Air is a pretty good insulator. The insulating properties of your fiberglass mat home insulation, the down in your sleeping bag, the foam in your cooler and the thinsulate in your ski suit are all attributable mainly to the trapped air. The solid material provides loft to maximize the volume of the trapped air, and baffling to stop the air from circulating via convection. The thermal conductivity of air is less than the majority of solid materials. The insulating ability of a most common insulation materials is more or less proportional to the ratio of empty space to solid material. Down is such an effective insulator because the quasi-fractal structure of the little branching feathers means that a small amount of solid material can puff out a lot of volume and provide very effective baffling.
