Wash code DO = Dopium You read it right, not opium, Dopium. I think it's a form of more distressed Opium. I have it in the Kiedis Flaming Hearts, fabric content 67% cotton, 33% Polyester. On size 27 the measurements are: 7 ½ inch rise, 34" inseam and 15.25 inch waist. This wash also runs one size big.
