I bought a few pair of shorts and I plan on using my bike shorts underneath because they are so thin except for the liner seat area. Then when I get to work I plan on just swapping the underwear. It's a plan anyway. When commuting there is no getting away from the issue of clothing and there are lots of options. There's nothing like field testing a plan to bring home the realities that will govern your specific application. The cycling underwear listed above are a great price.
