If the 层胶 is Gortex, it's supposed to be breathable. My ~20 years old Gortex coat(threw out yearsSS ago), I couldn't believe the 层胶 on the inside when I opened it up before putting into garbage. It looked almost like a layer of tar but was so light). I don't like the current Gortex, too think and doesn't look study. People say many other new material replaces Gortex but more reasonably priced.我想知道你的衣服是怎么实现透气却不透水的?我买两次防水的衣服,夹层里面有一层胶,出汗的时候明显水气闷在胶层里面。
