Craig, I have the plain Spirit, and its sheath is hardly larger than it is. It's brown leather (or a decent fake), and doesn't stand out. I wear it at the office, and under a blazer it's invisible. Without the blazer, it seems to blend with the black belt and dark pants and no one has commented on it, though they probably wouldn't comment if they did notice. So many people carry cell phones on their belts that it doesn't seem declasse to most folks nowadays to have something hanging from your belt.
