Reviews - The Best Helmets for Mountain Biking

Smith Venture MIPS

Specs
  • Vents: 20
  • Weight: 11 oz.
  • Visor: Yes
Features
  • Adjustable Fit
  • Proprietary Venting System Aids In Preventing Fogging On Sunglasses

BEST FOR: ALL-MOUNTAIN RIDING

What began in 1965 to create better snow goggles has morphed into a global company that creates engineered sunglasses, goggles, and yes, helmets. The Venture contains the MIPS layer that helps to reduce rotational motion of the brain during impact and lessening the severity of the crash. 

Created using in-mold construction (where the outer shell is bonded to the foam in a mold utilizing steam and pressure), the result is a lightweight and durable helmet for the full spectrum of mountain biking. Using a proprietary adjustable fit system, the helmet will remain secure over any terrain. The twenty vents not only create an aerodynamic effect, but also perpetuate cooling as you ride. The helmet also has an integrated visor to provide additional protection from the sun.

  • Has MIPS (Multi-Directional Impact Protection System)
  • Proprietary Closure System Allows For One-Handed Adjustment

BEST FOR: CATCHING THE DOWNHILL ACTION ON CAMERA

Outside of mountain biking circles, you may not be familiar with the Bontrager name. However, you probably do recognize the name Trek Bicycle Corporation. Trek bought Bontrager and the brand continues to produce its quality line of tires, helmets, and other gear.

Also featuring the MIPS safety layer, the Rally also sports the BOA closure system which allows the rider to dial-in the fit of the helmet. One of the cool features we like on this helmet is the integrated mount that will allow you to attach an action camera or a Bontrager light accessory for night riding. Bontrager also offers a crash replacement guarantee which will replace your helmet free of charge if you crash within the first year of purchasing the helmet.

POC Octal X SPIN

Specs
  • Vents: 18
  • Weight: 10 oz.
  • Visor: No
Features
  • Eye Garage Keeps Your Sunglasses In Place
  • Embedded Recco Reflector Enhances Radio Signals From Search-And-Rescue Recco Detectors
  • Proprietary Impact Protection System (SPIN)

BEST FOR: CROSS-COUNTRY (XC)

Less than twenty years old, POC is a Swedish company that creates products that help create a safer experience for active people in sports that can sustain head and body injuries like skiing and cycling.

This is the only helmet in this guide that doesn’t feature a visor as this helmet is designed for the XC (cross-country) rider and a visor isn’t as much of a necessity as the need for a lightweight model with ample ventilation. POC helmets feature the brand’s proprietary SPIN rotational impact protection system which is designed to reduce the amount of force transmitted to the head and brain during a crash. The eye garage is a cool feature that helps to keep your sunglasses in place. Only the POC helmets in this guide feature the embedded RECCO reflectors which, when used in conjunction with RECCO detectors, can help locate lost or injured riders.

Features
  • Adjustable Visor
  • Proprietary Impact Protection System (SPIN)
  • Integrated Goggles Clip

BEST FOR: DOWNHILL RIDING

Founded in 2005, the Swedish brand POC got its beginning addressing ski racing safety. That same mission and technology has been expanded to provide safety measures for other gravity fueled sports, including mountain biking. 

The Tectal Race also features the proprietary SPIN rotational impact system. The SPIN pads allow the helmet to move with the head and therefore reduce the force of impact. Paired with an adjustable visor, the Tectal Race features a goggles clip for securing the eyewear on race day or just for intense riding. Like the other POC helmet, this model also features an embedded RECCO reflector for assisting in the location of injured or lost riders.

  • Optimized Venting Without Exposing Most Vulnerable Areas Of The Head

BEST FOR: DOWNHILL AND CROSS-COUNTRY

Harkening back to 1988, Sweet Protection got its start in Norway and has been creating protective gear for adventure sports ever since. What began as a school paper created the basis of the Sweet Protection mantra: Stronger, Lighter, Better.

The Bushwhacker II is created using a five-piece in-mold plastic shell fused with shock absorbing foam to create a highly protective casing for your cranium. The helmet is secured utilizing a proprietary turn-dial mechanism. It’s one of the lightest helmets in this guide and even though it only has thirteen vents, the helmet is designed to efficiently channel the air to keep your head cool even under pressure. The foam comfort pads inside the helmet are wrapped in a hypoallergenic and moisture-wicking fabric.

Bell Sixer MIPS

Founded in 1985, Giro is a United States based cycling and snowsports company. Their offerings include eyewear, apparel, and of course, helmets. The Chronicle features the MIPS rotational impact safety layer, so you can feel confident wearing this helmet on even the steepest of descents. 

The helmet is secured in place by a proprietary dial-in system that can be adjusted with one hand. The fourteen vents channel the air throughout the helmet with ease. The Chronicle is designed to be goggle compatible and the integrated visor can be lifted, allowing for placement of goggles, and then lowered before heading downhill. The plush Coolmax padding allows for extra moisture wicking in addition to the extra comfort qualities.

Oakley DRT5

Perhaps one of the most recognized names in the outdoor sunglass arena and founded in 1975, Oakley offers more in their lineup than just sun protection. In addition to their iconic sunglasses, the brand also creates a line of products ranging from goggles, apparel, helmets, and even footwear. 

