I’m doing an overnight hike this weekend. Bush camping where there might be a frost.
I have a minus 6 comfort quilt and a R4 mat (and thermals and a hat to sleep in),
Am also considering getting one of the Thermolite reactor sleeping bag liners - which say they can increase warmth by up to 8, 11 or 15 degrees depending on the model.
Weight is 250g approx up to 400g.
What do you think?
