1. A baseball jacket, regardless of its design style or materials, is trendy or has a variety of extensions. However, its main feature is that the sleeves are different colors from the top and are mostly made of different materials. The chest is printed with text or patterns, and there are almost no lapels. The collar often has two or three rolled edges that are different colors from the collar (some have cuffs), and the pockets are mostly located near the hands on both sides.
2. Flight jacket, with sleeves of the same color and material as the top, and a preference for colors such as green, gray, blue, black, or leather primary colors commonly used in military uniforms. The collar is not limited to whether it has a lapel or not, and the common lining material to lapel is light colored wool. It is mostly designed with multiple pockets, not only on both sides, but sometimes on both sides of the chest and cuffs. The elastic bands on both sides of the collar, cuffs, and hem are mostly different colors from the main body of the garment. The surface materials commonly include nylon canvas and leather, which are their general characteristics.
