凉感系数越高通常纤维越紧密光滑，透气性和吸湿性越差；追求极致凉感（Q-max≥0.4）会牺牲透气性导致闷汗，日常Q-max 0.2-0.3更平衡

Unverified凉感值Q-max越高触感越凉，但高凉感纤维通常导热快、在无风高湿环境下凉感反而消退更快且不吸汗，闷热潮湿地区应优先透气排汗而非单看凉感数值89% similarUnverified凉感值Q-max越高的面料往往越密实光滑，透气性反而越差，闷热出汗后凉感失效更快；追求长时间户外可选凉感中等但透气好的针织款87% similarUnverified凉感（Q-max值）越高越冰爽但与透气排汗往往冲突：高凉感依赖锦纶/尼龙冰丝面料，吸湿排汗差，闷汗后反而黏腻；纯户外运动大量出汗场景应优先选透气排汗，凉感为辅85% similarUnverified凉感（接触瞬间凉）与真透气是两回事：凉感来自纤维导热系数（Q-max值≥0.15J/cm²·s），但闷不闷取决于透气排湿，凉感款若不透气反而闷汗，需两者兼看85% similarUnverified凉感强的化纤材质（如聚乙烯冷感纱、尼龙冷感）Q-MAX高但吸湿性差，出汗多的人易黏腻闷汗；天丝/莱赛尔吸湿透气但Q-MAX通常0.15-0.25偏中等，出汗多者优先选天丝而非纯化纤凉感84% similar
