USAF Type
F-1B Extreme Cold Weather Flight Trousers - Used
The Type
F-1B Extreme Cold Weather Flight Trousers (officially designated as Trousers,
Extreme Cold Weather, Type F-1B) are high-altitude, sub-zero defense pants
engineered specifically for U.S. Air Force flight crews and static ground
personnel. Purpose-built to function at mean monthly temperatures below 14°F
(-10°C), these high-waisted overpants act as an impenetrable insulation
system. They are designed to be layered comfortably over standard uniform
trousers, offering maximum defense against bitter winds and biting frost
without causing structural bulk.
Constructed
with a wind-resistant cotton and nylon heavy-duty Oxford outer shell,
the F-1B is stuffed with a thick, high-loft polyester batting insulation
that effectively captures and seals in passive body heat. Built to a strict
military layout (MIL-T-6284), these pants are detailed with dual-angle
utility pockets, integrated suspender button anchors, and a uniquely tailored
high-back rise to protect the kidneys and lower spine from drafting wind.
This specific
National Stock Number is custom-patterned for a Size 38 Waist. Because
these are designed to be worn over pre-existing clothing layers (similar to a
pair of fishing waders), they are built with an inherent oversize margin to
track perfectly over your baseline clothing profile.
In Used
military surplus condition, these trousers carry authentic character from
airbase or hangar deployment. All items are professionally inspected to
guarantee full operational serviceability. While they will display standard
signs of vintage field service—such as light cosmetic fabric scuffs, minor
storage discoloration, or faint thinning of the external water-repellent
finish—all heavy-duty zippers, pocket enclosures, and seam lines remain fully
intact and field-ready.
