On temps around 32* I'll start with a thin and heavier Kuiu Merino - maybe with a vest. If I get to a place that I'm going to spend time to glass, I'll replace that set without a dry set and put them in a plastic bag. Have done that many times and it just works for my style.
Below 0*, I'll do the same and add a lighter down jacket and peel and replace as needed.
But everyone is different. Good luck.
