Using an Exped downmat 9 with a WBRR

[Slowski]

I am thinking of using my Exped downmat 9 with my WBRR for winter camping. Does anyone have any experence with this setup?

Warmth is good at least for -30 C (-22F) with good sleeping bag. CSS is probably not a problem with WBRR.

(I have Synmat 9 LW version and had zero problems with -29C)

Thanks for the reply voivalin. I am going to give it a test when the temperature drops below freezing, in my backyard of course.
