“But what about the summer? Michigan summers can get pretty warm and humid”

My favorite summer bag is the western mountaineering caribou (35F); weighs 20oz. It can unzip fully which is much appreciated. And you don’t have to worry about down shifting. It stays in place. I love box stitched down bags.

If I know it’s not going below 70F, I take a cotton liner only (oh no! cotton!). This is about the only time I take cotton because when I have a heavy sweating day, I’d rather lay on cotton than nylon or silk.

Also consider the 15oz down quilt from Jacks R Better or a synthetic 14oz ‘Backpacking Light PRO 90 Quilt’

It’s not worth carrying heavy sleeping gear in the warm summer.
