I have read the article and concur with it almost entirely. Especially the part that says:
Finally!!! -- NEVER... NEVER... NEVER... WEAR UNDERWEAR UNDER A BIKE SHORT
Panels are the number of pieces of fabric that are used in the construction of the shorts. More panels means better fit. More panels also means more seams, but better quality shorts have seams on the outside, flat-lock stitching, or even fused seams.
The chamois is indeed about moisture management and the prevention of chafing. It also provides a little cush for your tush.
If you haven't tried a pair of padded lycra cycling shorts yet, you're in for a treat. Buy the best shorts you can afford. And never, under any circumstances, for any reason, wear underwear under your bike shorts!
Got it?
Good!
