Gore-Tex is a proprietary teflonized textile material owned by W.L. Gore & Associates. It has the property that water vapor in the air may pass through its pores, but liquid water may not; commonly said to be 'breathable'.

It is used in a huge variety of applications, from lining walking boots to bags for bagpipes.

The first commercial Gore-Tex product was a tent called the Light Dimension that was created and sold by the Seattle firm, Early Winters, Ltd., in 1976.
