Fill power, briefly
Fill power is how much space an ounce of down fills. Higher numbers mean less down for the same warmth, so a lighter, more compressible quilt at a higher price. Warmth still depends on how much down there is, so compare total weights, not just fill power.

Add any of these to your pack and track base weight, total weight, and cost as you go.
