Packing as small as possible means high quality down. Comfort temp at 5 C should be fairly easy to find. I have a Mountain Equipment Helium 400 that packs down to almost nothing and has a comfort rating of 0C. You'll find lots of other brands with similar bags.

I'd second the Mountain Equipment Helium. Great kit and definitely a quality brand.
