The 15 oz. denim is woven from undyed ecru warp and weft yarns on a vintage GL-3 loom manufactured by Toyoda Automatic Loom Works, now known as Toyota Industries Corporation. After the jacket is cut and sewn, the finished garment is dyed on Amami Oshima using the traditional Amami Dorozome mud-dyeing process. It is repeatedly immersed in a botanical dye extracted primarily from the local Techi tree (Rhaphiolepis indica var. umbellata, also known in Japanese as Sharinbai), then immersed in iron-rich mud to deepen and fix the color. This process produces an earthy brown tone with subtle variations from piece to piece. The finished jacket combines the irregular surface character of GL-3-woven denim with the natural depth of color created by traditional Amami mud dyeing, while retaining the practical construction and everyday wearability of a classic work jacket. \u003cbr\u003e\u003cbr\u003e\u003cb\u003eSize and Fit Guide:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003eGender: Men.\u003cbr\u003e\u003cbr\u003eThe jacket is cut with a modest amount of room through the chest and torso, while the shoulders remain close to their natural position rather than extending into a dropped-shoulder shape. The body falls almost straight from the chest to the hem without pronounced waist shaping, creating a classic work jacket silhouette that is not close-fitting. At the same time, it is not an exaggerated modern oversized fit. The body length is intentionally short and finishes around the waist, reflecting the proportions of vintage work jackets.

The jacket is constructed from substantial 15 oz. cotton denim woven from undyed ecru warp and weft yarns. After construction, the garment is dyed to create its earthy brown color.\u003cbr\u003e\u003cbr\u003eThe design is characterized by a short body length, vertically arranged front pleats, lower patch pockets, action pleats across the back, and an adjustable cinch-back strap. These functional details are derived from early workwear construction, but Studio D'Artisan has modified the overall balance and fabric specification to create a jacket suitable for contemporary casual wear.\u003cbr\u003e\u003cbr\u003eThis is an unlined, single-layer jacket. It can be worn as a light outer layer during spring and fall, over a T-shirt or lightweight shirt in milder weather, or as an intermediate layer under a heavier coat during colder seasons.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSilhouette and Fit\u003c\/strong\u003e\u003cbr\u003eThe jacket has a classic work-jacket silhouette with moderate room through the chest and torso, a relatively short body length, and a straight shape from the chest to the hem. It is not cut closely to follow the contours of the body, but it is also not designed with the substantially dropped shoulders or exaggerated proportions associated with modern oversized clothing.\u003cbr\u003e\u003cbr\u003eThe shoulder width is kept relatively natural, allowing the set-in sleeves to follow the wearer's shoulder line without creating excessive volume. The chest and body provide practical ease of movement, while the short length allows the hem to sit around the waist or upper hip area, depending on the wearer's height and body proportions.\u003cbr\u003e\u003cbr\u003eThe sleeves are designed with a standard length and a conventional set-in construction. The overall fit reflects the proportions of a vintage work jacket, providing enough room for layering while maintaining a controlled and balanced appearance.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003e15 oz. GL-3 Loom-Woven Denim\u003c\/strong\u003e\u003cbr\u003eThe jacket is made from 15 oz. denim woven from 100% cotton yarn on a Toyoda GL-3 power loom. The GL-3 was one of the earliest power looms developed in Japan and represents an important stage in the development of the Japanese textile industry.\u003cbr\u003e\u003cbr\u003eUnlike modern high-speed weaving equipment, the GL-3 operates at an extremely low production rate. It is capable of weaving only approximately five meters of fabric per hour. This slow weaving speed allows the yarns to retain more of their natural irregularity and prevents the fabric from becoming excessively compressed or mechanically uniform.\u003cbr\u003e\u003cbr\u003eReplacement components for the GL-3 are no longer commercially produced. Maintaining an operational loom may require usable parts to be recovered from other retired GL-3 machines. The limited availability of replacement parts, specialized mechanical adjustment, and low production efficiency make the continued use of this loom exceptionally labor-intensive.\u003cbr\u003e\u003cbr\u003eThe resulting denim has a firm, substantial hand with visible surface irregularity. Natural yarn thickness variation produces small neps, raised fibers, and uneven areas across the fabric. These characteristics are not manufacturing defects. They are inherent features of denim produced on early low-speed weaving equipment.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eStudio D'Artisan Original Denim Specification\u003c\/strong\u003e\u003cbr\u003eThe denim was developed according to Studio D'Artisan's original fabric specification. The yarn count, yarn irregularity, warp and weft density, and weaving tension were selected to emphasize the distinctive characteristics of the GL-3 loom.