鹅绒与鸭绒在同等蓬松度下保暖性差异不大，蓬松度（FP）才是决定保暖的核心指标；鹅绒仅在能做到更高FP和更少异味上有优势，不必为'鹅绒'标签多付溢价

Unverified鹅绒的蓬松度上限和保暖回弹性通常优于鸭绒，但同蓬松度下二者保暖差异不大，鸭绒性价比更高；预算有限时选高蓬松度鸭绒优于低蓬松度鹅绒80% similarUnverified蓬松度（FP）比含绒量更能反映保暖效率：同样充绒量下，900蓬的羽绒服比600蓬更轻更暖，因为高蓬绒朵大、储存静止空气多75% similarUnverified在同等价位下，ThermoBall Eco 的保暖效率低于同克重优质鹅绒/鸭绒，如果首要需求是极寒保暖而非防潮，应优先考虑高充绒量羽绒款。74% similarUnverified蓬松度越高保暖越好且越轻越可压缩，但同等充绒量下高蓬松（800+）内胆保暖后劲不如厚重的低蓬松加大充绒量款，作为纯内层保暖优先选高蓬松以减少体积72% similar
