Best Mountain Bike Helmets Review And Guides 2020

best mountain bike helmet

If you do not have time for the details, here are our top picks for mountain bike helmets:

A helmet, while easily overlooked, is one of the most important components of mountain bike gear. The technology in your helmet can make a huge difference in how protected you are during a crash

In general, mountain bikers ride in two different types of helmet: a full face or a half-shell.  

Full-face helmets are used for downhill and some Enduro riding. They have a hard chin guard which sits in front of your face and offers added protection during a crash. 

The second type of helmet is a half-shell. This helmet sits on top of your head and wraps around the sides and back to varying degrees.  

More protective mountain bike helmets will have a longer back which can protect the back of your head or lower sides to protect the area around your ears.  

Generally, full-face helmets or helmets with larger coverage are safer options. However, this added material also adds weight and minimizes ventilation.  

The key to finding the right helmet is to pick the helmet that is comfortable enough for you to wear while still providing the protection you need for the type of riding your participating in.  

Helmet Technology

Technology around helmets has grown drastically in recent years. There is a huge range of systems which all work to protect you during a crash.  

MIPS- MIPS, or Multi-directional Impact Protection Systems are found in many new helmets. This system utilizes an inner plastic liner/basket that sits between your head and the foam of the helmet and has the ability to move and reduce the rotational force in some crashes. 

EPS- EPS, or Expanded polystyrene is a crushable foam is intended to soften the blow of being crushed or landed. Most helmets have EPS foam combined with a hard shell to increase protection.  

Varizorb- Varizorb is a type of EPS foam that is injected into the mold from two different directions, creating pyramids of interlocking foam that help dissipate the energy from an impact.  

Spherical Technology – Spherical technology utilizes a ball-and-socket design, capitalizing on allowing the outer shell of the helmet to rotate around the inner liner when you crash. This system prevents some of the damaging rotational forces of a crash.  

SERT- SERT, or Seven Energy Reduction Technology works to reduce impact from rotational forces, oblique impacts, and low-G direct impacts through a combination of flexible cubes inside the helmet shell.  

Shell Materials 

Helmet shells are typically made of polycarbonate. They help protect your head during a crash by providing a hard shell to cover the foam layer.  

In-mold polycarbonate – In-mold polycarbonate means the EPS foam is attached to the polycarbonate shell. This method allows the helmet to be lighter and more protective.  

Aerocore- Aerocore technology utilizes hexagonal patterns like a honeycomb to improve temperature regulation, airflow, and impact resistance.

How do I know which helmet is best for me? 

Picking the best helmet is highly dependent on which terrain you plan to ride. If you will spend most of your time at a downhill park, you should consider a full-face helmet for maximum protection.  

If you plan to spend your time in a mix of downhill and cross-country style riding, perhaps the Giro Switchblade is a good option due to its versatility. 

If you plan to stick to cross-country riding, a smaller and lighter helmet will suffice.  

How important is airflow? 

Depending where you live, the ventilation of a helmet can make a huge difference. In warm or humid environments, maximizing airflow can make be a game changer while out on the trails.  

Further, full face helmets can be very warm and finding an option with maximum ventilation may be helpful in hot environments.  

How long can I use the same helmet? 

Helmets are intended to be used until they are crashed on or break. The best helmet technology is intended to be crashed on only one time.  

Unfortunately, this means if you have a hard crash and hit your head, it is critical to check for any dents, cracks, or damage. If your helmet has any visible damage points, it is compromised and will not protect you as well if you crash a second time.  

The advanced helmet technology can make a huge difference in preventing head injuries. Even though you may need to replace your helmet after a crash, it many ways, it is a small price to pay to ensure you’re staying as safe as possible while riding.  

What should I consider when it comes to eyewear? 

In general, riders who climb uphill use sunglasses and riders who only ride downhill use goggles.  

In order to stay cool and comfortable while riding, glasses can protect your eyes while still providing ample airflow.  

Downhill riders may opt for goggles because they are less concerned about ventilation and may choose to have more protection from using downhill goggles.  

What do I need to know about visors? 

Visors can be a helpful component of a helmet in order to provide shade from the sun. However, visors can also increase the rotational damage of a crash.  

Many helmets utilize flexible or easily movable visors to decrease this risk.  

How can I keep my helmet in good condition? 

When cleaning a helmet, use a mild soap to clean the liner and shell. Visit https://maidwhiz.com/. You can use some water to wipe off dirt or bugs from the shell of the helmet but do not submerge the helmet for long periods of time. 

Scrubbing the chinstraps on your helmet with mild soap and water can help keep them soft and clean.  

Some riders will simply take their helmet in the shower and rinse it with soap and water, then leave it out to dry. 

It is also possible to take the pads out and either hand wash them or throw them in the laundry to remove the sweat and grime.  

When storing your helmet, avoid keeping it in high heat locations as this can melt the glue that holds it all together. It is also important to keep your helmet away from chemicals such as sprays and solvents which can break down the glue as well or damage the EPS foam.  

How do I know if my helmet fits? 

Your helmet should fit snugly on your head and the straps should go around either side of your ears.  

The front of the helmet should sit most of the way down your forehead. Ensuring a proper fit is an important component of making sure your helmet can take care of you when you crash.  

Best Pick Product 

In my opinion, the best helmet for downhill riding is the Fox Proframe. This helmet offers superior safety combined with ventilation and a lightweight construction.  

If you plan to ride downhill or Enduro trails, the Proframe looks great and will keep you safe while out on the trails.  

In terms of trail riding, the Oakley DRT5 is an awesome combination of safety, function, and appearance. The lower back will protect your head and the sunglasses holders will make sure you keep your eyewear with you.  

This helmet is a great option for a rider looking to ride trails with a focus on downhill.  

Cross country helmets often resemble road helmets, and the Smith Network is a great helmet for riding with speed and safety. This helmet looks great and provides a unique airflow system in a lightweight and safe design.  

Regardless of which helmet you choose, remember it can only keep you safe when you’re wearing it correctly and ensuring you have taken proper care of it. Enjoy the trails!
