[DESIGN] This zip sweat jacket is made using an old-fashioned knitting machine and features a sturdy, heavy-duty fleece material. The fabric is woven with a high density, almost dense weave, giving it a heavy appearance while also being soft and comfortable. This makes it a versatile item that can be used as both an inner and outer layer in a wide range of situations. Another feature of the round body fleece ZIP CREW is that it is made using a method called "round body." Regular clothing has seams under the arms, but round body construction has no seams and is made by knitting a single piece of fabric into a tube shape. This construction means that there are no seams in contact with the skin, reducing stress when worn and making the garment extremely comfortable against the skin. In addition, the lack of seams improves elasticity and allows the garment to fit naturally to the body, making it extremely easy to move around in. This zip sweat jacket is simple yet detailed in design and comfortable to wear, making it a versatile piece for any season. This item combines functionality and style, making it suitable for a wide range of situations, from everyday use to outdoor activities and relaxing occasions. [PROCESSING] What is SP processing (special processing)? Sweatshirts from the 1930s to the late 1960s were primarily dyed with direct and sulfur dyes. The mechanism by which old clothes fade is thought to be an oxidative bond between oxygen in the air and the amino acids that hold the dye in place, causing hydrolysis, which turns them into carbon and decays. REMI RELIEF's SP processing reproduces this natural principle, using traditional direct dyes that are then combined with oxygen to fade the dye slowly over a long period of time. The body of the garment is damaged to a certain extent, but unlike processing that involves the addition of chemicals or forcibly dissolving the fabric with bio-based methods, this natural processing gives the garment an appearance that is closest to the damage that occurs naturally over time in vintage clothing, and the more you wear it the more indistinguishable it becomes from real vintage clothing. [MATERIAL] 100% COTTON The yarn used for the fleece is made from organic cotton "waste" grown at Alvarez Farm in New Mexico, USA. The yarn is characterized by its stiffness and tension, and is knitted at the very limit of the gauge to create a very dense and stiff fleece. The fabric is unbrushed, making it easy to use all year round. 【COUNTRY】 Made in Japan [MODEL SIZE] 177cm 58kg wearing size M [SIZE] SIZE(cm) shoulder width Chest width Sleeve Length Length SMALL 57 58 55 65 MEDIUM 58 59 57 67 LARGE 59 60 59 69 X-LARGE 60 61 61 71 *Due to the nature of processed products, the actual size may differ by 1 to 2 cm from the stated size.
