The properties of our GORE-TEX® membrane at a glance:

* Durably waterproof
* Very breathable
* Highly cold resistant
* Extremely light
* Resistent to flexing
* Blue outer shell
* Detachable fleece

The secret of GORE-TEX® fabrics lies within its revolutionary bi-component membrane.

The expanded PTFE portion of the membrane contains over 9 billion microscopic pores per square inch. These pores are approximately 20,000 times smaller than a drop of water, but 700 times bigger than a molecule of moisture vapour. So whilst water droplets cannot penetrate the GORE-TEX® membrane, moisture vapour (a gas) can easily escape.

Integrated into the ePTFE structure is an oleophobic, or oil hating substance that allows moisture vapour to pass through, but creates a physical barrier to contaminating substances such as oils, cosmetics, insect repellents and food substances.

The result is a totally waterproof, windproof and breathable membrane.
