First report on stratos - this morning was 19F so not as cold as Monday. I wore same base layer but was much less sweaty. I also noticed I was a little colder but not uncomfortably so. The stratos does not block wind as well as the NF jacket, but the tradeoff seems worth it. I did not open the pit vents. I think erig007 is correct that this might be overkill and based on several suggestions from this and other threads I'm going to contact Foxwear today. However, I really like the stratos - it's a really nice jacket and since I got it relatively cheaply I'm going to keep it as a rain shell. The saga continues...
