Which jacket ? for casual town wear or short hill walk; Light < 16 oz. wind resistant, rain resistant, flexible, looks good for town

http://www.arcteryx.com/product.aspx?EN/Gamma-MX-Jacket The Gamma MX by Arc'teryx is bomber. I've used it for traveling mostly when I want something with a lot of pockets, hand warmer pockets, full front zip, water resistant (DWR), wind blocking. I have the hooded version though, which I can admit I'd rather have done without. Expensive option, but perhaps ebay? Friend with a pro deal?

The North Face Geosphere jacket may fit the bill, though I'm usually partial to Patagonia. I'd take it out for a half day hike, snowshoe, whatever … just a tad heavier at 18 oz but it was on sale ($75 USD).

Did OK worn in light blowing snow around Albuquerque and Santa Fe.

I'd second the Arc'Teryx Gamma MX. I have the hoodless version and pretty much wear it 24/7 once the temps dip below 70F and it usually suffices to somewhere in the 40s for me (I run cold being used to triple digit temps 1/3 of the year).

The hoody runs down to your hips and provides more coverage. the Jacket just comes down to the waist, although around town I've never noticed an issue with it. While the fit looks athletic it still has a deceptive amount of room for a thin midlayer or two under it (or maybe I'm just rail thin).

You may be able to find last year's model on sale somewhere (they refresh the design every 3 years or so, although don't change much really).

Again, I love mine and it's my go to jacket for cooler weather that isn't a tempest.
