When you are inside a sleeping bag in a hammock, your weight compresses the loft of the bag against the hammock itself, thus creating cold spots. To make up for this, you can use pads (ccf usually) in layers to help build up more insulation beneath you. A popular option for hammocks, though, has been to move away from typical bags and to use uderquilts that are suspended with the hammock itself. Because they are outside of the hammock itself, you get the benefit of their loft not being compressed and so they retain a larger amount of their insulating properties than a typical bag. Additionally, some people actually use down hammocks which actually have the quilt-loft sewn into the bottom of the hammock itself. Mind that there are a multitude of options for bottom insulation, and everyone seems to have their own preference. But, in general, using underquilts/topquilts/pads seems to be the most popular.
