OK, after seeing the "should I wash my shorts thread after sweating in them for an hour" thread, it made me think about an issue I have with shorts. Not sure how I differ anatomically, but it seems the chamois positioning in all my shorts is off. The widest part of the chamois is always positioned too far back when I ride so that I end up sitting on the narrow part - I'm sure you've seen riders with the fat part of the chamois outline further up their back rather than matching the saddle outline. Anyone else have this issue? I have PIs and a pair of Nikes and it's the same thing with both.
