The Big John M1011RC “Yoshidenim” Green Label Wild Duck Jeans represent a unique fusion of Japanese craftsmanship, sustainability, and textile innovation.

Part of Big John’s Green Label collection, this model introduces an unconventional material: reed fibers sourced from Lake Kojima. Traditionally removed to prevent environmental pollution, these reeds are repurposed and blended with cotton to create a fabric that is both functional and environmentally conscious.

The result is a 13.5oz selvedge denim composed of 94% cotton and 6% reed fiber, offering a subtle texture with a natural, breathable feel. Compared to standard denim, it delivers a slightly different hand—lightly crisp yet comfortable, with a unique character that evolves over time.

Woven in Japan, the fabric reflects a philosophy of coexistence with nature, where sustainability enhances rather than compromises quality. The green selvedge ID (Midori Mimi) visually represents this concept, while the clean surface ensures versatility for everyday wear.

The M1011RC fit is a wide straight silhouette with a high rise, offering generous room through the hips and leg. The result is a strong, vintage-inspired shape with a modern balance—structured yet easy to wear.

Details are subtle but meaningful: green bar tacks and buttonholes, a custom “Wild Duck” leather patch, and original Big John hardware reinforce the identity of the piece. Every element reflects a commitment to thoughtful design—denim that is not only worn, but consciously made.

Fit Notes: This model fits true to size for Big John, meaning the tagged size closely matches the actual waist measurement, or may even run slightly larger. Compared to most global American brands, sizing is similar, so you can take your usual size. As always, we strongly recommend checking our size chart to find your perfect size. The denim is unsanforized but has been one-washed, so no further shrinkage is expected. With regular wear, the waistband will stretch approximately 1 inch, allowing the fit to settle comfortably over time. That said, we don’t recommend sizing down, as starting too tight may cause discomfort and alter the intended fit of the garment.
