Look at the sun protection standard
Textile ultraviolet protection coefficient UPF>50, and UVA (long wave ultraviolet) transmittance is less than 5%, can be called anti-ultraviolet product, but if the UPF is marked as 30+, it can only indicate that the clothing has a certain sun protection function, but It cannot be called sunscreen clothing. Moreover, the labels of regular anti-ultraviolet products should be marked with the national standard number and UPF value.
Look at workmanship
In addition to sun protection, skin trench coats must also be wind and waterproof, so workmanship is very important. The fabric is good but the stitching is not tight and meticulous, the zipper will break after being used several times, or there will be threads everywhere, which will cause air and water leakage. Therefore, after determining the sun protection standard of the fabric, you must carefully look at the workmanship, carefully check the joints of the seams and whether the zipper is good, and strive to make the stitches and zipper parts of the clothes meticulous and flawless.
Skin trench coat is called "skin" trench coat, the most basic concept is that it is light and thin, as light as a layer of skin. Therefore, under the premise of meeting the functional indicators, the lighter the skin windbreaker, the better.
