A new era of turnouts with Fire-Dex

AeroFlex ™ by Fire-Dex marks a groundbreaking leap in firefighter comfort and safety

In the line of duty, your biggest danger is heat stress.

As your body’s core temperature rises, you lose the ability to concentrate, make sound decisions, and think critically.

Today, heat stress contributes to over half of reported line of duty deaths.

When physical exertion leads to accumulation of heat and sweat, your body naturally cools down by allowing sweat to evaporate.

Without an escape route for the sweat vapor, it stays trapped against your body.

Fire-Dex has discovered that traditional gear fails to cool you down where you need it the most.

That’s why they developed AeroFlex™, a new era of turnout gear that incorporates material science and design features that supercharge the breathability of your garment while significantly reducing the risk of heat stress and cardiac-related issues.

Designed with VaporLite™ Panels and AeroVent™ Technology, AeroFlex™ supports core body temperature regulation, encouraging airflow to keep your body cool and comfortable without compromising the protection you need!

The peak of technical brilliance

Fire-Dex uses a breathable and proprietary 3-layer composite system that targets the areas of your body where heat becomes most encapsulated, the side seams, armpits, inner thighs, and behind the knees.

VaporLite™ Panels allow sweat to evaporate more efficiently than any garment available to the fire service today and are built exclusively with Fire-Dex’s TECGEN71 outer shell, a CoreCXP™ 1-layer thermal liner, and your choice of moisture barrier.

TECGEN71 is the only outer shell that can be paired with a single-layer thermal liner thanks to its exceptional breathability and thermal protection, achieving industry- leading Resistance to Evaporative Heat Loss (Ret) and Total Heat Loss (THL) performance.

Choose any composite for the rest of the garment and allow these panels to cool the core.

The first of its kind, AeroVent™ Technology utilizes a one-way street ventilation design that operates in conjunction with the pressure differential between the outer environment and the microclimate inside your gear, allowing sweat vapor to escape without letting heat or carcinogens inside.

AeroVent™ Technology enables you to better regulate your core body temperature, reducing the risk of heat stress and other cardiac-related issues.

Particulate-blocking technology in the vents act as a barrier against potentially harmful carcinogens.

“I am amazed at how cool it felt,” said Battalion Chief Chad Christenson of the L.A. County Fire Department following a long-term AeroFlex™ wear trial.

“I tried on several occasions to saturate myself with as much convective and radiant heat as possible, then when I moved around, I actually started to cool off.

“This has never happened in any other set of gear I have worn. The technology is amazing.”

Dynamic movement

The vents lie within the VaporLite™ Panels, with two positioned along the armpits and two placed on the inner thighs, facilitating airflow and promoting optimal cooling where it matters most.

By promoting airflow through dynamic movement, AeroVent™ Technology generates a constant cooling sensation.

As the wearer becomes more active, increased air circulation within the garment results in a heightened cooling experience.

“The difference was felt while active,” said Engineer Bradley Smith of the Long Beach Fire Department.

“While moving, there was a noticeable difference among the participants who all described the gear as cooler.

“This is the first garment I have tested that addresses the overheating of the firefighters by reducing heat stress.”  

AeroFlex™ is a state-of-the-art ensemble that not only symbolizes next-gen technology but also underscores Fire-Dex’s commitment to ensuring that everyday heroes can confront challenges with resilience and, most importantly, return home safely.
