This is an SDA special 40th edition. A 14.5oz denim using uneven yarn dyed with "Kase dyed" method by Masami Tsuji. This denim fabric is all-natural indigo dyed and woven in Ihara city, Okayama Prefecture. In this area of Japan, cotton yarn was traditionally dyed by hand; this process is called "Kase dyeing" this refers to the process of dyeing the cotton before weaving it. It is a very unique and time-consuming hand dyeing process in which colour penetration is maximized, and the yarns retain their original texture. First, the skein of yarn is wrapped and washed in water, opening the fibres to receive the dye. It is then dipped into an indigo vat for up to forty-eight hours, rinsed, and redipped. This procedure is repeated several times. Once the desired colour is achieved, the yarn is steamed to fix the dye to the fibres. Because it does not use as many chemicals as other forms of dyeing, Kasezome is less damaging to the material. The final indigo colour is also usually more vibrant than those achieved by other dyeing methods. Of course, merely hand-dyeing it's not enough to make it good. It is crucial to have an in-depth knowledge of indigo and years of accumulated experience.

Among its details, we can find a fantastic embossed pony hair 40th-anniversary leather patch, Studio D'artisan custom hardware or a hidden coin pocket selvedge.

The cut is the new SDA Tapered fit, simple taper from the knee down with a close leg opening, still offering plenty of room in the thigh and top block with a high rise.
