Lisa - Thanks for the information. Do you have an idea of size comparison with Pearl Izumi or Cannondale? I have PI medium shorts that seem loose, and PI small capris that are snug, but not too, and Cannondale small shorts that fit pretty well, but they're a little tight in the thighs. I know it's hard to extrapolate from this, it sounds like a medium SB might be the way to go (for a, um, well-rounded fiftysomething!)
