This denim looks great. IH 25oz XHS is one of my favorites, hands down, ever. I really like the idea of the black weft, and the potential for high-contrast fades. These are definitely on my radar.
I've come to find that I think the 634 is better suited for me than the 888. There's a little too much rise and extra width in the hips on the 888 for my build. The 555 is a too slim in the thighs. My 888NT 34's are way too big. I'd need to size down to a 33, and perhaps a 32, so they sit at my waist and not drop down to my hips. I really like the slight taper below the knee, and tweaks to the pockets. I'll have to review the measurements when released.
Sorry if this has already been answered previously, but how much shrink is there in this XHS variant? I've found the original XHS shrank about 1/2 size over several washings.
