Criteria Used For The Evaluation

Weight

Lightweight helmets are always excellent to have when you plan on doing longer bike rides, but they do tend to cost more as a benefit. So, how lightweight you really need your helmet to be is something you’ll have to consider along with the comfort level. Most lightweight helmets still bring you excellent levels of protection and durability, so there really is no sacrifice or trade-off here when looking for your perfect mountain biking helmet. The typical standard for purchasing this type of helmet is that the more lightweight your helmet is, the higher the price of the helmet. Most all-mountain helmets come with everything you need and weigh in the 13-ounce range, which is a weight many riders feel is still comfortable for their rides without costing them much more in price. However, if you still feel you need something lighter than that for comfort value, then be prepared to pay a bit more for your helmet.

Airflow and Ventilation

Purchasing a helmet with an effective ventilation system is something most mountain bikers require when they are out on the trails. On today’s market, there are many styles and options of helmets that bring you high-quality ventilation systems that will help cool your head for the duration of your trip. When you’re considering the ventilation system on a helmet, there are a few things you need to think about. First, some helmets have more holes and vents on them, which sounds like they’ll boost ventilation, but this isn’t always the case. Good ventilation really comes from the overall quality and design of the helmet, as well as how these vents work and where the vents are located on the helmet. Helmets offering good ventilation systems usually have a good retention and padding system inside the helmet that doesn’t interrupt airflow, while other manufacturers may not consider ventilation with padding and thus decrease airflow in the helmet. So, you need to find a helmet that’s interior padding is also made for better airflow, and when you find this, you know you’ll have a helmet with an excellent ventilation system.

Fit and Size

When you’re looking around for your mountain biking helmet, probably the most important thing you want to investigate before purchasing anything is the fit of the helmet. If the helmet is too tight or constrictive, you can get headaches from it easily, and that’s something you certainly don’t want to deal with when riding on the trails. If the helmet is too large, on the other hand, it’ll flop uncomfortably on your head and offer you less protective benefits in case you fall or crash. So, when you’re looking to purchase your next bike riding helmet, you should focus on a helmet that has an adjustable fitting system so the helmet is easy to accommodate to your head. Many of these fit systems are easy-to-adjust, and can cinch to the correct size of your head. One of the best adjustment systems on the market today is the Roc Loc fit system, which is so easy-to-use you can adjust it with one hand, while it also locks securely on your head. All you have to do with this type of fit system is lock it on your head. Most of Giro’s helmets come with the Roc Loc fit system, while other manufacturers offer something comparable to it.

The size of the helmet is another feature you’ll have to look into as well. Many helmets come in a wide variety of sizes to better fit the head of the person wearing the helmet. Some baser helmets come as one-size-fits-all type helmets, which works well only for those thinking about doing casual mountain bike riding. If you need a helmet for more serious terrain or something that’s versatile, then you’ll need to search around for a helmet that comes in multiple sizes. Helmets made in different sizes do typically cost more, but they also offer better comfort, fit, and overall protection. So if you want something versatile, look at helmets that offer different sizes.

Helmets for Women

The helmets listed on our guide above are mostly unisex, and can be work by either men or women. However, for some women, this might not offer what they need, and they might choose to opt for women’s-specific designed helmets with different sizes, colors, and other features. However, most women’s-specific helmets don’t vary all that much from the unisex featured helmets we’ve provided on the list and don’t really increase the amount of comfort or protection the everyday female rider might think she’s getting by buying a helmet made just for women. So, while it’s something many women might want to consider, they are just as safe purchasing unisex helmets. Really, the choice is up to you with this feature.

Interior Comfort and Design

While making sure you’ve got a helmet that fits correctly is probably the most important comfort feature you’ll need to consider, the second most important feature you’ll want to look into when purchasing your next bike riding helmet is interior padding, comfort, and design. Typically, the better the cushioning and the more comfortable the fit, the more the helmet will cost. For bike riders that worry about the helmet smelling, rubbing, or creating any type of skin irritation, then investing in a higher-priced helmet will probably be the better option. If you can find a helmet that gives a good fit system and comfortable interior padding options, you may not even feel the helmet as you are riding on the trails. Plus, the more expensive padding systems in certain helmets help with sweat absorption while you are out on the trail. Of course, you’ll be paying a bit more for this benefit, but if you have sensitive skin or can’t stand the sweat odor that can come out of your helmet as you ride, then it’s probably worth buying a helmet with that level of protection. If you do decide to purchase a helmet with better interior padding options, beware of washing the helmet in your regular washer, and consider washing it by hand. Some manufacturers advertise the ability to throw your helmet into your washer, but to make sure you don’t damage or destroy the lining, hand washing, especially on a more expensive helmet, is almost always the way to go.

Helmet Mold Construction

Almost all mountain biking helmets on the market today advertise their in-mold technology designs. Typically, these designs are made up of some thin shell (typically polycarbonate) and include an EPS foam liner that’s been molder together. With this type of helmet mold construction, you’ll get a combined piece that’s made to make the helmet more lightweight, and also allow for ventilation holes that increase the airflow on the helmet while still allowing for the helmet to work as a single unit should you incur any crashes or impact while out on the trails.

As far as helmet mold construction is concerned, there are a few manufacturers that offer different things with their designs. For instance, POC uses the Armamid fibers in the core of the helmet, the same material that is used to create bullet proof jackets. This brings extra durability and protection to the wearer. Smith also does something a little different, with their Aerocore layer of Koroyd under the shell. So, really, increased levels of protection will cost you more, but as long as your helmet has good in-mold construction design standards, your head will be protected in case of impact.

