This jacket has a tensile strength because of its outer nylon
skin.The softly worked up inner lining consists of NYLON and
isn´t lined with cotton wool but with a special kind of synthetic downy feather
-a heat insulating hollow fibre.
To avoid the
capillaries effects the hollow fibre is worked up with silicone.
lining isn´t simply put in but solidly sewn up (water-repellent but still washable).
Zipper in XL-size
& with right running closure
-often an attribute for "made in/for USA".
The knitted waistbands are worked up doubly with sturdy and steady elastic fibre.
The two inner & outer pockets (which can be shut) as well as an arm office complete
the classic jacket.
The first nylon flight
jacket was called B-15 and was designed in 1944, during the WWII.
The MA-1 was approximated
to the B-15, but manufactured without a collar.
Between 1949 and 1950
the MA-1 was issued to the AIR-FORCE pilots, the NAVY pilots and the flight crews.
Today, the government orders
CWU 45/P (Nomex) jackets for pilots and flight crews only.
Nowadays MA-1 jackets are
issued for the use of ground crew personnel only, such as security police, base
maintenance and line repair personnel.
