【MOMOTARO】#100 CLASSIC STRAIGHT 15.7oz BLACK JEANS
Classic Momotaro 15.7oz Denim
The latest Momotaro Jeans' Classic line 15.7oz denim elevates their heritage with ultra-high-density weaving from premium Zimbabwe cotton, delivering a textured, one-washed finish for immediate comfort and dramatic fading potential.
Crafted from 100% extra-long staple Zimbabwe cotton, this sanforized 15.7oz selvedge denim uses intense rope-dyed double black construction to echo with the world's deepest blue — while the vintage shuttle loom imparts slubby irregularity and softness that improves with wear.
This Momotaro 15.7oz denim is a mid-heavy weight fabric that provides superior durability and intentional detail designed to stay close to its heritage roots.
It is a nod to Momotaro’s original brand slogan created 20 years back – “Positively Superior”
Ring Dye
Everybody heard of rope-dyed denim or rope-dyed jeans. But the real aim is to create the “Ring Dye” effect.
The "ring dye" effect is a hallmark of premium denim achieved through indigo rope dyeing, where dye coats only the outer layers of yarn fibers, leaving the white core exposed for iconic fading.
A regular indigo denim yarn is dipped 8-12 times in an indigo batch on average. Whilst some denim may be dipped 16-20 times. Momotaro is known for dyeing their yarn 29-30 times to create a super dark indigo blue.
Similar technique can be applied to dyeing black yarns. While black dye are chemically attached to the yarns as opposed to the physically attached indigo dye, rope-dyeing a black denim yarn takes extra specialty to accomplish good results. Making the denim a bit more rare and costly to produce.

Detail
One-washed to minimize shrinkage (<1%) with stretch in waist. The jeans features robust details: thick top buttons, punched/ hidden rivets, roped belt loops, peach selvedge ID, jacquard pocket bags, vegetable-tanned cowhide patches, and chain-stitched hems—all embodying Okayama's artisanal excellence.
“
The point may not necessarily be the times a yarn has been dipped dyed, but rather the quality and gradation of the slowly penetrating indigo dye. We know that if you dip dye a cotton yarn too many times in an indigo dye bath, it can result in excessive dye accumulation and sticky surface. This is not ideal at all for denim weaving or aging ability. All in all, Momotaro somehow managed to achieve this dark indigo hue while preserving the abundance in blue gradience, making it one of the most sought after denim jeans on the market.