\u003cbr\u003e\u003cbr\u003eBoth the warp and weft yarns are initially undyed ecru cotton. This differs from conventional blue denim, which is normally woven with indigo-dyed warp yarns and undyed weft yarns. By beginning with an entirely ecru denim base, the finished fabric can absorb the Amami Dorozome dye across both sets of yarns, producing a brown color that extends throughout the structure of the cloth.\u003cbr\u003e\u003cbr\u003eThe combination of irregular yarns, low-speed weaving, and substantial 15 oz. weight gives the fabric a pronounced three-dimensional surface. The cloth is not uniformly smooth. Instead, it contains subtle changes in yarn thickness, tension, and elevation that become more visible as the jacket is worn and washed.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eAmami Dorozome Mud-Dyeing Process\u003c\/strong\u003e\u003cbr\u003eThe jacket is dyed using Amami Dorozome, a traditional dyeing technique practiced on Amami Oshima, an island in southern Japan. The process uses dye extracted from the locally grown Techi tree, also known as Sharinbai in Japanese. Its botanical classification is Rhaphiolepis indica var. umbellata.\u003cbr\u003e\u003cbr\u003eThe wood and bark of the Techi tree contain natural tannins. These materials are processed to create a botanical dye bath, and the garment is repeatedly immersed in the solution so that the tannins can penetrate the cotton fibers. The garment is then treated with the iron-rich mud found on Amami Oshima.\u003cbr\u003e\u003cbr\u003eThe iron in the mud reacts with the tannins absorbed into the fabric. This natural chemical reaction darkens the material and helps fix the color within the cotton fibers. Repeated botanical-dye and mud-treatment cycles gradually build the final earthy brown tone.\u003cbr\u003e\u003cbr\u003eBecause the coloration is created through repeated interaction between plant-derived tannins, iron-rich mud, water, cotton yarn, and manual processing, the resulting shade is not mechanically uniform. Minor variations in depth, surface tone, and color concentration may occur between individual garments and between different areas of the same garment. These variations are characteristic of the traditional dyeing method.\u003cbr\u003e\u003cbr\u003eThe finished color has a natural soil-like depth that differs from the flatter and more uniform appearance commonly produced by conventional synthetic dyes. The brown tone also emphasizes the neps, raised fibers, and irregular texture of the GL-3-woven denim.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eOne-Wash Finish\u003c\/strong\u003e\u003cbr\u003eThe finished jacket has been washed once before sale. This one-wash treatment removes a portion of the initial shrinkage and softens the rigid feel of newly woven denim, allowing the jacket to feel more comfortable and easier to wear from the beginning.\u003cbr\u003e\u003cbr\u003eAlthough the one-wash process stabilizes the fabric to a certain degree, minor additional shrinkage or dimensional change may still occur depending on water temperature, washing method, drying conditions, and frequency of laundering. Cold water and natural air drying are recommended to reduce unnecessary shrinkage and color loss.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eWear and Color Development\u003c\/strong\u003e\u003cbr\u003eThe mud-dyed surface will gradually change through repeated wear, friction, movement, and washing. Areas exposed to frequent contact, including the seams, front pleats, pocket openings, cuffs, elbows, collar edges, and waistband, may develop lighter tones and more pronounced surface contrast.\u003cbr\u003e\u003cbr\u003eThe raised portions of the irregular denim surface will generally receive more abrasion than the recessed areas. This difference in friction can emphasize the fabric's uneven texture over time. The resulting color variation will depend on how the jacket is worn, how frequently it is washed, and the conditions in which it is used.\u003cbr\u003e\u003cbr\u003eBecause natural dyeing does not produce the same perfectly uniform and highly colorfast surface as some modern synthetic dye systems, gradual color transfer and fading should be regarded as inherent characteristics of the garment.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eCollar Construction\u003c\/strong\u003e\u003cbr\u003eThe jacket has a simple shirt-style collar without a separate collar stand. The collar is attached directly to the neckline rather than being mounted on a raised band.\u003cbr\u003e\u003cbr\u003eThis construction keeps the collar base relatively low and creates a flatter roll than a collar with a separate stand. The result is a compact neckline that is consistent with the direct and functional construction of early work jackets.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eFive-Button Front Closure\u003c\/strong\u003e\u003cbr\u003eThe front closes with five metal buttons positioned vertically along the front opening. The buttonholes are sewn horizontally, a traditional orientation that helps the button remain seated against lateral pulling forces generated when the wearer moves the arms or expands the chest.