Neat ideas. I will keep them in mind for a time when I might feel the need for them. However, at risk of admitting to a bit of TMI, I own two pair of boxers and one pair of briefs. I don't know where any of them are. For the most part, I haven't worn UW since a rather "grating" experience of an amphibious landing exercise in surf that was heavily churned with sand, followed by a very long hump in the hills, some 20+ years ago.

The only time I wear UW, is for formal events (rented tux) and for Dr. appointments, one of which went badly when a pair of silk boxers exploded on me when I bent over.. for a female doctor. (re-examine Sushi's explanation on the care and life of silk).

If I were to ever rent a kilt, I would go with one of my pairs of boxers, provided I could find them, just out of respect. For my own wear, it isn't that different than my jeans, slacks, or kilts.

When it's windy... it's a challenge that I enjoy accepting.
