防风性能看面料透气率（CFM值），CFM<5为完全防风（如Gore Windstopper），CFM 5-15为软壳类高弹防风兼顾透气，日常城市通勤选CFM 10-30更舒适，纯防风闷热

Unverified防风性看面料透气率（CFM值），软壳裤防风级CFM应＜10，纯防风膜可达CFM≈0但透气极差；日常防风徒步选CFM 5-20兼顾透气90% similarUnverified面料抗风性看透气率（CFM），防风马甲应≤10 CFM，接近0 CFM完全挡风但透气差；20-40 CFM属通风款只适合微风86% similarUnverified透气性看CFM（气流通过量）参数：接近0CFM为全防风（如Gore Windstopper），40-60CFM为高透气通气型；大运动量选高CFM，静态防风选低CFM84% similarUnverified防风与透气本质矛盾：CFM越低越挡风但闷热，CFM越高越透气但防风衰减，通勤日常CFM 10-20兼顾，专业防风选CFM<583% similarUnverified面料防风性能通常用CFM（每分钟每平方英尺透气立方英尺数）衡量，CFM＜1为完全防风，1-5为高防风，＞20则基本不防风83% similar
