Alright, so I'm not spending 24 hours a day hanging over a precipice. Still, I bought this to keep me warm in winter, and it definitely does that very well. I've had a POLARTEC 300 fleece for over 10 years before and that's why I decided to go for another - keeps you warm, doesn't overheat (you can wear them comfortably when it's 50 outside and it doesn't feel too hot) and nothing beats the weight (at least nothing normally accessible).
When I got this jacket I was a little surprised by the extra fabric on the top front part (which gives it that two-color look), but I actually like the idea - I suppose might make it a little more durable there. Combined with my old shell, this outfit got me through the worst winter in the last 7 years without breaking a sweat - 0 temperatures (-20 with wind chill factor) but inside the jacket and shell, feels like home.
Considering that my last POLARTEC fleece (although looks really bad) is still usable (after those 10+ years), I expect no less from this one - so this comes out something like $10 - $15 / winter - not bad I'd say.
