As it happened, ePTFE material has controlled porosity (thousands of holes not visible to the naked eye), making the fabric 100% impervious to water at low pressure while also passing air molecules through. This quality makes it ideal for use in tents, gloves and uniforms where both breathability as well as waterproofness are desirable traits in outdoor equipment & clothes. Even better, ePTFE was able to compete at each end of the temperature range as well, with an impressive -240°C to +250°C service temperature range … thus excelling in extremely low temperatures or high-thermal extremes environments.

It is because ePTFE has a microporous structure that allows sweat vapor to evaporate away from the body while preventing external moisture from entering. This also creates a comfort feeling to the wearing person without leaving him/her moisty and suffocating along with sweat while performing on / during it. ePTFE material ensures that rain, snow or any other external moisture cannot penetrate into the inside of the clothing. This protective effect helps protect the wearer to stay dry and comfortable even in inclement weather.
