I've now worn my jeans for eight months, effective time. I have soaked them with detergent several times before but never actually washed them. The soaks didn't remove any color but unfortunately not much else either, so I had to give the jeans a wash.
Please note that the color is not as blue as in the outdoor pictures.
Perhaps the most accurate representation of the color.
Compared to 8 months APC.
I think that the Samurai denim is clearly better than that of APC. More shades, more color, heavier weight. The APC denim gets a nice, grainy texture after a year or so and several washes, though.
After wash. I only washed them in 40*C so they didn't lose much color at all. The biggest difference is the thighs, they were more greyish before the wash.
It's a big plus that they don't lose much color from a wash, that means you'll get almost all fading from actual wear and not just from washing. This is why Japanese denim is famous.
I have repaired the backpocket many times. The snap on my wallet has almost worn through three layers of denim.
The denim of the backpocket is getting thin in many places, so I have put a patch covering the whole inside of the backpocket. I made the patch from the cut-off denim I got when I hemmed the jeans and I hope to get a nice change of shade in the most worn places, from light blue back to dark blue, and then to light blue again!
