The DOUBLE DIAMOND SACK COAT / PRINTED MOLESKIN is a ‘salt & pepper’ work jacket, achieved by printing a black moleskin cloth.

The sack suit has origins in 1840s France, where it is known as a sacque coat. While the coat is best known for its loose fit, the name "sack coat" comes from the garment's simple tailoring. Unlike the more intricate frock coat of the era, which is made from four back pieces, the sacque coat was much simpler, consisting of only two pieces.

The simple cut and affordability of the sack coat made it a practical outerwear choice for labourers, gaining popularity among blue-collar workers like miners, cowboys, and farmers. Its formal cut also made it suitable for public occasions and socialising with peers.

The use of moleskin as a working fabric was heavily adopted in Europe in the 19th century, with widespread use throughout France. Typically, moleskin is a dense cotton cloth that is sheared and brushed on one side to create a plush nap, resembling the texture of a mole's skin—hence its name. The soft and substantial weight made moleskin jackets and trousers favoured choices for farmers and outdoorsmen seeking warmth and wind resistance. Its tight weave also made it a suitable protective layer in factory settings where workers were likely to come into contact with sparks or hot metals.

Salt & Pepper fabric is typically created using heather yarn, but the effect can also be achieved with resist or discharge printing techniques. These methods allow for the creation of repeated stripes or patterns by either preventing the dye from taking in specified areas or by removing dye from the fabric via oxidation.

The traditional Japanese method of dyeing fabrics, known as Katazome, is achieved by applying a resist paste through a stencil. Pigment application can be done by hand painting, complete immersion, or a combination of both.

The DOUBLE DIAMOND SACK COAT / PRINTED MOLESKIN features a single-breasted, three button closure below a notched, rounded lapel.
