Phenix Fire Helmets has never treated comfort as simply a luxury. After 12 years on the job our founder, Retired Assistant Chief Ray Russell, started the company with the desire to create a lighter and more comfortable fire helmet. We continue that mission by listening to firefighters, asking for input and feedback, and taking that expertise into the design process of each helmet with laser focus on ergonomics, reduced weight, center balance, and fit. That philosophy was not mainstream back in 1972, but research since then has made this fact crystal clear: a comfortable helmet isn’t simply about feel – it allows the firefighter to perform their job safely with fewer pain points and frustrations. Today, we’ll dig into real world data to show seven reasons why comfort is ultimately about safety above all else.
In the content ahead, you’ll learn:
-
The role center balance plays in minimizing neck injury for firefighters
-
How helmet weight impacts head temperature and discomfort
-
The weight limit of a helmet before it presents a noticeable injury risk
-
What firefighters said when surveyed about the fit of their gear
-
How poor design can influence how hard a firefighter must work while on scene
-
The prevalence of neck and shoulder issues within the fire industry
-
The importance of range of motion to reduce neck strain
A poorly balanced helmet will increase neck fatigue
A study published in 2025 set out to learn how center of mass (COM) affected the neck muscles of firefighters wearing different fire helmets. During the study, firefighters performed various tasks under three conditions:
-
Wearing an American style helmet
-
Wearing a European style helmet
-
Wearing no helmet
The team studied neck angles, tracked endurance times, surveyed firefighters to solicit discomfort ratings, and collected EMG data from eight neck muscles. Their big takeaway? The lighter helmet did not produce less neck fatigue than the heavier helmet. While weight is a factor in overall comfort, the study found that the center of mass was more important in minimizing muscle fatigue in firefighters. A helmet whose design is high-profile shifts the center of mass in a manner that results in increased fatigue in neck muscles. The researchers suggest both prioritizing the helmet design’s COM as close to the head as possible and reducing overall weight.
While Phenix prides itself on having lightweight helmets in both metro and traditional styles, it is in the ergonomic low-profile design of our helmets that a firefighter finds relief from the top-heavy bobblehead feel often experienced with fire helmets historically.
Helmet design impacts neck movement
In the same study, researchers discovered that the lighter helmet’s inferior center of mass resulted in significant change in how the neck moves. When a helmet’s center of mass (COM) is higher on the head, the neck experiences both larger movements and faster movements during flexion (bending forward) and extension (bending backward). Researchers stressed the importance of a low-profile fire helmet design as a means to enhance range of motion in the neck and minimize the risk of neck injuries. A helmet with limited range of motion for the neck may also impact performance for the end user who must work harder to assess the scene and respond to various hazards.
By keeping our helmets properly balanced on the head, firefighters in Phenix helmets enjoy greater range of motion and reduced strain on the neck – a win-win for both comfort and function.
Firefighters already experience higher musculoskeletal-injury burden
A 2023 study, which collected data from 26 previous studies, found that nearly 1 in 2 firefighters experience some form of musculoskeletal disorder (MSDs). These injuries involve muscles, joints, bones, ligaments, and tendons. Of the 46% of firefighters who reported dealing with a MSD, here were the most common areas:
|
Area of the body |
Prevalence |
|
Lower Back |
34.32% |
|
Knee |
19.97% |
|
Shoulder |
18.68% |
|
Neck |
18.36% |
|
Upper Back |
10.15% |
|
Hands |
7.43% |
|
Feet |
6.66% |
Researchers recommend ergonomic improvements to reduce MSD risk. Ergonomics aren’t simply a “luxury” in an occupation that already places significant stress on the body – they are necessary interventions.
A Phenix helmet is only a small part of the total firefighter PPE ensemble, but working to reduce neck/shoulder problems in 37% of firefighters with MSD is no small accomplishment – that is 170,000 firefighters in the United States! With decades of firefighter experience here at Phenix, we understand the physical toll of the job and the importance of reducing unnecessary PPE burden.
PPE often impairs movement and mobility
Another study, this one from 2026, set out to understand how firefighter’s PPE affected their movement and performance during certain physical tasks. Pulling data gathered from 15 previous studies, researchers examined clothing, boots, helmets, gloves, and SCBA equipment. Their conclusion? PPE showed to impact several areas:
-
Dynamic balance – making it harder for firefighters to maintain their balance while in motion
-
Range of motion – restricted movement of the joints
-
Walking and gait – impairment of normal walking movement
-
Comfort/ease of movement – the feeling that gear is making their movement more difficult and/or less comfortable, even when they are not technically restricted by the PPE itself
The biggest takeaway: PPE designed without understanding movement, balance, and comfort negatively impacted the experience of firefighters on the job.
