I'm looking to upgrade my weather gear setup and looking for some advice. This setup will be used for low 20's to 40's temperatures. I'll be using a 150 merino base layer and then maybe the first lite furnace. Question is for bibs, first lite sanctuary or solitude. For tops, I'm using a 200 merino base layer and then a 260 merino base layer, then the sitka equinox hoodie. I do have the first lite solitude vest but don't think that would be enough. I am looking at the sitka fanatic vest or the first lite solitude jacket. Thoughts?
