Yeah, they are "black", but they look pretty bluish in regular light. I think they use indigo dye but could be overdyed, I am not that much of a denim expert. I've worn them like 50-60% of the days since I got them, which was some time in early/mid April. So that's about 45-60ish days by my PBR-enhanced math. I haven't washed them yet, but I think they either came rinsed or one of the two or three other SFers who tried them before me washed them once, since there is roping to the hems. This is some of the toughest material and dye I've seen yet, TBH, and they're not very heavy weight either. I'd actually like to pick up another pair as a backup, they are one of my faves.
