I'm planning a bit of a test tonight;
I have an old thermarest that I'm going to place inside of my Recon 3, Gen II -5C (20F) sleeping bag. Under that I have a 6mm (1/4) CCF pad.
To give me extra width around my wings, I've got a windshield heat visor tucked in between my sleeping bag, and the CCF pad.
Even though I'm going to give it a go (I'm not planning on sleeping in it tonight. Just a quick 30 minute lay before I retire to my indoors bed), I'm wondering if anyone else has tried something similar to this & with what results?
