Today we open the 21th door, and learn about Gore Tex and get information about some new gear.

Gore Tex was founded as a trademark in 1976. In 1980 it was introduced to the Swedish market as a breathable rain suit clothing.

The product let the heat/sweat out. But the membrane pores is 20 000 smaller then a rain drop, so it keep the rain outside. The product is divided into three different quality.

Clothing with 3-layer Qualities has a membrane that is laminated on the inside of the outer material. Deep down, the body is a layer of mesh, which is also laminated to the other two bearings, which protects the membrane and provides extra durability.

In clothes with a 2.5-layer quality mesh lining replaced by a surface treatment of the inside of the membrane. It provides slightly less durability, but a jacket with low weight and low packing volume.

In clothes with 2-layer quality outer material and the membrane laminated together. On the inside is loose mesh lining. The loose lining wicks moisture away from the body, protects the membrane and builds up an air pocket that ensures that the jacket is perceived as a softer coat than with the 3-layer quality.

My experience is that 3 layers will have a longer life span, but the 2 layer will be more smoother. From a environment point of view, the material in Gore Tex will affect the nature, due to it is not degradable. So you have to consider that. Maybe you don’t need a new jacket just for the color due to that fact..On the other hand I would not go to the mountain environment without my Gore Tex clothes..

I will use my Gore Tex on the mountain, but will rethink when buying a new one..
