As an avid bicyclist I have always had high quality shorts around. Besides bicycling, I used them initially for racing long off-road motorcycle races, particularly woods races where you are sitting a lot. In these type of races you can get wicked monkey-butt. When I started doing 500+ mile days on a road bike, the shorts became an essential part of the kit. I recently rode a 500 mile day with some Pearl Izumi shorts, and an Alaska Leather sheepskin cover and a stock seat. I was totally fine for the whole way, but always glad to stop and get gas. I highly recommend trying bicycling shorts if your doing any all day riding.
