This sweat top was born from the origins of American sportswear before the 1950s, when man-made materials became widely used. Like Lot.601 Tee Shirt, it has a direct cut and flat shape. By reconstructing this top, we can understand the background of the manufacturing process that has been forgotten in the modern age, such as the V-gusset sweat stop detail at the neck on the front and back sides of the shirt. The fabric is made of USA cotton, which has a unique texture with a dry feel. The hang knitting machine, which was introduced to Japan in the Taisho era (1912-1926) and is currently the only one in the world operating in Wakayama Prefecture, can knit only one meter per hour, making it very inefficient, but the slow process results in a fabric with a unique texture with just the right amount of unevenness, as if air were knitted in together.
