Greetings all. I’ve been reading, following, and gaining valuable knowledge for years from these forums but this is my first post. I’ve searched high and low but I can’t find an answer to my question. I purchased the first lite sanctuary set 2 years ago for bowhunting in an effort to stay warm when the temps dip below freezing. I love the jacket for these conditions and will continue to use it for this application. Although much lighter and less bulky than cold weather clothing from Cabela’s, it is still somewhat heavy. I’ve been wanting a lighter weight setup for stand hunting in rifle season. I have my heart set on the first lite chamberlin down jacket at less than half the weight of the sanctuary. I know I am comparing 2 completely jackets intended for 2 entirely different purposes but my question is……how does the chamberlin compare to the sanctuary in terms of warmth? It is not extremely often but I have hunted days where highs were in the mid teens in rifle season and late season flintlock here in Northeast PA. Thank you in advance.
