Since the skiing season is on its way here in the States i decided to start a thread for people who haven't been on a ski trip. I personally haven't been and i am wondering what kind of clothing to pack other than "warm clothes".
Jackets, goose down, base layer, pants? I haven't got a clue.
You want to dress according to the weather, which, in the Rockies at least, can change throughout the day. Nothing spoils a day on the slopes like being cold and knowing you have every warm article in your possession already on, or being too warm and not having an acceptable layer underneath if you need to shed. If you start sweating, you'll chill faster when the temperature drops. And although you may feel toasty around noon when the sun is high, in the late afternoon, it can get cold.
I would suggest a moisture-wicking base, long-sleeve t-shirt and (maybe, if you need the padding)sweats, your ski bib and a zip-up jacket like Jamie suggests, and a good pull-over shell. Rent a locker at the ski-lodge and shed as necessary throughout the day.
Most ski rental shops also rent ski bibs and shells, so take advantage of that if you want to pack lighter.
Make sure to bring plenty of socks. Wet socks can be unbearable, and bringing dry ones really doesn't take up too much space. Definitely have to be wool too. Cotton Athletic socks really do get wet (or sweaty depending on the temp) and they're not very good
I am also always reluctant to wear my down vest as outerwear skiing because of crashing; especially in areas where the slopes are icy. I think it's important to have your outerwear be durable enough to take a ride
