ALPHA Eagle Flight Helmet Zero-G

Zero-G Helmet Upgrade Kit

The fabric and materials used in the construction of these products are designed to draw perspiration away from the head 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.
