Familiarity: I've used it several times
My daughter gave me this jacket for my birthday. Thought the silver color would look good on me, and it fit a gap between my down sweater, and my big-boy down. As a styler, it's great. Looks good, light, way comfortable, etc. Thought it was destined to become a work jacket. That's till it got good and cold, and I tried it out as a running jacket.
Well, ran at 2-below this morning, with a silkweight Cap t-shirt and this jacket. It is a wonderful, cold-weather running piece, but you need very little beneath. I wear the hood over a thin skull-cap-like beanie (top of the hood fits right behind my headlamp, and stays there), and can slide it back when the soft, winter sunrise brings some warmth. It handles wind well, vents easily, but does not move internal moisture well at all. Thus, dress light underneath. You'll be plenty warm for a 2 to 3 hour run, then you can shower and wear it to work.
This is a great jacket. Wear, and gear.
