For those who love outdoor sports, the jacket is one of the indispensable equipment. Whether it is mountaineering, skiing or rock climbing, the jacket can come in handy. Perhaps many people will feel confused, why the function of the jacket is so great, this is attributed to the role of jacket fabric.
No matter what kind of jacket is customized, waterproof and breathability is the key to its choice of fabric. From the perspective of fabric and production, the jacket has RET index evaluation: Ret value is between 0 and 6, which means good breathability; Ret A value between 6 and 13 means good air permeability; a Ret value between 13 and 20 means normal air permeability; a Ret value above 20 means poor air permeability. Breathability refers to the speed at which water vapor molecules penetrate the clothing layer.
Another criterion for choosing a good jacket for customization is to look at its fabric. The fabric of a jacket is generally divided into an outer protective layer, a middle waterproof and breathable layer and a lining. The protective layer and the waterproof and breathable layer are pressed together, and the lining is separated from them, usually nylon silk, mesh cloth or some kind of sweat-absorbing material, mostly black. The rubber strip at the seam is blocked by the lining and cannot be seen.
Three-layer fabric: the protective layer, the waterproof and breathable layer and the lining are pressed together, which looks like a layer of fabric. Generally, the color of the lining is mostly silver-gray. You can see the tape at the seam of the lining. Generally speaking, the breathability and warmth of the two-layer fabric is slightly better than that of the three-layer fabric, but the three-layer fabric is lighter in weight, comfortable to wear (the second layer is a bit wacky), and the folding volume is small (the jackets of spring, summer and autumn are mostly put In the bag). So unless you only consider using it in winter or snowy mountains, it is generally better to choose a three-layer fabric.
