Thanks to the distinctive structure of its material, air-permeable ePTFE (expanded polytetrafluoroethylene) material achieves an exceptional balance between breathable and protective. Not only does this material "breathe" in the sense that water vapor molecules can pass through it, but it also appropriately protects against nature's aggressions during extreme conditions, such as rain, wind and extreme temperatures.

The ideal choice for many applications because of its advantages, ePTFE (expanded polytetrafluoroethylene) material. ePTFE material has a microporous structure that lets water vapor molecules through, but not larger liquid water. This ensures them as comfortables especially while doing the outdoor activities or sports and aids in keeping the skin dry. The function of being waterproofing that is gained through ePTFE material, makes it a favourite for making raincoats, tents and other outdoor equipment. It can keep rain from passing through throughout while sweat would evaporate keeping the inside dryer.
