GORE-TEX® Guarantee of impermeability and breathability.

Bestard was the first Spanish brand, and one of the first in the world, to incorporate GORE-TEX® linings in mountain boots. Thanks to a close collaboration between W.L. Gore and Bestard over these 20 years, we have managed to manufacture boots that offer a unique combination of, on the one hand, durable waterproofing, and on the other, an effective evacuation of the moisture created within the boot.

The secret to achieving an optimal result lies in a difficult combination to achieve: on the one hand the use of the GORE-TEX® lining itself, and on the other the selection of materials with high performance features (leathers, fabrics, supports , sponges etc), as well as a careful and meticulous way of manufacturing the boot.

The GORE-TEX® lining is a system in itself, whose main part is a stretched PTFE membrane, whose surface consists of in millions of microscopic pores that gives it excellent breathability. The pores are large enough to allow vapor molecules that are created inside the boot (sweat) to pass through, but at the same time small enough to prevent water molecules from passing through (rain, snow ...), making it waterproof.

The complete lining is made up of different functional layers, which protect the membrane, contribute to a long duration of the inner lining, a good absorption and evacuation of sweat, etc ... Thanks to the different functional layers of the lining, there are different variants of GORE-TEX® lining, all waterproof and breathable.
