I also bought pants, was at a bike show last winter and tried on chaps 1st. but once I tried on the pants I was sold for all the same reasons as chasarms post. I've worn them many days with no regrets.
I have both. I haven't worn my chaps since I bought my leather "overpants", with full length zippers in each leg. In warmer weather, I wear shorts under them. Got them at Jafrum.com, less than a $100 good thick leather.
I was listening to Brandmier on the ride to work. They were talking about flight attendants. They have a term called "crop dusting" which translates to them moving down the aisle while farting. The movement spreads it out; avoids hot spots and hides who did it.