Safety and MIPS

Many of the helmets on our list have Multi-directional Impact Protection System (MIPS) designs that come along with the helmets. This technology usually increases the cost of the helmet, but you’re getting something good if you are willing to pay for the benefits.  MIPS helmets bring you better head protection in case of crashes, and are also lower in friction, meaning the technology reduces rubbing and skin irritation. With the MIPS technology, you’ll get one additional removable thin plastic layer you can use when you wish. MIPS is supposed to help reduce impact to more sensitive areas of your head if you crash.

As far as current safety standards for helmets on the market, all we can really gage from that is whether or not a helmet passes that test, but not much else. Every helmet we have here does pass current safety standards, and not all of them have MIPS technology. While the effectiveness of MIPS technology is still currently under review, it does have research backing up its ability to better protect your head upon impact. So, while you don’t need to buy a helmet with MIPS technology if you don’t want to buy a more expensive helmet, you do get better safety if you are willing to pay for the upgrade.

FAQs

Q: What are some features I should consider when selecting my mountain bike helmet?

There are a few features you’ll want to consider when selecting your mountain bike helmet that we haven’t covered here yet. Those features are visors, goggles, and cameras. Whether or not you need a helmet that includes these features is up to you, and we’ll cover some of the benefits below.

  • Visors. Many different kinds of mountain bike helmets offer the additional visor feature. For many riders spending long hours in the sun, having the added feature of a visor not only helps protect their eyes from the sun, but also protects the face from low-hanging branches they might ride into quickly while on the trail. Most of the visors come in different shapes and styles, and the different brands offer different features. Some of the helmets covered above offer visors, but their types do vary. For instance, the Troy Lee A2 Helmet has a wide, short type visor, while the Giro Chronicle Helmet has a narrow and long visor. Other manufacturers offer larger, moto-inspired type visors, which are becoming more standard on the helmet market today for bike riders. Besides the size of the visor, you also need to look at the visor’s adjustability if you want a helmet that comes with a visor. Adjustable visors are great because you can easily move them when you no longer need them; for instance, if they obstruct your vision. They also help you keep your goggles easily on your helmet when you are not using your goggles. Even if your helmet features an adjustable visor, not all types of visors adjust as well or as easily as others. Also, not all of these helmets will give you room for your goggles. The Troy Lee A2 lets you easily slide your visor up and down, but doesn’t give you enough space for goggles. However, whether you want a visor at all, and what type of visor you pick, is really all up to you. Not all bike riders feel they need visors, so the choice is up to the mountain bike rider.
  • Goggles. Some helmets offer features that allow you to wear just about any type of goggles you want, while other helmets offer fits that don’t always permit the rider to wear goggles. Many mountain bike riders prefer wearing goggles so they get better protection from dirt flying into their eyes, but again, whether or not a bike rider wears goggles is usually up to the bike rider. So, if you do want to wear goggles with your helmet, look for a helmet that keeps those goggle straps in place. Some helmets that fit goggles offer a long list of features and benefits that can cost you more, and that you don’t really need as long as the goggles stay on the helmet. Some helmet features that can help accommodate your goggles better are highly adjustable visors and retainer straps, and really, that’s all you need for a helmet that can accommodate your goggles easily. If you opt for a visor and know you will wear goggles, you want to make sure that visor can adjust easily so you can slip your goggles easily on your forehead when you might not want to use your goggles. Also, helmets with retainer straps to hold goggles on the helmet are also better for those riders wearing goggles. Also, don’t just assume that an all-mountain helmet will bring you all of these features—that’s a mistake. You do need to always look closely at the helmet’s visor and retainer straps if you are purchasing a helmet that lets you more easily wear your goggles.
  • Camera Mounts. Another unique, but not always necessary feature, you might want to consider when buying a helmet is a camera mount system. If you like shooting film of your adventures, you can get a great first-person view by directly attaching an action camera into a helmet that comes with a mount system. Most helmets offering this feature easily accommodate a camera you can slip into your helmet. Some higher-priced helmets come with built-in action camera mounts that make it easier to get the camera angle you want as you’re riding, allowing you to ditch the use of a sticky mount. However, some riders are just fine without this feature and if you don’t want to fork out the cash for this, you can always buy an action camera later and place it on the handlebars of your bike.

Q: When should I replace my helmet?

Deciding when you need a new helmet can sometimes be difficult to determine. Remember, most helmets you purchase do come with a shelf life, so you don’t want to use an old helmet that might not protect you as well if it’s been used for a long period of time, outdated, and past its shelf life. When taking a look at your helmet, determine whether or not you see the foam cracking, if you see wear on either the outer shell or inner lining, and if anything looks questionable to you. If you look at any of these features and feel uncomfortable, it’s time to purchase a new helmet.

Most manufacturers give their helmets a shelf life of anything between three and eight years. However, this doesn’t always determine the wear and tear on the helmet, which can increase if you ride more often than the average person. For avid mountain bike riders, you’ll probably need to replace your helmet more often. But, that is again something that the person with the helmet needs to determine.

If you crash while wearing a helmet, then you’ll need to see if the foam inside is damaged. If it is, then you know you need a new helmet because the helmet won’t offer the same type of protection after the initial crash.

Final Thoughts

While the type of helmet you purchase for your outdoor mountain biking adventures can vary depending on what you need, you do want to consider a decent helmet that will protect your head from impact. The helmets provided on this list all offer excellent head protection, and some come with extra features that make them cost more.

The fit is the most important thing to consider when you are buying your helmet, so make sure you select something that fits you well. After that, you have a variety of features and benefits to choose from depending on what you need in your helmet.
