The Selvedge Wall
Kurabo Main

Kurabo Mills, Japan

Founded over 110 years ago, Kurabo is one of the oldest manufacturers of Japanese textiles today. Their use of natural indigo dyes and unique spinning processes have set them apart from the competition. Their unsurpassed quality has gained the respect of "Denim Heads" worldwide.

Black Roller
Selvedge Main


Selvedge is the narrow, tightly woven band on either edge of the denim fabric. A selvedge end prevents the edge of the denim from unravelling and is only found on denim woven on narrow-width, antique looms.

The search never ends...

"Selecting our selvedge denims is easily the most fun I get to have each week. We're constantly discovering new denims and selvedge fabrics. I love the idea of introducing our customers to a hand-picked Suvin cotton deadstock denim or the original K-series selvedge made from the first denim ever produced in Japan."

3x1 Twill

Twill lines are the diagonal lines found on most denim. The diagonal direction comes from the 3 warp yarns going under and over the 1 weft yarn. 3x1 takes it's name in part due to this weaving pattern.

White Roller
Suvin Main


One of our finest denims is woven entirely from Suvin Cotton, the most luxurious cotton in the world. A hybrid of Sea Island cotton and Sujata cotton from India, Suvin cotton is extremely rare and expensive to produce.

Rope Dying

Rope Dying

Rope dying is considered the best possible method to dye indigo yarns. During this special process, cotton yarns are twisted into a rope and dipped into an indigo dye bath. The frequency, duration, and dye bath temperature determine the final yarn shade.

The FactoryTop to bottom, our NYC store is an homage to denim. The space houses a complete jean manufacturing facility, a one-of-a-kind experience to see inside the world of 3x1 jean-making.

The Factory

Single Needle Machines

In our universe, a single needle sewing machine is the grandmaster of tools, it's been around forever, and it only gets better with age. This gives each garment a precise, hand-tailored feeling. Some styles call for two sets of stitches meaning we actually sew each of these garments twice.

Triple Needle Machine

3x1 is all about making a jean with your very own design in mind. Even triple needle stitching, favored by workwear enthusiasts is attainable with our special sewing machine.

Quality Control

Unlike a typical denim factory, where garments are bulk manufactured and thorough inspection often falls by the wayside, every 3x1 garment is inspected a total of three times. Our head pattern maker specs every single garment with a tape measure: once before it's washed and once after. Then, our head designer does a close, physical inspection of the garment before it's pressed. A very important part of our process is always making sure that what you take home is perfect.

Cutting Table

We make a pair of jeans the way a master tailor creates a bespoke suit. The cutter places each piece of the pattern on the denim you've selected, ensuring every piece is perfectly in sync with the grain of the fabric, and then hand chalks the edges. Then, he or she cuts each piece of denim individually using shears. This is all done entirely by hand, with no automation at all, ensuring the garment we make for you fits perfectly, not one thread out of place.

Chain Stitch Machine

The Chain Stitch Machine pulls the denim at slightly different tensions on either side, causing the distinctive 'roping' that is commonly found on the hem of indigo-dyed jeans.
