I agree. I think you will quikly overheat in that coat if you are doing much more than walking. Although not "trad," it is hard to beat The North Face for hiking type gear.I like the style, but not sure about that fabric. Have you owned any microfiber jackets or coats? Personally, I have found that they don't breathe, even with a natural fiber lining. Some coats like this do have a breathable fabric, but from the description I don't believe this one does. So, if you're hiking (read: exercising) I would be afraid that you'd begin to perspire in this one, with no place for that moisture to go.
