In March of Yangchun, when we are doing outdoor activities, we often encounter rain. Therefore, when we travel outdoors, waterproof tents are a necessary tool. So you know how to understand the waterproofing coefficient, Xiaobian will explain it for you.

　　Waterproof tent as a waterproof tool, it also has waterproof coefficient, its waterproof strength and waterproof coefficient are closely related. The waterproofing coefficient refers to the millimeter water column pressure. The usual explanation is that when the 10000mm high water column is pressed on the fabric and the water seepage from the fabric does not exceed 3 drops in 24 hours, the waterproofing coefficient of this outdoor equipment can be determined to be 10000mm. And when it comes to waterproof tents, their waterproof coefficients are relatively high, and they are very used for outdoor waterproof.
