What does a three - proof hard - shell jacket protect against?
The "three - proof" of a three - proof hard - shell jacket usually refers to water - proofing, wind - proofing, and stain - resistance:
Water - proofing: The outer layer of a hard - shell jacket generally uses a water - repellent coating or a high - density fabric, which can effectively block the penetration of rainwater and other moisture, ensuring that the wearer stays dry in rainy or wet environments. For example, when hiking in the rain, it can prevent the clothes from getting wet.
Wind - proofing: The outer layer often uses materials such as polyester or nylon, which can effectively block the flow of outside air, reduce wind resistance, and prevent the wind from directly contacting the body, maintaining the body's heat. In cold and windy weather, the wearer will not feel cold due to the wind.
Stain - resistance: Due to its water - proof and wind - proof properties, a hard - shell jacket can prevent stains from adhering to a certain extent. In addition, the inner - layer fabric often has wrinkle - resistance, allowing the wearer to stay tidy. For instance, if you accidentally rub against something dirty outdoors, the stains are not likely to penetrate and remain.
