Blue refabric / 17oz Selvedge Monster Denim Semi-Wide Tapered 5-Pocket Jeans

Blue refabric
Built on a commitment to high-quality Japanese fabrics and meticulous craftsmanship, Blue refabric was produced for many years as a ROCOCO-exclusive collection with Japan Blue Jeans before relaunching under its own name in 2026.

Production takes place primarily at partner factories of Japan Blue Co., Ltd. The brand name combines “Blue,” representing Japanese denim, with “Refabric,” a coined word blending “Republic” and “Fabric.” Inspired by the idea of a “Blue Republic,” the brand celebrates Japan’s rich textile heritage while creating garments that bring out the individuality of the wearer.

Using premium denim from Okayama Prefecture and other high-quality Japanese fabrics, each piece is carefully crafted at trusted factories across Japan. The designs are minimalist yet distinctive, allowing the natural character and texture of the materials to take center stage.

From Japan, a country with a rich textile heritage, to the world. Blue refabric presents a new standard rooted in a deep appreciation for Japanese textiles.

New 17oz Deadstock Denim
Crafted from substantial 17oz denim, these jeans have a rugged character and a solid, heavyweight feel. Despite their substantial construction, the denim gradually softens and molds to your body with wear, developing unique fades and wear marks over time.

Starting with a deep indigo hue, the denim gradually takes on a character all its own. The pleasure of breaking them in and watching them evolve over time is part of what makes these jeans so special.





The jeans feature a convenient zip fly.



The jeans feature a classic five-pocket design.
A red selvedge edge peeks out from inside the coin pocket, showcasing the character of the denim in even the smallest details.





A leather patch is placed on the back to add a distinctive brand accent.
As the denim is worn in, the patch develops alongside the fabric, adding another element of aging and character to the back view.



The fabric edges feature selvedge denim, an iconic detail of vintage denim.



The interior features a “COLLECT DENIM HEADS / Japan Blue Co., Ltd.” label.
This indicates production at one of Japan Blue Co., Ltd.’s partner factories.





A semi-wide tapered silhouette with room through the hips and thighs, gradually narrowing from the knees to the hem.

The relaxed thigh area provides comfort without feeling restrictive, while the clean hem keeps the overall look refined. The balance highlights the bold presence of heavyweight denim without appearing overly bulky.
