Specific sleeping bag recommendations

I’ve searched the sub and couldn’t find the info I seek, hopefully the hive can help me. I need sleeping bag recommendations with some particular characteristics. We car/canoe camp, so weight/packed size aren’t important. Budget isn’t a big concern, cheaper is always better, but I’d love if I could get it from Amazon. My goal is to find the right bag for me, spend whatever it takes, and not have to deal with it for 20 years.

I’ve listed the characteristics in order of importance to me

1. I’m 6’ tall, 230. Not a huge guy but most sleeping bags feel too snug/constricting. I understand that keeping it small helps keep warm, but I want something more roomy than average.

2. I’ve slept nude for 20 years and my current mummy bag feels like I’m sleeping in a Walmart bag. Even when I put on pjs, the material feels clammy and weird. I guess I’m looking at flannel? Open to suggestions on this for sure.

3. Temp rating. We don’t camp in winter, but I use a sheet and wool blanket most of the summer, so the bag is backup for nights that get colder.

4. Decent zippers. I don’t want to feel like Forrest Gump every time I try to get in/out of the bag.

Thanks in advance for your suggestions!
