I have been wearing the white version for almost a year and a half. Just got back from packing up a long camping trip and they were so dirty, they were almost black. Sponge/scrubbie and some dish soap and they look brand new, very white. The little black label comes off after some wear, and I slightly melted the toe area from my huge campfire. Buying at least two more pairs soon...don't ever want to be without them.
