面料越轻薄透气性越好但防风性越差，20D以下面料在5级以上大风环境需搭配防风外壳，纯超轻款不适合作为最外层抗风

Unverified防风性能看面料密度而非厚度，高密度平织尼龙（如20D以上高支）比松散棉质更防风，即使更薄；棉质薄夹克几乎不防风83% similarUnverified防风外套看面料纱线密度，尼龙面料标注20D-40D轻薄但防风一般，70D以上防风抗撕裂明显更好但偏重81% similarUnverified抓绒衣本身几乎不防风，普通抓绒在4级以上风中保暖大打折扣；需防风应选带Windstopper/Windpro膜层的抓绒或外搭硬壳，但复合防风抓绒的透气性和压缩性会明显下降81% similarUnverified面料防风性看密度而非厚度：高密尼龙/涤纶（400T以上）风阻性能优于同重量的疏松梭织棉，薄款风衣也可有效挡风80% similarUnverified轻量羽绒服普遍牺牲防风性换取轻薄：7D-15D超薄面料抗风能力弱，无风情况下保暖但遇大风体感骤降，风大地区应选带DWR涂层+较高织密度款80% similar
