I will add my vote to the Western Mountaineering camp.

I am a side sleeper also and sleep really cold these days.

I have 3 of their bags.

The first one I bought was their Antelope model in their old Dryloft configuration.
I used it wide open in the summer to below zero with strong winds with me wearing all my clothes it has kept me comfortable.

The next bag I bought of theirs is the Caribou. It packs down small and makes a nice summer bag. The microfiber shell beads water off of it nicely from condensation that formed on the walls of my TarpTent.

My favorite bag though is their Alpinlite which I bought last fall. The extra width just makes it comfortable and it packs down small and really lofts up nice. I have used in an open lean to 20 Degrees again with my clothes on, no problem.
It will be my go to bag from this point on.

My buddy uses Mountain Hardware Lumina bags and he has climbed all over the world. If you are looking into synthetic bags that might be a good place for you to start as he is around your size.
