Here is my winter kit, which I use for multi-day ski mountaineering trips. I've stripped out all the ski gear and its weight from the list for you. I've used this exact setup on many trips in the Sierra Nevada Range, the Cascades, and on Mount Shasta. If you are expecting colder temps, then I would recommend maybe a warmer puffy jacket and pants. I love my Black Diamond tent and have zero problems or complaints with it in the snow. I find that in the winter I absolutely have to have a pack with a frame, as I'm always carrying skis, crampons, skins, harness, etc. and a frameless pack just can't do the job. The Atmos 58 is the best pack I've found so far.
All in all, this is a perfect balance of comfort, weight and security for me. I could get down to a pound or two less by using down, but I prefer the assurance of synthetic loft.
