I went to xmas eve service in my kilt......mind you i was in bloomington Illinois at the time...14 F with windchill -5 and it got a little chilly...I was colder wearing running pants on my 4 mile run earlier that day.

I also went out for a night in Lo Do denver when it was 5 F with no problems and I'm an Arizona desert rat! just keep your upper body warm and the rest will follow suit. ( just warm up your hands before going to use the restroom)
