The Big John “Yoshidenim” Green Label Wild Duck Jeans represent a thoughtful fusion of Japanese craftsmanship, sustainability, and innovative textile development. Developed as part of Big John’s eco-conscious “Green Label” line, this denim introduces a truly unique approach by incorporating reed fibers harvested from Lake Kojima—a material traditionally discarded despite its environmental impact.

These reeds, once removed annually to prevent pollution, are now repurposed into a functional and durable plant fiber, blended with cotton to create a fabric that is both lightly textured and surprisingly resilient. The result is a 13.5oz selvedge denim that feels natural, breathable, and subtly distinctive—offering a different character compared to conventional cotton-only denim.

Woven in Japan, this fabric reflects a philosophy of coexistence with nature, where sustainability does not compromise quality or aesthetics. The green selvedge ID—referred to as Midori Mimi—visually represents this environmental commitment, while the overall fabric maintains a clean, versatile appearance that will develop character with wear.

The silhouette is a wide straight fit with a high rise, delivering a strong vintage-inspired profile with modern wearability. It offers generous room through the top block and leg, allowing for comfort, structure, and a bold, well-balanced drape.

Details remain understated yet meaningful: green bar tacks and buttonholes, a custom duck-themed leather patch, and original Big John hardware complete the design. Every element reinforces the concept behind the garment—denim that is not only worn, but consciously made.

Fit Notes: These jeans have a standard sizing. We recommend choosing your usual size. However, as always, we recommend checking the size chart first to find your perfect size. Although the fabric is unsanforized, the jeans have been one-washed, so no further shrinkage is expected.
