I live in Wisconsin and own the Sanctuary Suit. They are definitely warm. I’ve warn the jacket from 40- to the negatives and the bibs as well. Last year gun season was 30 degrees with wind, all I wore was a base layer, my normal hunting pants, and a light hoody and was plenty toasty. Again, pack most of it in. If I can get away with it, I’ll wear the bibs in and have just a base layer on on the walk in. Sides of the bibs wide open. Late season I can usually do the same with one extra layer on top. Honestly it’s like wearing a big comfy sleeping bag, and it is dead quite. If I had to change one thing, I think it would be getting a Woodbury jacket, just because it would be much more versatile. Add a would layers underneath and you would be set. It’s definitely a sweet system. A lot of people say there’s not wind proofing, but I have yet to have wind effect me without proper layering.
