Here is a very usable gear list that(with similar gear) has worked for me comfortably without a sleepingbag down to 45 degrees and if I want to go 35-40 (or extreme of 30 with assistance of leaves for bottom insulation) I add in that top bag.
It was designed by me, for long distance, weekend fastpacks. We are talking 40mile days here. so I found some of the lightest gear including a pack with a minimal hipbelt for some running on the trails.
