Four-way stretch fabric - Four-way stretch fabrics have the ability to stretch both horizontally and vertically, allowing for greater range of motion and comfort. They are usually made of a combination of polyester and spandex or elastane. These fabrics are commonly used in outdoor gear such as sportswear, hiking pants and mountaineering clothing. Four-way stretch fabrics differ from other types of stretch fabrics, such as two-way or two-way stretch fabrics, because they provide more flexibility and freedom of movement in all directions.

Water repellency - The hydrophobic surface treatment (DWR or WR) of the fabric protects against soaking and pollution. If drops of water fall on the surface of the clothing, splash and then slide down the material, it means that your jacket or pants have a functional hydrophobic treatment - a water-repellent surface.

PFC free - Dirt and water-repellent impregnation without fluorocarbon compounds, the so-called PFC. Chemical compounds that are harmful to the environment and health are not released when worn or washed.

Water column 5,000mm - The water column expresses the waterproofness of functional clothing and its value is given in millimeters. According to the h value of the water column , you will find out how much volume (column) of water a particular fabric can withstand before water starts to seep through . If the water pressure exceeds the given limit, the fabric will start to seep water and become wet. The longer you move in a humid or wet environment, the more waterproof your clothing becomes. When buying clothing with a water column, it is good to consider the environment and how you will use the clothing.
