But you've torn it...so need something heavier?

I'm a lot like Meg with respect to the cold; I don't function well when cold. Very cold and I don't function at all.
The older I've got the more difficult I find it. So I'm looking around at what people who live in the cold wear. Search on the Internet and you get endless recommendations for smart lets go skiing, or hiking type stuff. I've had some of that and at the prices I can afford it's crap basically.
