I am a California native who is currently teaching English in Seoul, South Korea. After living in Seoul for a year and a half, I met my family in Hawaii for a week during my summer break. I had ordered my Chacos to be sent to my home in California and asked my parents to pack them, so I could have them ready for the island of Kauai. Hiking in a very muddy area (Wimea Canyon), my Chacos held up wonderfully and cleaned up nicely with simple hosing-off.
