Sometimes, as a consumer, you may be confused about the water-resistant and waterproof features of your apparel and footwear. Simply say, waterproof is a higher level of water-resistant performance that blocks water from wetting your skin under the protection of the clothing while water-resistant is the ability to resist the penetration of water to some extent but it is not entirely waterproof.
In the demanding active sportswear market, waterproof breathable textiles are becoming more popular. According to Grand View Research, the Global Waterproof Breathable Textiles Market will reach US$2.31 billion by 2024. Various active sportswear applications, government support for research on waterproof breathable textiles, and high commercial standards are opening a gateway of opportunities in the global textile market.

Frequently Asked Question
What is the difference between waterproof, water resistance and water repellency of textiles and footwear?
Water-repellent feature means the product is not easily penetrated by water, which is usually treated with a surface coating making it hydrophobic.
Water-resistant feature is the ability to resist the penetration of water to some extent but it is not entirely waterproof. It is the capability of product to withstand the average hand-washing or light rain shower.
Waterproof feature means the product is capable to be impervious to water even under heavy rain so that no water gets inside.
