearing goggles.
The ventilation setup is different from the A2. I don’t know why they’ve done this, since there’s absolutely nothing wrong with the air flow of the A2. Luckily the amount of ventilation is just as good in keeping you cool.
As a flagship product it’s very expensive indeed, and might prove to be too big a jump with the A2 being just as good and much cheaper. But if you want extra coverage in a well-designed, good-looking Troy Lee helmet, this is the one.
- Bigger coverage version of the already fantastic A2 helmet
- Increase in price might be a bridge too far
