The fabric and materials used in the construction of these products are designed to draw perspiration away from the cranium and cool the wearer through the evaporation process. Independent testing has shown the combination of the ear seals and helmet liner significantly improved impact protection to standard liners and ear seals. These products have been engineered to provide pain-free flying for pilots and aircrew to ensure the focus is on the primary mission, not the fit or stability of the flight helmet.

Independent and DoD testing have shown that the core material of these products deliver superior blunt impact performance over OEM product.
The Pro Flight Gear upgrade kit provides significantly improved comfort over similar product, even during extended mission duration.
Provides increased stability, most notably when helmet is equipped with additional ancillary equipment such as night vision goggles.
The internal fabric of our helmet liner provides thermal regulating properties. When operating temperature is high, the liner will remain cooler. When temperature is cool, liner will help retain the heat in.


Our products will fit any US or foreign flight helmet. Upgrade now to bring new life to your old helmet.
A drop in replacement liner to upgrade the pressure displacement and comfort of your existing flight helmet and enhance the overall fit. The suspension system (padding) is a rate and temperature sensitive material that conforms to the wearer’s unique cranium shape. These materials are covered in a heat and moisture wicking anti-microbial fabric.
