Last year I bought three different insulated jackets (Steep and Cheap just kept offering them up, yes, and I have since signed up with a 12-step gear addiction program)
I love the
lightest jacket of the bunch, but I haven't used it in the mountains yet, It is light and warm, but no hood and really too thin for anything but summer, I think, unless you also bring a fleece to layer with it. It is super light and packs into its own pocket, making it a standard gear item for summer trips.
My redneck office mate said I look like a girl from New Jersey when wearing it... Mine is last year's model, 800 fill, all shiny black, but I got it for less than $100.
For possibly wet and overall not so friendly weather I have a Mammut Stratus synthetic fill belay jacket with hood (also a Steep and cheap steal at about $100). I would probably take this one on a longer ski tour - the risk of down getting wet has me somewhat worried when heading into place where I cannot back out for days when things turn ugly. A bit heavier than your usual down jacket for its level of insulation, but still well under 2 pounds.

Just thin enough to still fit below my hardshell, but seriously puffy when worn alone. It's warmer than the Mammut, not much heavier, and has a conduit fabric layer to help keep things dry. I have not had a chance to test how well that actually works.

Great on those cold Whitney mornings in early April when your Jetboil Helios pot lid takes a frisbee flight down the mountain and you have to get out of the tent to retrieve it from the frozen surface of Frog Pond, 400 feet below:
When shopping for the warm jacket, I was initially looking at the Western Mountaineering Flight jacket (now called the Meltdown Jacket), but it seemed rather expensive for the 6 ounces I could have saved, and the Flight jacket didn't even have a hood. Even the the Patagonia Fitzroy seemed like a better choice at the time, but when the MHW went on sale ($139, I think), I grabbed it. Like it a lot, even if it's just 650 fill - that kep the price down. It's twice as heavy as the North Face Diez but also much warmer.
