I disagree. Take a look at the pictures, that poor shirt went from a nice shiny grey in the early pictures to a dingy yellowed crusty mess in the last picture next to the truck. And his underwear which you can see in the postmortems, you can tell they have lost their color they look almost bleached out. He did get off trail at times to get cleaned up but it wasn't like most hikers. He told one hiker he only showered once a month.
