What is GORE-TEX®?


GORE-TEX® is a synthetic fabric used in a wide range of outdoor and sports clothing. It is similar to nylon in that it is tough, lightweight and waterproof but where it differs is its ability to be permeable to air and water vapour. Basically, it lets sweat escape out through material as water vapour but doesn't any rain water in to maintain its waterproof properties. This makes Gore Tex® a very useful clothing fabric for people who work outdoors and those who are involved in a variety of outdoor activities.

GORE-TEX® contains a polymer called polytetrafluoroethene (PTFE) (otherwise known as Teflon®) which you would find on a number of household products such as non-stick cooking pans, tennis racquets and a whole host of other decorating and recreational items. Each square millimetre of PTFE contains millions of tiny holes called pores each of which are too small to allow water to pass through, but big enough to allow the smaller water molecules created by sweat to escape.

PTFE is then combined with the more durable properties of nylon and polyurethane to create the completed GORE-TEX® synthetic fabric.

Enhanced GORE-TEX® Testing

Each GORE-TEX® clothing product is rigorously tested through a variety of methods to ensure that the garments are as durable, protective and breathable that they need to be. Testing involves:
