Designated 'Type D-1 Mechanics Shearling Jacket', this model came into service with the Air Corp in the mid 1930's.
It would seem a rather lavish material to be making a mechanics jacket out of, but the D-1 like all clothing and equipment issued to US servicemen was typical of the motto 'only the best will do'.
Similar to the shearling flight clothing the D-1 was made and issued as a two-piece suit - its companion bottom half being the B-1 trousers.
Its unfussy simple design, made from 1/4 inch fleece depth sheepskin, with two practical zippered front pockets, made it very popular not only with groundcrew, but aircrew as well.
The sheepskin material itself is of North American origin. There are many breeds of sheep throughout the world, each having their own wool characteristic, so it is essential that we use a fleece derived from the same breed that was used originally so as to ensure complete authenticity.
The Eastman D-1 is of course finished out with every other detail that is necessary to make this garment 100% authentic.
Available in sizes: XS - XL.
