I already have a wool peacoat I have from the Navy (20 years old now!), but I need a ski jacket or waterproof/windproof jacket that I can wear for winter actvities.

I don't mind spending a little extra if the coat is truly warm, but I don't want to spend over $100 to find that out.

What materials really contribute to the coat's warmth and wind resistance?

Also, please let me know if any of you have such a jacket and what brand it is..

Thanks in advance! This website is the best when you need some good advice
