随着户外运动的普及，在冬天穿冲锋衣的朋友越来越多。
冲锋衣原本是：为了适应户外极端天气而设计的功能性服装，重要的3个功能：防风，防雨和透气。
很多朋友会问：既防水又透气？这不是矛盾吗？
就像塑料袋：防水了就不透气。随着科技的发展，现在已经可以通过在布料背面附着不同的涂层或者复合防水膜，来达到上述的功能：

At present, the generally recognized waterproof layers are divided into four generations: <br /
第一代：早为了达到防水、防风的效果，只是在面料上刷了防水胶，以达到防水目的，这种材料和工艺制作的产品，可以耐一定的水压，但透气性相对差。而且由于涂层工艺的不稳定性，涂层容易剥落。防水效果不稳定。
<br /
Second generation: PU film, which is a material with good water pressure resistance. When the product fabric is combined with it, it can achieve better waterproof stability. Its high-end products may have some moisture permeability, but the effect is very poor. ideal �如：市场现有KING-TEX� �<br /
<br /
The third generation: TPU film, developed on the basis of PU film, is better than PU film in terms of air permeability, moisture permeability, and water pressure resistance. It is a waterproof and breathable film that replaces PU film. Domestic products include TING-TEX, KING -TEX etc. �<br /
<br /
第四代：ePTFE（聚四氟乙烯）薄膜是新一代防水透气材料，世界一流厂商目前均采用。性能优异的主要有：GORE-TEX（美国戈尔公司研发，在各品牌高端产品线上使用）、OMNI-TECH（美国COLUMBIA公司研制，只在COLUMBIA品牌中使用）、TEXPORE（德国JACKWOLFSKIN公司研制，只供其自身品牌使用）、FIRST-TEX（U.S.A.THEFIRSTOUTDOORINC.国际集团研发，目前只用于THEFIRSTOUTDOOR/TFO品牌的防水系列鞋服产品）
</p
In addition, there is EVENT (developed by a professional waterproof and breathable material manufacturer that has rapidly emerged in recent years, and its waterproof membrane has been used by the US Marine Corps) <br /
上述企业，利用现代科技，进行复合处理，开发出各有特长，不同品牌的ePTFE复合面料，其防水透气性均是目前出色的。
现在高科技户外产品又与时尚充分结合，已经出现越来越多，既适合户外旅行又适应城市日常穿着的舒适产品� �让身穿第四代防水，专业户外冲锋衣的你，也可以很好的融入商务氛围�
