We use high-quality genuine leather, specifically horsehide. As you wear it, the deep, unique wrinkles of the horsehide will become more pronounced and three-dimensional, aging like a vintage rider's jacket. The vegetable-tanned leather, especially the tea-core horsehide, is a particularly attractive point for fashion enthusiasts and rider's jacket aficionados. Being the finest horsehide, it fits well and, as a classic style, is not affected by trends. It can be used in various situations, such as for town use, riding a motorcycle, or driving an open car. Please enjoy the texture of genuine leather that conforms to your body the more you wear it. Simple yet elegant, it's a versatile item that matches a wide range of styles. It combines a tough and stylish appearance with high functionality.
