I'm looking for recommendations for a decent raincoat. I can't decide between a car length coat or a real single-breasted trench style. I would really love the Brooks Brothers golden fleece single breasted raincoat, but it's 800 bucks (-25% currently). This seems to be a steep price to pay for something that will be worn mostly dashing from building to building. Do you find a car length coat adequate (just covers the suit by about 4 inches) or not? How much would you pay for one? thanks.
