Unverified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83% similarUnverified防风与透气不可兼得：防风指数（CFM）越低越挡风但越闷，跑步选CFM 20-40的半防风款，逆风骑行/滑雪才需CFM＜10的全防风款83% similarUnverified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80% 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CFM80% similarUnverified防风面料越致密（CFM越低）越挡风，但透气性和轻量化越差；追求极致防风会牺牲运动排汗，多数运动场景选10-20 CFM兼顾更实用80% similar