Surprisingly, standing balance and time to complete firefighting tasks were not affected significantly, likely a sign that firefighters are highly adaptable to the gear they use. Still, if firefighters have the capacity to adapt to their PPE, does that mean we should stop innovating? Why create unnecessary strain by forcing firefighters to adjust their gait, neck positioning, or movement patterns to compensate for poor equipment design?
When a firefighter is moving through a structure, they need to look up, look around corners, and work in awkward positions. In this environment, even small changes in how a helmet is sitting on their head can be a real problem functionally. At Phenix, we do not want a firefighter to compromise the way they move naturally while on scene. Our suspension systems are designed to be adjustable in three areas of the head: the overall circumference, the ride height, and the rear skull. When adjusted to the unique head size and shape of the wearer, a Phenix suspension properly fastened keeps the helmet in place for hours at a time.
Surveys reveal a strong desire for properly fitted PPE
A 2023 survey of 420 career and volunteer firefighters in the United States asked an important question: Does the way firefighting gear fit affect how easily you can move and do your job?
Unsurprisingly, 22% of firefighters felt that their gear did not fit properly. The problems ranged from their PPE being too loose, too bulky, too tight, or outdated because their body had changed over time since the gear had been issued to them. Of the hundreds surveyed, 99% considered proper fit to be at least very important for mobility. Comfortable gear, including helmets, doesn’t simply “feel nice”. PPE must fit the user properly to avoid interfering with their ability to perform a task.
The best feedback we often receive from First Due, TC-1, and TL-2 owners is this: “I often don’t even notice the helmet is on my head!”
Every gram on your head has a mechanical cost
So far, we’ve highlighted the importance of balance (center of mass), ergonomics, range of motion, and fit. The most obvious factor in what makes a fire helmet comfortable is, unsurprisingly, weight. Researchers have known about the importance of weight for decades. A study dating back to 1994 tested various helmets ranging between 3.2 and 6.6 pounds. The research team sought to understand how a helmet’s weight impacts the neck under strong acceleration. The findings were clear: heavier helmets increased three types of neck loading:
-
Compression – the forces that push down on the neck
-
Shear – the forces that slide the neck structures against each other
-
Rotation – the forces that twist the neck
When a helmet weighs 4.5 pounds or more, high acceleration forces substantially increase the risk of neck injury. While high acceleration forces are not part of everyday fire helmet use, the study shows that mechanical load represents a risk in certain unexpected environments. Weight and weight distribution are important ergonomic and safety considerations when designing a fire helmet.
Whether you are equipping your team with a modern metro style helmet or a traditional helmet, you can be confident knowing that Phenix helmets are designed with weight reduction in mind. Our First Due helmets can weigh as little as 2.5 pounds (40 oz), while our TC-1 and TL-2 helmets can weigh as little as 3.44 lbs (55 oz).
A lighter, better-designed helmet measurably reduces heat on the head
Lastly, a 2014 study assessed whether helmets (and other gear) changed how physically demanding or uncomfortable a firefighter felt in hot conditions. Three types of gear were tested:
-
American
-
Japanese
-
European
Subjects were placed in 90-degree Fahrenheit weather with 60% humidity to perform exercises and had the following measurements taken:
-
Heart rate
-
Oxygen usage
-
Perspiration
-
Core body temperature
-
Skin temperature
-
Head and leg temperature
-
Discomfort ratings
The most notable finding was that lighter helmets and lighter boots were associated with lower temperatures in the head and leg areas, making participants feel less discomfort. A helmet that was 1 pound lighter than the others did more than just reduce total load on the user – it made the head area feel cooler and the external hot environment more bearable.
Whether you put on a First Due in the scorching dry heat of the Mojave Desert or a TL-2 in the humid, sticky South, a lighter helmet can go a long way in reducing the discomfort of the harsh elements.
At Phenix, we’ve spent decades on the forefront of fire helmet safety, including being strong advocates for comfortable products. If you are interested in learning more about our history, explore our past blog content for additional insights from Phenix.
