Crafted from thick horsehide and dyed using kakishibu persimmon tannins, this jacket is designed not only to be worn, but to visibly evolve over time, developing depth, warmth, and individuality with every exposure to light and wear.
Initially appearing in a light khaki-beige tone, the jacket undergoes a dramatic transformation as the kakishibu oxidizes with sunlight. Over months and years, the color deepens into rich caramel and amber hues, much like fine wine aging naturally. This living surface makes each jacket entirely unique, shaped by the environment and habits of its wearer. Faithful to its WWII inspiration, the silhouette is short and boxy, creating a striking balance when paired with high-rise denim and heavy boots.
The leather:
This jacket is made from 1.5mm thick horsehide, chosen for its strength, grain definition, and ability to hold complex dyes. The leather is treated with kakishibu, a traditional Japanese dye made from fermented persimmon tannins that has been used for centuries in clothing, armor, and utilitarian goods.
The full tanning and dyeing process takes nearly two years to complete. Kakishibu is known for its photosensitivity – also referred to as Taiyo-zome (sun-dye) – meaning areas exposed to sunlight gradually darken and become more vibrant. Compared to standard vegetable-tanned leather, this kakishibu horsehide ages faster and more dramatically, developing a deep, glowing patina that cannot be replicated artificially.
Beyond its visual beauty, kakishibu also naturally enhances durability and resistance, making the leather tougher over time while remaining breathable and organic in feel.
Construction:
The KB140T is constructed as a faithful homage to the original WWII Type I…
