``PORTER CRAG'' is a casual series that features the depth of color and unique texture that can only be achieved through product dyeing. Used an original back satin fabric that is densely woven from a blend of nylon and cotton yarn. In order to dye the threads of different materials, we created a deep color by using ``two-bath dyeing,'' which involves soaking the yarn in two different dye solutions in succession. The drying process after dyeing creates a firm and unique texture. This series utilizes the advanced technology cultivated over many years in Kurashiki, Okayama Prefecture, which has a thriving textile industry, and uses an environmentally friendly, safe and secure dyeing process. Product dyeing produces differences in color, wrinkles, and shrinkage when finished, so you can enjoy each item's unique expression. It is also attractive because of its light weight and high storage capacity, which you cannot imagine from its appearance. The exterior of each item has a large pocket that takes advantage of the deep bag shape, making it easy to put in and take out stored items. By applying nylon tape accented with zigzag stitching to the bottom of the main unit, it matches the firm fabric and makes it easy to stand on its own. This tote bag fits A4 size and is perfect for everyday use. The handle is long enough to be worn over the shoulder. There are two partitioned pockets on the interior, and both the exterior pockets have a practical structure that has plenty of storage capacity and is easy to organize.
