Zero-G Helmet Upgrade Kit

Zero-G upgrade kit

Advanced Padding Materials

The fabric used in the construction of the Zero-G Helmet Upgrade Kit is 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.

over similar product, even during extended mission duration.

Improved Stability

properties. When operating temperature is high, the liner will remain
cooler. When temperature is cool, liner will help retain the heat in.

Liners and ear seals are enhanced with permanent anti- odor and antimicrobial

Modular Design
Our products will fit any US or foreign flight helmet. Upgrade now to
bring new life to your old helmet.

Zero-G Helmet Comfort Liner

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 head shape. These materials are covered in a heat and
moisture wicking anti-microbial fabric.

Comfort Liner Sizing

The Alpha Helmet Comfort Liner is available in the following thicknesses (all
Alpha Liners are 13” in length): 1/4”, 3/8”, 1/2” and 5/8”. The SPH Helmet
Comfort Liner is available in 1engths of 16” and 17” and the following
thicknesses: 1/4”, 3/8”, 1/2” and 5/8”.

Zero-G Ear Seals

Pro Flight Gear Ear Seals will fit many existing aviation communications
headsets. The laminate structure provides optimum comfort, noise attenuation,
and maximum side impact protection. The sonic interior wall allows stray noise
to penetrate the interior wall and then dissipate into the ear seal’s sound
deadening material. This layer also provides heat and moisture wicking
properties, keeping the wearer cool and dry. These products will not generate
hot spots commonly associated with this type of life support equipment. The
ear seals will conform around objects such as eyeglass frames and not create

3/4″ and 1/2″ ear seals are available for Alpha Flight Helmets.
