No matter how much inspiration and materials are mined from history, there are always items that are neglected in the world of military uniforms. The Submarine Soldier N-1 Jacket is one of them. Even in professional military books, it is rarely mentioned because it is not an official jacket issued, but Civilian Jacket purchased spontaneously.
Since submariners spend a lot of time underwater, their personal attire and appearance are not strictly regulated. Practicality comes first. In contrast to the official deck jacket, the submarine jacket is not covered by wool from the waist to make it easier to use the deck suspenders, which are more flexible and warm enough.
The fur collar of the submarine jacket is similar to the shape of the fur collar of the early flight jacket (M422). It is a fleece collar with flaps and a windbreak buckle. The white pure wool inside is thick and heavy to cope with the harsh environment.
