The zero-G fabric is crafted using a proprietary membrane technology, which involves laminating dozens of PTFE film layers. Its core lies in a unique spider-web-like microstructure. During the membrane manufacturing process, synchronous stretching in both longitudinal and transverse directions creates bacterium-filtering grade pore channels with a size of 0.2 μm, resulting in a distribution of over 10 billion high-density micro-pores per square centimeter. This enables the fabric to achieve excellent down-proof performance and a extremly air permeable experience.
