I have used a shell the past 15 years. This is good to temperatures in the teens (deg F) with some layers. Single digit F and lower and I will need to go inside periodically. I dress so that I am cold on the lift since I get pretty warm once I start skiing. If I get too hot, my feet swell and the boots get very uncomfortable. So skiing while warm is not possible - I err on the side of being too cold instead. It's easy for me to warm up by just skiing harder/more. Any problem that is solved by skiing more is ideal to me
The best 'knobs' I have to turn for clothing on mountain:
- Zippers in jacket/pants
- Helmet vent
- Balaclava
I ski primarily in CO or UT. My metabolism is pretty high, so that's definitely a factor. If I ski with a group that likes to stand and chat a lot (lessons, wife), I tend to get colder. I will wear extra on those days.
