Fox Racing in KOROYD represent a completely new chest and back protector that combines lightness, exceptional ventilation and advanced impact protection. Fox Airframe protection is not just another protector – it is a redefinition of how modern protection for motocross and MTB should look. It is designed for those who want more than just safety – they want freedom of movement, all-day comfort and uncompromising protection.
Main advantages of Airframe protector
- KOROYD technology with expandable structure – the material naturally adapts to body movement, which means more freedom and less discomfort.
- Light, low-profile design – the protector fits snugly to your body without bulky plates, so you barely feel it under your shirt.
- Exceptional ventilation – open-cell structure allows up to 20% more airflow compared to comparable protection.
- Adjustable fit – adjustable straps, belt and additional removable protections (key fob, upper chest area).
- CE-certified protection – back part (EN 1621-2 Level 1) and chest part (prEN 1621-3 Level 1) provide tested safety.
Innovative protection that moves with you
During development Airframe protector the emphasis was on movement. KOROYD technology with an expandable structure allows the material to expand in all directions when stretched and to contract evenly when compressed.
This means that the protector fits every movement and does not create pressure points or discomfort. Fox and Koroyd have thus created protection that does not restrict, but supports the body's natural movement.
Why is KOROYD important?
KOROYD It is an engineering material made of fine vertical "tubes" in a "honeycomb" - comb pattern that breaks upon impact and distributes energy over a wide area. The advantages of this solution compared to traditional hardshell inserts are twofold: high energy absorption upon impact and exceptional breathability, as the open profile allows air flow.
Fox has positioned KOROYD inserts on both the chest and back portions of the protector, thereby offering comprehensive protection with minimal weight.
Ventilation without comparison
The open-cell KOROYD material design ensures maximum ventilation. While many helmets trap heat, Airframe allows constant airflow – even at high intensity and hot days on the track. This means less overheating and more energy for riding.
Shaping and Ergonomics
Airframe is designed as a low-profile layer between you and impacts from rocks, mud and dirt flying off the trail. It's not a conventional heavy hardshell construction, but rather a combination of lightweight TPE frame and KOROYD inserts that conform to your body and allow for a range of motion. The shoulder straps are adjustable, the hip belt features quick-release buckles, the inner lining is stretchy and comfortable, and removable collarbone pads provide an additional protective layer when you want it.

Field test: first impressions
At the Fox Raceway media day, we had the opportunity to test the Airframe under real conditions. The temperature was nearly 40 °C, ideal for testing ventilation. The result? The Airframe was incredibly comfortable and breathable, to the point that it was almost unnoticeable under the jersey. Many riders who typically skip chest protection admitted that the Airframe convinced them because of its lightness and mobility.
"At times I forgot I was even wearing it. The protector didn't hinder my movement and I had the feeling that I was protected without sacrificing comfort." one of the test drivers said.
Advantages noticed by testers:
- Excellent ventilation even in heat
- Loose and adjustable fit
- Simple setup and quick fastening
- Option to remove certain protective parts
- Fewer pressure points compared to classic shields
