This sweatshirt is versatile, suitable as a main piece or as a layering item under jackets. The material is 100% cotton, a moderately thick 13-ounce fleece sweatshirt fabric. It has a dry texture and uneven weave that evokes the good old days of America, giving it a soft feel that highlights the original texture of the yarn. The fleece lining provides warmth, offering a comfortable yet supple feel. This product is made using a "circular knitting machine." Circular knitting machines are old-fashioned machines that knit fabric in a tubular shape. Although production efficiency is low, they knit slowly, without applying excessive tension, allowing the soft texture of the yarn to be preserved. This rare machine creates fabric with a warm, rich appearance, along with a comfortable and supple feel. The biggest feature of sweatshirts made with circular knitting machines is the "tube body" construction, which means there are no seams on the sides of the body. Nowadays, high-speed knitting machines that prioritize mass production are the mainstream, and circular knitting machines are becoming outdated technology. However, sweatshirts made with circular knitting machines possess a unique texture and timeless toughness that cannot be achieved with high-speed machines. By intentionally using the low-efficiency circular knitting machine, the fabric is knitted into a strong tube body that is soft and airy. Also, because the garment has no seams, there is no seam rubbing against the skin, providing a comfortable fit. The neck rib (collar) features a durable binder neck with a two-needle stitch, which is resistant to stretching even after repeated wear. A V-gusset (sweat guard) is provided at the front collar, and the cuffs and hem ribs are slightly longer, creating a vintage feel. The armholes, sleeves, and side seams are sewn with a flat seamer. Flat seams have no bulk on the back of the fabric when stitched, resulting in a flat finish that reduces stress against the skin and enhances comfort.
