透气性与防水性此消彼长：透气用MVTR值衡量，≥15000g/m²/24h为高透气；20000mm以上高防水膜（如硬壳）透气普遍偏弱，长时间快走易内部凝水，压缩款优先选透气膜（如三层软壳/2.5层轻量膜）

Unverified透气透湿性用MVTR（水蒸气透过率）衡量，薄膜敷料MVTR通常500-800g/m²/24h适合低渗液，泡沫敷料可达2000-3000g/m²/24h更适合渗液创面防止浸渍84% similarUnverifiedTPU防水膜透湿量普遍达3000-5000g/㎡/24h，远优于PVC(几乎不透湿)，是可透气防水垫的主流材料标准81% similarUnverified防水袜的透气性靠薄膜的MVTR值（透湿量）衡量，优质薄膜MVTR≥10000g/m²/24h。低价防水袜常用不透气的PU薄膜，短时防水但闷汗，穿1小时内部因汗水积聚即湿透，长距离运动反而更难受81% similarUnverified透气性看透湿量MVTR：单纯膜(如DryVent)约10000-15000g，Gore-Tex/eVent膜可达20000g以上，剧烈爬升出汗多的人应选透湿量≥15000g并带侧向拉链透气口81% similarUnverified护垫底层膜的透气性以透湿量(g/m²/24h)衡量，日常使用应选打孔膜或无纺布透气底层（透湿量≥2000），全PE不透气膜会使会阴部湿度和温度升高，助长厌氧菌繁殖81% similar
