BMo3: I just got this in the mail today (in the blue color).

I love it. It's heavier than I thought it would be but will be good for when it gets in the 20s but not so heavy that I'll sweat too much. It has vents on the front of the shoulders and in the back. And the sleeves zip off. And...it has reflective piping for those winter evening runs. I suspect it'll also get used quite a bit for XC skiing.

Have you found your perfect jacket/vest yet?
