Smooth, elegant full-tannin leather with a hand-finished grain surface.
Leather made from domestic steer hides that has been full-tannin tanned in Japan.
This is an unfinished leather dyed solely with dye, characterized by a firm, substantial tannic quality and a matte, smooth appearance.
The grain surface is hand-ironed to flatten it, resulting in a smoother, more refined finish.
Finished with a specially formulated oil, this series offers a rich, supple texture that allows you to truly experience the authentic character of the leather.

LEATHER MODEL ID: KAI 2
The KAI 2 is a double rider's jacket featuring reconstructed details, based on the KAI model which was inspired by 1960s vintage rider's jackets.

By designing the front overlap to be narrower, the bulkiness characteristic of double rider jackets is reduced, creating a sharp front profile.
The chest pocket found on the "KAI" model has been removed, resulting in a simpler front design. In place of the hem belt loops, adjuster belts featuring STRUM's original buckles have been added to both sides.
In addition, this product incorporates natural-colored leather made from domestic steer hides that have undergone full vegetable tanning in Japan.
By incorporating natural-colored accents—such as on the underside of the collar, pocket openings, cuffs, hem panels, and adjuster belts—a contrast is created against the black-based rider's jacket, serving as a design highlight.

The zipper is manufactured by the Italian company Raccagni. Its smooth operation and exceptional durability reflect the exquisite craftsmanship characteristic of Raccagni, a company with a long history of producing high-quality zippers.
Metal components that add a touch of elegant luster to the rugged aesthetic harmonize with the texture of the leather, elevating the level of perfection down to the finest detail.
Except for the front zipper, all fasteners are concealed to keep the design as simple as possible.

The back is crafted from a single, luxurious piece of fabric. Gussets are incorporated at the underarms to enhance range of motion.
For the sleeve lining, we use a polyester material to ensure smooth movement when putting the garment on, while the body lining is made of high-quality cotton satin—a fabric typically used for outer layers—to ensure durability.
