I have used Chamois Butt'r for 3 year when the daily milage goes over 30 miles with 150-200 weekly totals and have had great luck with it, but this spring I gave bag balm for the first time after reading different threads on this site and I think it works better than the chamois butt'r (and is way cheeper) that said I think any ride that goes over an hour there is a must use something need to be addressed. So give it all a try and use what works best for you. But do give bag balm a try. I know it works wonders for diaper rash. Hears to a comfy back side.
