as it gets colder out, i'm considering buying some cycling pants to wear instead of the nylon hiking pants i normally wear when commuting. (and no, i don't want to wear just tights when arriving at work) i'm looking for something that will help keep me warm and comfortable in the 15-40°F range, adding thermal tights as needed.

I tried on a pair by endura which seemed quite nice. it was nice to wear pants made for cycling.

Any advice on cycling pants for commuting in cold weather?
