I always find it hilarious when a new, local team pops up, and they start "experimenting" with white-based shorts. Hahahaha. After the first time it rains on them, they are sooooooo sorry. It's basically naked cycling with a chamois.
We had baby blue kits a few seasons ago, and after about year, the lyrca was wearing down to almost see through. It was the worst for the women though, as you could basically see their ass right through their shorts when you rode behind them.
I have to say though, I am more aware/sensitive to the issues of chafing and comfort then any non-cyclist. Having something smooth on your butt and on your skin is so critical when you're in the saddle for 7 hours at the time. I also use chamois butt'r.
My favorite is "Smooth Ride".
I also found out that it's fun to use on your parnter in bed.
