Among the jeans offered by 45R in 2024, these are the slimmest unisex denim. The material used is the signature Futatabi 6.5, a 14 oz fabric known for its crisp texture and durable body, woven on vintage shuttle looms from the 1950s that slowly craft the denim to perfection.

The deep Ai Indigo color, applied through multiple dyeing processes, is designed to change subtly over time, fading to a misty purple shade that retains its elegance wash after wash. A unique discharge print featuring '有 - Aru (meaning "exist") adorns the natural indigo fabric at the back waist patch, complemented by detailed sashiko stitching throughout, embodying the pinnacle of Japanese craftsmanship. These jeans promise enduring style and quality, reflecting the essence 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.
