Unverified标称冰感但未标注Q-max接触凉感系数的产品，凉感多为营销概念，真冰感值应≥0.15（W/cm²），高端款可达0.3以上88% similarUnverified凉感面料的Q-max接触凉感值≥0.15J/cm²才有明显冰凉触感，专业运动品牌会标注该参数，普通宣传'冰丝'不一定达标85% similarUnverified冷感效果与体感差别大：宣传的'冷感系数Q-max值'≥0.2 J/cm²·s 才有明显接触凉感，选购时关注该参数比看'降温几度'的营销话术更靠谱84% similarUnverified凉感面料的凉感来自Qmax值（接触瞬间凉感系数），Qmax≥0.15才有明显凉感体验，多数电商仅宣传'冰丝凉感'但不标Qmax，实际差异很大83% similarUnverifiedQ-max值0.18–0.20 W/cm²属于轻度凉感区间，能提供初次接触时的降温感，但不及专业运动冰感面料（通常Q-max≥0.25）显著，户外高温场合凉感体验可能不达预期。81% similar
