Has anyone found a racing short for men that actually is significantly cooler than others? I have seen ads (Performance has a lycra/coolmax short) that claim to 'breathe better' or 'wick moisture'. Also, I have wondered about lighter lycra (6oz vs. 8oz) as an alternative. It's not a big deal for me in Oregon, but, somedays it would be nice to have something that did not turn into a diaper after two hours.
