WRT boxer-briefs: I travel a lot, and there isn't much that is less comfortable than bad underpants 16 hours into a 38-hour journey to the upside-down side of the planet. I decided to try a pair of Tilley Endurables Coolmax Extreme boxers. Expensive, but I've since bought two more pairs. They don't bunch, they wick, they don't develop the stinkiest of stinks. When I get to my hotel, I wash them in the sink and they are good to go in about eight hours.
