We have utilized "Japan Calf Leather" from Hokkaido, which is finished by one of the leading tanners in the country and adheres to a commitment to being purely domestic—a material we continue to use in our leatherwear as a staple. Its firm, supple texture feels excellent in the hand and is easy to handle. While calfskin is known for its flexibility, it is also characterized by the formation of unique, large, wavy, and three-dimensional wrinkles. The base material is dyed beautifully in its raw state before the product is constructed. Afterward, the finished product is washed and tumbled to create distressed marks and shrinkage, resulting in a textured, impactful appearance. It is finished using the same process as our leatherwear made with Japan Calf Leather.

The main storage space, equipped with an interior pocket, features a simple structure that maximizes capacity, making it a highly functional backpack. The double-zipper design allows for easy opening and closing. Furthermore, a dedicated sleeve pocket for a laptop has been provided on the back, ensuring both security and smart storage. The front of the bag incorporates design details inspired by a double rider's jacket. It features four zippers—representative of a rider's jacket—and a coin pocket, all of which are functional as exterior pockets. The design allows for organized storage, carrying, and easy access to personal items, making it highly specialized in functionality. The substantial gusset not only provides ample storage but also makes it convenient to load and unload items. Based on a relatively large-sized backpack capable of carrying a significant amount, this design incorporates a rider's jacket aesthetic and product processing to create a strong presence. However, by using calf leather as the material, it maintains a soft impression. As the bag is used, the original stiffness of the leather will transform into an exceptionally soft, comfortable texture, deepening into an aged look that feels refined and not overly flashy. All sections are fully lined.
