This means that water in its liquid form is unable to pass to the inside of the membrane, but water as a moisture vapour from sweat is allowed to pass to the outside. This is when the membrane is bonded - or sandwiched together - with the main body fabric, usually a synthetic such as nylon. Gore-Tex comes in a range of fabric constructions, including three-layer constructions where the membrane is bonded to face fabrics on both sides , two-layer where the membrane is bonded to a face fabric on one side and can have a liner on the other, allowing the option for insulation , insulated and uninsulated.
Finally there is seam sealing. Sealed seams provide a waterproof jacket with complete weatherproofing and prevent it from leaking.
If you look inside most waterproof jackets you will see strips of tape which are used to seal any gaps that have been created around the stitching.
However, the more taping a jacket has, the less breathable it will be. As previously mentioned, traditional GORE-TEX is a versatile fabric that can be used for all kinds of activities, from mountaineering to everyday wear. With these kinds of activities you want a jacket that breathes well, allows for plenty of movement and provides plenty of protection.
Whatever jacket you choose, you should also consider how using base layers for ultimate protection against perspiration. Maybe you are wondering where its name originates from, or what are the characteristics that make it so famous and so widely used, for the most different purposes. In fact, in Robert W.
Gore, son of Wilbert L. It was patented in and for the invention of the innovative fabric, Robert Gore was included in in the U. National Inventors Hall of Fame. Sources: wikipedia. The ePTFE gives the fabric these characteristics. It therefore consists of about 9 billion micro pores per square inch about 1. These are small enough to not allow water to enter from the outside, but large enough to allow sweat to escape.
A Gore-Tex fabric for outdoor clothing, is made up of several layers. For example, it can be composed of these layers see image below : An inner layer of soft lining on which is placed a layer of protection, and above this is placed the Gore-Tex membrane. This conformation allows sweat to escape, not allowing water and wind to pass through the fabric and membrane.
Outerwear materials are a multi-billion dollar industry with Gore-Tex currently standing as the most high-profile brand in the market. But Gore-Tex is not without its challengers.
Other brands have utilised treated polymers to produce other membranes with similar effects to Gore-Tex, including:. Tokyo-based brand Nanamica is known for its lightweight jackets that utilize technical fabrics and construction methods. This stealthy shell is constructed from 3-Layer Gore-Tex black nylon and features a double zip-and-snap closure for extra water resistance.
As well as a packable hood and adjustable cuffs, this Gore-Tex jacket also comes with dual flap pockets, a zipped chest pocket, and interior storage compartments. Seen here in full-grain brown leather, this boot is made in the U. Japanese bag-masters Porter have produced this seemingly indestructible backpack using Gore-Tex technologies and durable fabrics.
The outer textile is super tough denier Cordura nylon which has been coated with four layers of water-resistant urethane. Coming in a 36 Liter capacity, this tank of a backpack has a plethora of pockets and compartments for your daily carry, as well as a wealth of buckles and straps to keep the bag secure.
