People have always seemed concerned about the weight comparison and the burly look of these helmets. To be fair and honest, a full-face mountain bike may not be the lightest compared to the open-face helmets, but it indeed gives you the best protection of a full face.

The protection safeguard and weight compatibility have made these helmets more popular at cross country races. So, if everything is set up to this point, let’s research some of the best and most OK mountain bike full-face helmets.

Buying Guide of Full Face MTB Helmet:

There are a lot of factors behind a safe and satisfactory mountain bike helmet. Over the years, technological improvements have made helmets lighter and safer than ever. Better still, you have to look for a few things to get your mind focused on a particular type of helmet. Let’s get forward to clarify basic requirements to buy a perfect full-face MTB helmet for you.

Protection assurance process of  Full Face MTB Helmet

An outer layer and inner layer made of eps foam comprise a mountain bike helmet. The polycarbonate layer protects the inner layer with eps foam to skid in the event of a crash rather than catching or whipping your neck around. During a collision, the eps foam absorbs the force of impact by crushing or breaking its structure. The design crashing process protects the brain from concussion.

Ensuring a Proper Fit with Full Face MTB Helmet

Ensuring proper fit is a rule of thumb while considering a new helmet. It’s a bit tough to acquire the perfect size online, but the user manual information will help you out with each corner’s size chart and measurement. We often find incidents like a particular model fitting specific people as almost every head shape differs from each other.

Trying a helmet before buying is the key to avoid size mismatching. Or, if you are using online platforms, find one with a perfect return policy. Sometimes, e-commerce websites use a solid return policy to exchange products without any extra cost.

Leatt DBX 4.0 is an Amazing piece of lightweight helmet that rules all the factors associated with a mountain bike helmet with a solid feel around your head.

Weight and Ventilation Check

850 grams of weight for a mountain bike full-face helmet is not the best weight consideration, but the balanced ventilation is comparably quite excellent in its own right. The smaller vents allow less airflow than the Fox Proframe or Troy Lee Designs Stage, but the construction is just perfect for your rough ride.

Safety Check

Leatt’s turbine technology makes the Leatt DBX 4.0 a shiny, comfortable, lightweight full-face helmet that is well known for better protection and comfort. In terms of safety and security, it is one of the best picks. Padded stripes and magnetic Fidlock ensure a perfectly comfortable fit around your head.

  •  Interior Padding

The interior padding and the overall construction provide a full-on downhill helmet feel. The EPO soft foam allows complete protection for the head while ensuring maximum absorption of low G impacts. In an extension to that, more rigid EPS foam takes care of the rest. In terms of eye protection, the Leatt DBX 4.0 has the drawback of not featuring an adjustable visor.

  • Turbine Helmet Technology

Leatt DBX 4.0 comes with the latest Turbine Technology. Flexible rotating pads perfectly placed throughout DBX makes it rotate without exerting the rotational force on the head. Leatt made it pretty clear that Turbine tech reduces 30% of the head impact at concussion level and deducts 40% of the rotational acceleration to the head and brain.

 

Pros of Leatt DBX 4.0:

  • Padded stripes
  • Magnetic Fidlock
  • Dual-layer of EPS and EPO foam
  • Turbine Tech

The 24 vents have ensured a great ventilation system which includes a massive cutout in the chin bar to maintain the proper airflow.

Safety Check

To avoid G impacts, the Fox Proframe comes with a dual-density EPS foam liner. In addition to that, the MIPS anti-rotational insert allows superior comfort while riding. You might not feel that the foam is the best of the class, but they are not skimpy either.

The Fox Proframe does not come up with a complex construction or various mix of technology. Still, the innovative combination of the material and design structure makes it a cost-effective and lightweight full-face helmet.

A comfortable design is the main priority of this helmet which has no mouth guard for the chin bar, but from my point of view, that will not be a deal-breaker for most.

Eye Protection 

Fox Proframe MIPS comes with a fixed visor leaving enough space to adjust extra goggles for your precious eye. Unlike the TLD stage straps, this helmet features a magnetic Fidlock buckle attached to well-padded straps that ensures proper comfort to your ears.

Moreover, Fox Proframe may not have many unique features up its sleeve. Still, the lightweight, protective design with a proper ventilation system is quite unmatched among other full-face mountain bike helmets, which is the main reason to become one of our best picks.

Moreover, the ventilation system and the overall weight consideration makes it a great choice compared to the other available helmet in the market.

The TLD stage features softer EPP foam in the interior case. Along with that, the combination of a more rigid EPS liner and softer EPP ensures necessary protection for your brain against any concussions in case of low G impacts.

Additionally, the MIPS insert is a unique feature that makes TLD stage a high-end full-face mountain bike helmet. Unlike Leatt’s turbine technology, the MIPS insert does not come with any weight penalty, ensuring a lightweight structure for this helmet with better protection.

No pad in the stripes might feel a bit annoying on your ears on longer rides, but the magnetic flock will ensure a comfortable fit.

Eye Protection

Eye protection is the best part of the TLD stage helmets as it comes with an adjustable visor, unlike the Proframe or Leatt DBX 4.0. The adjustable bill allows you to stash a pair of goggles under for a long summer ride or even a hot mountain climb. This visor adjustment steps up the level of the TLD stage while adding almost 0 weight to the whole structure.
