I have a Pearl Izumi Zephhr (bright yellow) that I really like. It packs down to almost nothing and provides good wind breakage/moisture resistance across a wide temp range, depending on your base layers. They sell for less than $75--probably closer to $50 on Ebay. I'm thinking about getting one in another color for XC skiing. I don't want to head out into the woods in "don't flatten me, dude" yellow.