\u003cbr\u003e\u003cbr\u003eThe front placket is formed by folding the denim back on itself to create a double-layer structure. This reinforces the button and buttonhole area, helps control stretching along the front opening, and provides additional resistance to distortion during repeated fastening and unfastening.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eVertical Front Pleats\u003c\/strong\u003e\u003cbr\u003eFour vertical front pleats are incorporated into the front body, with two pleats positioned on each side of the front opening. The pleats run parallel to the button placket, extending from below the front yoke to the upper edge of the waistband.\u003cbr\u003e\u003cbr\u003eEach pleat is formed by folding a section of the front-body fabric inward and securing the fold at three separate points with horizontal rows of stitching. This construction retains a controlled amount of additional fabric within each front panel.\u003cbr\u003e\u003cbr\u003eWhen the wearer reaches forward, raises the arms, or expands the chest, the folded sections can open slightly to provide additional ease across the chest and front body. This helps compensate for the limited stretch of the substantial 15 oz. denim and reduces pulling around the button placket, armholes, and upper front panels.\u003cbr\u003e\u003cbr\u003eWhen the wearer returns to a neutral position, the pleats settle back into their folded configuration. This allows the front body to maintain a relatively flat and controlled appearance without the permanent fullness that would result from a wider body pattern.\u003cbr\u003e\u003cbr\u003eIn addition to their functional purpose, the four pleats create pronounced vertical lines extending along both sides of the front opening. This construction emphasizes the elongated panel structure and distinctive appearance associated with early work-jacket design.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eLower Patch Pockets\u003c\/strong\u003e\u003cbr\u003eTwo patch pockets are positioned on the lower front body, one on each side. The pockets have an open-top design without flaps, providing direct access while maintaining a simple and functional appearance.\u003cbr\u003e\u003cbr\u003eThe upper corners of each pocket are reinforced with metal rivets. These locations receive concentrated stress when the wearer inserts a hand or carries an object inside the pocket. The rivets help distribute this load and reduce the possibility of the pocket corners separating from the body fabric.\u003cbr\u003e\u003cbr\u003eThe pockets are constructed from the same 15 oz. mud-dyed denim as the main body. As the jacket is worn, the pocket edges and riveted corners may develop visible abrasion and color contrast.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSet-In Sleeve Construction\u003c\/strong\u003e\u003cbr\u003eThe sleeves are attached to the body with conventional set-in armholes. Unlike a dropped-shoulder or raglan construction, the sleeve seam is positioned close to the natural shoulder point.\u003cbr\u003e\u003cbr\u003eThis construction gives the shoulder area a controlled shape and allows the sleeve to extend naturally from the upper body. It also helps preserve the structured appearance associated with classic work jackets.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eButton Cuffs and Riveted Cuff Slits\u003c\/strong\u003e\u003cbr\u003eEach sleeve is finished with a single-button cuff. A cuff slit is positioned above the cuff opening to provide enough space for the hand to pass through the sleeve and to allow the cuff to open during dressing.\u003cbr\u003e\u003cbr\u003eA reinforcing metal rivet is installed at the upper end of each cuff slit. This point is exposed to repeated pulling and concentrated stress when the cuff is opened, closed, or pulled over the hand. The rivet helps reduce the risk of the slit extending or tearing into the sleeve fabric.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eBlack-Coated Metal Buttons\u003c\/strong\u003e\u003cbr\u003eThe front and cuff buttons are made from metal and finished with a black coating. Each button is stamped with the Studio D'Artisan brand logo.\u003cbr\u003e\u003cbr\u003eThe dark hardware coordinates with the earthy brown denim while maintaining a restrained industrial appearance. With extended wear, friction may gradually alter the surface of the black coating, particularly along raised edges and areas that frequently contact the buttonholes.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eStraight Back Yoke\u003c\/strong\u003e\u003cbr\u003eThe upper back is divided by a straight horizontal yoke extending across the shoulders. This yoke supports the upper portion of the jacket and provides a stable structural transition between the shoulder area and the lower back panels.\u003cbr\u003e\u003cbr\u003eBelow the yoke, the back body is constructed from two panels joined by a vertical center seam. The center seam helps shape and stabilize the wide back area while maintaining the symmetrical appearance of the jacket.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eRear Action Pleats\u003c\/strong\u003e\u003cbr\u003eVertical action pleats are positioned on both sides of the back body. The pleats extend from below the back yoke toward the waistband area.