Shooting Star, I didn't buy the wicking thong for cycling. Like I said, I never wear underwear with cycling shorts. But I wanted to wear them under my hiking shorts or pants in warmer weather. In cold weather I wear long underwear.
I am short and small (5' 1", 105), too, but I guess my bum must be bigger than yours! I do care about vpl and I think it looks gross. Wearing thongs with regular clothes doesn't bother me at all. It took me a long time to find 2 brands that fit me and didn't show anywhere. To me, the point of wearing a thong is so nothing shows and you have no lines anywhere. I finally went to a real lingerie store to find what I wanted.
And Lisa, you are right. Any chamois that folds like a diaper has something wrong with it. I wear Terry and Sheebest and have no issues. The Sheebest feels a little thicker, but it's in different places.