The DRT5 was created in collaboration with 3X world champion downhill racer, Greg Minnaer. It has an integrated eyewear dock to secure your shades and keep them accessible. The one unique feature on this helmet that sets it apart from others in this guide is the BOA fit system that features a 360-degree design that ensures an exact and perfect fit every time.

 

THINGS TO CONSIDER BEFORE BUYING A MOUNTAIN BIKE HELMET

TYPE

When choosing a bike helmet, it’s important to consider the type of riding you plan to do. Helmets designed for road cycling don’t typically provide enough protection for the terrain associated with mountain biking. The three main types of mountain biking are cross-country (XC), all-mountain, and downhill.

Cross-Country (XC)

Cross-country riding involves covering a lot of ground with limited technical terrain. This can involve lots of uphill riding where adequate ventilation is key to surviving the climb. The POC Octal X SPIN is a great choice for XC riding.

All-Mountain

All-mountain riding involves more technical downhill terrain and therefore should include more protection than what the average XC or road helmet can provide. All-mountain helmets often provide more coverage around the temples, the back, and the sides of the head. They often include more padding as well. The Smith Venture MIPS and Troy Lee Designs A1 MIPS are good examples of all-mountain helmets.

Downhill

Downhill riding is found in most bike parks and the bulk of the riding involves careening down rocky and technical terrain. We didn’t include any of the full face mask models in this guide as they can be super hot if any pedaling is involved. The POC Tectal Race SPIN is an excellent option that is on our list, as it also includes a goggle clip for securing your eyewear while racing or aggressive riding.

 

HELMET SIZE AND FIT

No two heads are alike. Therefore, there is no better way to ensure proper fit than trying on a multitude of helmets to find the one that fits your lid the best. With that said, helmets come in different sizes and there is no one size fits all when it comes to finding the right one for your unique head shape. In preparation, you can know the size of your head prior to searching manufacturers.

How to Measure Your Head for a Helmet

First, find a flexible measuring tape (the kind that a seamstress and tailor would use) and measure the circumference around your head just above your ears and roughly one-inch above your eyebrows. The measurement should include the largest part of your head. Make sure to record your results in both inches and centimeters (or convert). This number should fall within the range of one of the helmet sizes.

Fit is crucial to ensuring that your helmet performs at its maximum potential. If the helmet is too tight, you’ll be prone to seeking a resolution throughout your entire ride. If it’s too loose, you will possibly subject yourself to the helmet not working properly in the event of an accident. A helmet should fit snug without being too restrictive. Most premium helmets come with a form of adjustment dial on the back which allows you to dial-in the fit and most can be adjusted with or without gloves.

 

VENTILATION

Ventilation is crucial whether you are pounding out the miles on the uphill or shooting down the slopes at a bike park. It’s easy to work up a sweat even riding the fast downhills and having an option to allow for heat dispersal is paramount. As you can tell from the list above, there is a wide range of options ranging from thirteen to twenty-six vents. Optimal ventilation isn’t as basic as looking at the number of vents, though it’s a good place to start. Some helmets might have a lower number of vents but more adequately move air from the front to the back.

 

SAFETY

MIPS (Multi-directional Impact Protection System) is found on many of the helmets in this guide like the Giro Chronicle and the Bontrager Rally. Other proprietary alternatives to MIPS include SPIN (both POC helmets in this guide) and those found in the Sweet Protection and Shred helmets.

In addition to adding a steeper price tag to the cost of the helmet, the advantage of these safety systems is that they add a layer of protection. With MIPS, a low-friction layer is added to the helmet that allows the head to move 10-15mm within the helmet in all directions. This is important during an angled impact as it reduces the rotational motion to the brain.

 

COST

If your budget is limited, cut corners elsewhere and splurge in the helmet category. You only have one brain and spending a little extra to ensure you survive a potentially high impact crash is worth the investment. There are options that are relatively inexpensive, but you need to ask yourself if those models are going to offer you the best level of protection.

 

 

FEATURES EXPLAINED

MIPS

MIPS stands for Multi-directional Impact Protection System. For more information, read the paragraph above about safety.

RECCO REFLECTOR

This advanced rescue technology involves the use of a RECCO detector. It’s advantageous in the event of an avalanche or when someone becomes lost in the outdoors. The RECCO detector emits a directional radar signal and the reflector replies with an echo. Rescuers are then able to zero in on the potential victim. These reflectors are available in apparel as well as both POC helmets in this guide.

BOA

BOA is a performance fit system that allows users to dial-in for a precision fit. To loosen, you just have to pull up on the dial. To engage, push in and dial to the desired resistance and it will hold indefinitely. This system is used in a multitude of products including footwear, helmets, and medical applications.

IN-MOLD CONSTRUCTION

Known by other names like in-molded, molded in the shell, and other proprietary names, the technique is relatively the same. A thin outer piece of plastic is placed in a mold and foam is injected. Under pressure and steam, the foam expands and bonds with the plastic, creating the helmet shape.

VISOR

A lot of mountain bike helmets now feature either a fixed or adjustable visor. This addition can provide additional protection from the sun or another layer of protection from rogue limbs and branches while riding down the trails.
