The principle of windproof pants is to use high-density knitted composite fabric, which is thick and impervious to cold air, and with nano-coating, the strong windshield can be placed outside the legs.

In addition to wind protection, the fabric of the trousers is also treated by DWR, and the surface forms a water repellent layer, which can be waterproof. Like a lotus leaf, the water drops are "shut out" and the water flows away directly, so that the cloth will not be soaked at all. Rain and snow really need a pair of hard-core waterproof and windproof pants. They won't get wet by rain and snow, and the cold wind can't blow in. In reality, the "King Kong iron cloth shirt" is windproof pants.
