My most favorite shorts to date are by Pearl Izumi. I believe it is there Sugar short. They have a synthetic chamois that I believe is purple and another color though that was last seasons short. I have tried several different brands and they are still my favorite. The chamois is smooth it doesn't bunch. I also like the length of the short. It isn't too long hitting about mid thigh. I think they cost around $45. Hope this helps.