\u003cbr\u003e\u003cbr\u003eWhen the wearer reaches forward, lifts the arms, or moves the shoulders, these pleats can open to release additional fabric across the upper back. This increases mobility through the shoulder blades and reduces the amount of pulling transferred directly to the armholes, shoulder seams, and back yoke.\u003cbr\u003e\u003cbr\u003eWhen the arms return to a neutral position, the pleats fold back toward the body. This allows the jacket to provide additional movement without requiring a permanently wide or oversized back silhouette.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eAdjustable Cinch-Back Strap\u003c\/strong\u003e\u003cbr\u003eAn adjustable cinch-back strap is positioned near the lower back. The two ends of the strap are secured to the body with metal rivets, and the strap passes through a metal buckle.\u003cbr\u003e\u003cbr\u003eTightening the buckle draws in a portion of the fabric at the rear waistband, allowing the wearer to make a limited adjustment to the circumference and shape of the lower back. Loosening the strap restores more room through the hem.\u003cbr\u003e\u003cbr\u003eThe cinch-back is both a functional adjustment device and a characteristic detail associated with early workwear construction.\u003cbr\u003e\u003cbr\u003ePlease note that the exposed buckle and rivets may scratch or abrade surfaces such as automobile seats, leather or fabric sofas, chairs, painted furniture, and other finished materials. Care should be taken when sitting or leaning against delicate surfaces.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eLeather Brand Patch\u003c\/strong\u003e\u003cbr\u003eA Studio D'Artisan leather brand patch is attached inside the jacket at the back of the neck. The leather will gradually soften and change in tone with exposure to movement, moisture, body heat, and repeated wear.\u003cbr\u003e\u003cbr\u003eNatural differences in grain, color, and surface texture may be visible in the leather.

Until the initial excess color has gradually been reduced through wear and washing, the jacket should be kept away from light-colored clothing, bags, upholstery, footwear, and other items that may easily absorb pigment.\u003cbr\u003e\u003cbr\u003eColor transfer may occur when the jacket is dry, but the risk increases when the fabric is damp from rain, perspiration, washing, or high humidity. Friction at the cuffs, underarms, waistband, collar, and areas that contact bags or seats may also cause pigment to transfer.\u003cbr\u003e\u003cbr\u003eDo not place the wet or damp garment directly against other clothing or household surfaces. Do not leave the jacket soaking in water or folded while wet, as dissolved dye may migrate and create uneven staining.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eWashing and Care Precautions\u003c\/strong\u003e\u003cbr\u003eWash this jacket separately from other garments. Use cold water and a mild detergent. Do not use chlorine bleach, oxygen bleach, hot water, or a tumble dryer.\u003cbr\u003e\u003cbr\u003eAfter washing, remove the jacket promptly, reshape it carefully, and allow it to air-dry in the shade. Avoid leaving the garment wet for an extended period. Prolonged soaking or contact with other wet materials may cause dye to bleed or transfer.\u003cbr\u003e\u003cbr\u003eBecause of the natural dyeing process, some color loss is expected during washing. Variations in fading and surface color are part of the intended character of the garment.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eMade in Japan\u003c\/strong\u003e\u003cbr\u003eThe jacket is made in Japan using Studio D'Artisan's original 15 oz.

It was developed before the widespread adoption of modern high-speed textile machinery and reflects an earlier stage of Japanese weaving technology.\u003cbr\u003e\u003cbr\u003eOnly a limited number of GL-3 looms remain in operation today. Their rarity, low production capacity, and distinctive weaving characteristics have made them highly valued for producing specialized fabrics with pronounced surface variation.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eDifficult to Maintain\u003c\/strong\u003e\u003cbr\u003eReplacement parts for the GL-3 are no longer commercially manufactured. When a component becomes worn or damaged, usable parts may need to be recovered from another retired or non-operational GL-3 loom.\u003cbr\u003e\u003cbr\u003eKeeping the machine in working condition requires experienced technicians who understand its mechanical timing, shuttle movement, yarn tension, take-up system, and other operating characteristics.\u003cbr\u003e\u003cbr\u003eSmall changes in alignment or mechanical adjustment can affect both the stability of the weaving process and the appearance of the finished fabric. Regular inspection, careful adjustment, and continued maintenance are therefore essential.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eExtremely Slow Weaving Speed\u003c\/strong\u003e\u003cbr\u003eA GL-3 can weave only approximately five meters of fabric per hour. This is considerably slower than contemporary high-speed looms designed for large-scale industrial production.\u003cbr\u003e\u003cbr\u003eFrom a manufacturing perspective, the GL-3 is highly inefficient. It requires more time, closer supervision, and greater mechanical attention to produce a relatively small quantity of fabric.