There are many products, but they all boil down to one thing: Eliminating friction and moisture.
Even better is that all these products which help to heal you after, these same chamois cremes and bag balms, are designed to prevent saddle sores. Grandma always said an ounce of prevention is better than a pound of cure, right?
Gold Bond, bag balm, or Assos After Ride Skin Repair gel all work well. Loose clothes, not so much. They tend to allow the skin contact which is best avoided once saddle sores or chafing come to visit.
I've used chamois creme applied directly on the skin after a ride, and that is quite effective as well. Look for Assos Chamois Creme, DZ Nuts, or Chamois Butt'r.
I hope that helps.
