I left my rain gear in Florida, so I bought another set at the local bike shop, Joe Rockett, absolute junk, crap. My other set is Alpine or Aerostitch, I forget which, in 5 minutes I had a hole burnt through the "heat shield" on the right leg, in 10 minutes 3 holes. I've never burnt jeans, my other rainsuit is 7 or 8 years old, no holes. Wouldn't you think if you were putting a heat shield on pants, you would use something that was at least a little heat resistant? Apparently less heat resistant than cotton, think about it.
