Well, it went from completely white, with 900 miles on it, to smudged grey where my thighs rub, 15 miles later. At first I thought it was some sort of residue from a 5-mile stretch of new pavement, but it kept getting worse over the next 105. I'm pretty sure it's the dye - and I had never worn those tights on any non-black saddle before. And it does seem to be lifting a little.

I thought about covering it with shoe polish or something, but wouldn't that transfer to my shorts? Hmmm - some sort of skunk butt effect?

I'm going to keep working on it.