\u003cbr\u003e\u003cbr\u003eHowever, the slow operating speed allows the yarns to be woven without creating the highly compressed, smooth, and mechanically uniform surface commonly associated with modern mass-produced textiles.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eWhy the GL-3 Is Called a \"Phantom Loom\"\u003c\/strong\u003e\u003cbr\u003eThe GL-3 is sometimes referred to as a \"phantom loom\" because very few operational machines remain, replacement parts are difficult to obtain, and the technical knowledge required to maintain them is increasingly specialized.\u003cbr\u003e\u003cbr\u003eThe term also refers to the distinctive fabric character produced by the machine. Depending on the yarn and weaving specification, the GL-3 can produce visible neps, slubs, uneven elevations, and subtle variations in surface density that are difficult to reproduce with modern high-speed equipment.\u003cbr\u003e\u003cbr\u003eThese characteristics are not manufacturing defects. They result from the combination of irregular yarns, low-speed weaving, carefully controlled tension, and the mechanical properties of the older loom.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eFabric Characteristics Produced by the GL-3\u003c\/strong\u003e\u003cbr\u003eFabric woven on the GL-3 typically has a substantial hand and a visibly irregular surface. Differences in yarn thickness, tension, and placement create raised and recessed areas throughout the cloth.\u003cbr\u003e\u003cbr\u003eSmall neps, slubs, loose surface fibers, and variations in texture may be visible. Neps are small groups of entangled fibers, while slubs are thicker sections formed within intentionally irregular yarns.\u003cbr\u003e\u003cbr\u003eRather than appearing perfectly flat and uniform, the surface contains subtle variations that become more noticeable under changing light and through continued use.\u003cbr\u003e\u003cbr\u003eThe exact appearance and hand of the fabric depend on the yarn count, yarn irregularity, warp density, weft density, weaving tension, and other production specifications selected for each fabric.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eCraftsmanship Rather Than Production Efficiency\u003c\/strong\u003e\u003cbr\u003eProducing fabric on the GL-3 requires substantially more time and manual involvement than weaving on modern industrial machinery.\u003cbr\u003e\u003cbr\u003eThe loom must be carefully maintained, weaving conditions must be monitored, and mechanical adjustments may be required during production. The objective is not maximum output or complete visual uniformity, but the creation of fabric with controlled irregularity and distinctive surface character.\u003cbr\u003e\u003cbr\u003eEach length of fabric reflects the interaction between the loom, the yarn specification, the mechanical settings, and the judgment of the loom operator.\u003cbr\u003e\u003cbr\u003eThe GL-3 therefore represents a production method that prioritizes fabric character, technical skill, and careful small-scale manufacturing over speed and efficiency.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eHandling Amami Dorozome Mud-Dyed Products\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eTraditional Amami Dorozome Dyeing\u003c\/strong\u003e\u003cbr\u003eAmami Dorozome is a traditional mud-dyeing method practiced on Amami Oshima in southern Japan.\u003cbr\u003e\u003cbr\u003eThe process uses a botanical dye extracted from the Techi tree, also known in Japanese as Sharinbai. The wood and bark contain natural tannins that can bond with textile fibers and react with iron.\u003cbr\u003e\u003cbr\u003eThe material is repeatedly immersed in the plant-based dye solution so that the tannins penetrate the fibers. It is then treated with iron-rich mud from Amami Oshima.\u003cbr\u003e\u003cbr\u003eThe iron in the mud reacts with the tannins and gradually deepens and fixes the color. Multiple dyeing and mud-treatment cycles are required to build the characteristic earthy tone.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eNatural Color Variation\u003c\/strong\u003e\u003cbr\u003eAmami Dorozome does not produce the mechanically uniform appearance associated with conventional synthetic dyeing.\u003cbr\u003e\u003cbr\u003eMinor differences in color depth, concentration, and surface tone may occur between individual products. Subtle variations may also be visible within different areas of the same product.\u003cbr\u003e\u003cbr\u003eSeams, folds, reinforced areas, and sections containing multiple layers of fabric may absorb or retain the dye differently from single-layer areas.\u003cbr\u003e\u003cbr\u003eThese variations are inherent characteristics of the traditional dyeing process and should not be regarded as defects.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eColor Transfer Through Friction\u003c\/strong\u003e\u003cbr\u003eNatural dye remaining on or near the surface may transfer to other materials through friction.\u003cbr\u003e\u003cbr\u003eParticular care should be taken when a mud-dyed product comes into contact with white or light-colored clothing, bags, shoes, furniture, automobile seats, upholstery, or other finished surfaces.\u003cbr\u003e\u003cbr\u003eAreas exposed to repeated rubbing may release color more readily.
