I've washed them in the wading machine (cold/cold) with a sun dry about 5 times. The indigo is staying nicely, but it looks like much of the brown overdye has lightened up. They are also fairly hairy now. The fades are also looking nice, but not that pronounced yet. I've worn them to 5 concerts and I sweat crazily, so that has helped the evo a bit, that's also why I've washed them so much.
