I have artic Carhartts. Got them at Rural King. Like the fact they have zippers down both lets. Got them extra long so when I'm sitting on a tractor my legs are covered. They were good for cold weather riding on my Goldwing. No longer have the wing.
That said, I like layers of clothes better. It may be freezing in the morning. As the day goes buy, I'm removing layers to keep from sweating. Then I have a cab full of clothes.
