In recent years, outdoor sports such as mountaineering, skiing, rock climbing, and camping have become popular among the public. Waterproof fabrics are the first line of protection against the alpine climate with significant temperature changes. It can keep the wearer dry and comfortable even in wet conditions.

Applications for Waterproof Fabric include outdoor sports apparel, footwear, bags, military apparel, and protective apparel. According to the statistics of the United States in 2019, it is estimated that the population over the age of 6 goes out nearly 75 times per person; about 20% of the people participate in outdoor activities at least twice a week.

Waterproof fabrics play a vital role so that the wearer can still feel comfortable when they are active outdoors in wet conditions and avoid the cold and wet feeling caused by sweat on the skin. 

The common microporous on the market are hydrophobic materials. The material has countless small holes invisible to the naked eye, smaller than water molecules but larger than water vapor molecules. Thus, they can prevent water molecules from entering but allow water vapor molecules to pass through. The hydrophilic glue has no holes to directly block water penetration into the garment, absorbing the moisture emitted by the skin through the hydrophilic material. It then evaporates into the environment.Microporous Fabric plus waterproof and permeable layer we call 2 layers, and 2.5 layers will be printed on the back (coating surface or lamination surface) pattern. Of course, you can also do three-dimensional printing to avoid the uncomfortable feeling of the fabric sticking to the skin when sweating. The third layer is to add knit fabric outside the waterproof and breathable layer.
