This unisex straight-cut jean features a comfortable rise and a fit that snugs nicely around the hips, crafted from 45R's signature 14 oz Futatabi 6.5 fabric. Known for its crisp texture and robust body, the fabric is woven on vintage shuttle looms from the 1950s that meticulously craft each strand of denim.

The jeans feature a natural indigo-dyed fabric at the back waist patch with the discharge print '有 - Aru (meaning "exist") and are intricately detailed with sashiko stitching throughout. The deep Ai Indigo color, developed through multiple dyeing processes, evolves with time, fading into a misty purple hue that maintains its elegance through extensive wear.

Additionally, the Sumi Ai Indigo process enhances these jeans by dyeing over the Ai Indigo with ink extracted from soot. This layering technique allows the top black layer to age gracefully, gradually revealing the underlying natural blue, merging into a beautifully deep, aged blue effect. These jeans are designed to last, reflecting the timeless appeal of Ai denim.

How Does Natural 藍 Ai Indigo Denim Age?

Top: Regular Indigo Dye | Bottom: Natural 藍 Ai Indigo Dye

Both pairs are 45R denim, aged over five years, each showcasing indigo blue's beauty. Regular indigo dye presents the "Nakaziro" effect, where the warp's fading indigo exposes the weft's white yarns over time, transitioning the color to a bluish white. In contrast, Natural Ai Indigo dye fades slowly, maintaining a deep indigo hue even with prolonged wear.

This unique aging, known as "Nakaziro," highlights the charm of rope-dyed indigo. As the warp threads lighten, the weft's white threads become visible.

100% natural Ai Indigo differs from regular indigo in that its dye particles are exceptionally fine, allowing the dye to penetrate deeply into the fibers. As a result, even as the denim ages, the weft threads that emerge also display the indigo color, continuously creating a deep blue hue.

Leaves of Persicaria tinctoria, the source of natural Ai Indigo dye

Fermenting and resting the leaves repeatedly to develop the dye

Natural Ai Indigo dye, over a year in the making.

Our natural Ai Indigo is derived from the Persicaria tinctoria plant, grown in Japan. The process involves planting the seeds, nurturing the plants, and harvesting them—followed by fermentation—a journey that takes between one to one and a half years to produce the dye itself.
