Sea baths, freezing denim, washing rituals that are more complex than voodoo, I'm with you, it makes no sense.
Seems like a hell of a lot of effort to go to for, well, clothes that are meant to be beater clothes.
I love seeing some fine denim, much of it raw, in the same way I love seeking Kris Van Assche sneakers. At the end of the way, though, if I'm going to trash the clothes thoroughly to pieces, I don't want to be spending top dollar for artisan quality, seems silly.
I used to freeze mine every 3 weeks when I was in the tropics. Cold soak every 6 months. That's my limit.
