1. Fly Racing Kinetic Thrive Dirt Bike Helmet — Best Product Overall

Key Features

  • DOT-approved
  • Dual-density EPS liner
  • A lightweight and durable polymer shell

  • Custom molded rubber trim

This high-quality model from Fly Racing is made of a polymer shell, which is great because the material is highly durable, lightweight, and reduces neck fatigue for off-road riders.

You’ve got a removable comfort liner and dual-density EPS liner (does a good job of reducing energy transfer in case of high-speed impacts). The helmet is also DOT-certified; so, it offers excellent protection.

What truly takes my breath away is the True Functional Ventilation (TFV) system, which helps keep you calm, cool, and comfortable. The innovatively made cheek cushioning absorbs sweat and offers extra comfort. You’ve got three shells as well as four EPS sizes to choose from; so, getting a precise fit for different head sizes and shapes will not be a problem.

What I don’t like; however, are the limited color and/or graphic options.

  • EPS impact absorption
  • Multiple air vents
  • Reinforced chin strap

This incredible product features an aggressive design that meets as well as exceeds DOT standards for impact absorption, peripheral vision, retention, and penetration.

The heavy-duty construction is made of an ABS shell, which is great because it is extremely rigid and strong, resilient with superior impact resistance, stable at extreme temperatures, and scratch-resistant. The interior is lined with multi-density EPS for maximum impact absorption during a crash. The liner is heavily padded, removable, and washable. Riders experience less dragging, thanks to the aerodynamic design.

You’ve got multiple air vents that make sure you stay cool, calm, and comfortable. The uniquely designed visor keeps the wind off your face to improve visibility, especially in chilly weather.

But the thing is, the available sizes tend to run large and some models appear cheaply made.

Promote the sense of responsibility when riding those dirty off-road tracks with this great headgear from Orthrus.

Key Features

  • Aerodynamic flow design
  • ABS shell
  • Quick-release buckle
  • High impact absorption liner
  • DOT safety standards

The helmet features an aerodynamic flow design, which is great because it reduces drag. The air vents are uniquely positioned to release oppressive heat when riding in a warmer climate. This allows you to feel calm and comfortable on those dusty off roads.

The heavy-duty shell is made of high-quality ABS material for superior strength and impact-resistance. The liner inside is plush, soft, removable, and washable and it fits snugly for added comfort. The adjustable visor enhances visibility and you can conveniently rotate the shield to cut-off the blinding sunlight. The adjustable quick-release buckle; on the other hand, makes chin strap adjustment super easy.

What I don’t like, however, are the limited color, graphics, and size options.


  • The inner padding is sweat-absorbent for added comfort

  • The quick-release buckle system makes it easy to put on

Whether you ride on the dirt or any other off-road track, this amazing model from O’Neal has the features you need for your next adventure.

Key Features

  • ABS polycarbonate shell
  • Integrated face shield
  • Air channeled comfort liner
  • Padded chin strap
  • Double-D safety lock

The Sierra II has a polycarbonate shell, which is great because it is exceptionally lightweight and tough. When combined with an EPS liner, the shell provides remarkable impact resistance. The comfort liner is moisture-wicking for added comfort during long rides.

It comes with an adjustable visor for protecting you against strong winds and damaging sunlight. What I genuinely appreciate about Sierra II is the integrated face shield, which helps protect your face from twigs, dust, bugs, and other airborne objects.

What I don’t like about Sierra II, however, is that some sizes tend to run small.

You’ve got several vents, including exhaust, channel, and intake vents for improving airflow and comfort.

How to Determine the Correct Helmet Size

Dirt bike helmets are available in different sizes. But you have to know to determine the correct helmet size for your head to avoid guesswork.

The most suitable measuring tool is a seamstress tape measure. Alternatively, you could use a cord or an elastic string. The best spot for measuring your head circumference is on your forehead just above your eyebrows.

Make sure the tape measure goes around the widest point at the back of your head and it should go directly above your ears. The tape measure should fit snugly and not too tight around your head. Once you have that measurement you want to match it up with the manufacturer sizing chart on the product page. I say this because different manufacturers have different sizing charts. So, you want to make sure that you are using the chart that is associated with the model you are planning to buy.

Even after this is said and done, some models still tend to run a little bit smaller or a little bit larger. This is a known issue, so, make sure you are as precise as possible with your size selection.

Does Head Shape Affect Sizing and Fit?

Yes, and there are three main types of head shapes, oval, neutral, and round.

For an oval head shape, I am simply referring to the view you would get from the top-down. An oval head tends to be longer front to back than it is side to side. A neutral head shape or an intermediate oval tends to be longer front to back than it is side to side. A round head shape; on the other hand, is going to be about the same length from front to back as it is side to side. You can look for your ideal head shape from the manufacturer’s product page.

Does Customization Improve Fit?

Even with the right head shape and head size measurement, you can never be certain that you will get a perfect fit along the jawline. This is where many dirt bikers are going to be different and that is why customization is important.

The best dirt bike helmet will have removable padding for superior customization. This is important if you want to get the most out of the safety features of the helmet. A snug fit all the way around is important for off-road adventures.

Special Features to Look for in a Dirt Bike Helmet

Once you have selected your preferred brand and helmet size, consider special features that will make the helmet more comfortable.

Construction and Comfort Attributes

Choose a dirt bike helmet that comes with an aggressive construction with advanced features for guaranteed protection and comfort. The model you choose should be streamlined to reduce drag and noise. It must be well-ventilated for air intake and exhaust. Premium padding on the inside helps keep the helmet fitting snugly and comfortable. A heavy-duty chin strap; on the other hand, makes sure the helmet stays intact during a crash for enhanced protection. 

Minimum Safety Standards

When you buy a dirt bike helmet, you may just assume that it is going to protect your head because you trust the brand that you just bought. In which case you may never actually pay attention to the little sticker on the inside of the helmet or the box.

It tells you what safety standards it conforms to. The sticker means the headgear meets the safety test standards of the US Department of Transportation (DOT) and/or the Snell Memorial Foundation. Generally speaking even the cheapest headgear protection from reputable brands will meet the ideal safety standards. In some cases, a more expensive helmet may not be necessarily safer. 

Each safety standard organization has rigid procedures for testing the following:

  • Peripheral Vision: The dirt bike helmet you choose must provide a minimum side vision of one hundred and five degrees to each side. Most bikers’ usable peripheral vision is only about ninety degrees to each side.
  • Retention: The chin straps’ ability to remain fastened without breaking or stretching. Models with a well-secured strapping system improve head protection in case of a crash.
  • Impact and Penetration: Headgears that meet the minimum safety standards provide optimal impact protection. They normally come equipped with premium quality liner material throughout the chin bar for superior impact absorption. DOT and/or Snell-approved helmets can also withstand a blow from sharp objects.

Final Thoughts

The winner of this roundup is Fly Racing Kinetic Thrive Dirt Bike Helmet. What makes this model stand out is its target audience. It is a unisex design for both kids and adults. Apart from a dirt bike, you can use it with an off-road bike, snowmobile, mountain bike, UTV, and ATV. This high-quality product is offered in blue/white, matte dark grey/black, and white/black/gray.

Fly Racing is a brand well-known for its commitment to designing dirt bike helmets that provide superior protection and comfort. This model is DOT-certified, which is great because the brand meets the minimum safety standards for impact absorption, penetration, retention, and peripheral vision. You’ve also got a detailed sizing chart.
