We have encountered and analyzed a variety of military jackets in the past. From official government-issued items to test samples from rare eras, we have come across jackets that defy conventional wisdom and thinking. We have been working day and night on replicating these jackets to meet fans’ expectation. As the times changed, the military reviewed its equipment and improved and developed it. In particular, the colors of the jackets were specifieorces, and many of them were produced in colors that aimed to create camouflage effects. Normally, navy and khaki are regarded as the N-1’s standard colors, but the rare brown color was found to have been officially adopted to N-1 jacket.
