10 Things to Know About the Super Zero® Double Black Selvedge.
1. Woven by Kowa Mill, Japan.
Established in 1894. A century of craft, known for blending heritage with innovation.
2. Made with Superzero® Yarn.
A patented Japanese yarn originally developed for high-end towels - now reimagined for denim.
3. Two Yarns, One Secret.
Cotton is twisted with a water-soluble yarn, then washed. The second yarn dissolves, leaving air pockets inside the cotton.
4. Softness from the Start.
Those air pockets make the denim light, breathable, and soft - from day one.
5. 13oz Midweight Selvedge.
The sweet spot between structure and comfort. Woven slow on old shuttle looms.
6. Double Black Dye.
Both warp and weft yarns are sulphur-dyed for a deep, matte finish that fades slowly to graphite and charcoal.
7. Red Line Selvedge.
A quiet nod to denim tradition - woven into the edge on shuttle looms in Japan.
8. No Stretch. Still Moves With You.
The Superzero yarn adds natural flexibility without using elastane.
9. A Fabric That Evolves.
Softens and blooms with wear and wash. Gets better with every year you own it.
10. A First for Hiut.
Our first collaboration with Kowa Mill. A new chapter for Double Black.
