What is Gore-Tex?
Gore is a fabric manufacturer best known for their waterproof, breathable fabric Gore-Tex. The key to Gore-Tex is a membrane which provides the tech performance of the fabric; it is made of the same Teflon that is used to make your pots and pans non-stick. The real trick is making this super non-stick and delicate substance stick the the protective fabrics which turn it into the outdoor fabric we know and love. The bit which makes Gore-Tex special is this glueing process which is done in their top secret, big, blue machine. Only a few members of Gore’s staff know how this is done, it’s one of the biggest secrets in outdoor kit and has been the subject of many a nerdy forum post.
3-Layer Gore-Tex Pro
3-layer Gore-Tex Pro Shell is Gore’s top spec fabric and is intended for use in the most extreme of environments, from deep powder skiing to freezing cold Scottish couloirs, this is the fabric that will keep you warm and dry. The 3-layer Pro shell is the thickest and heaviest of Gore’s fabrics but is also the most durable and protective. The ‘3-layer’ part means that the membrane is bonded to both the exterior colourful fabric and an interior ‘scrim’ which is there to protect the membrane and improve its longevity. The breathability is produced by pores in the membrane which are opened by the high pressure inside a sweaty jacket trying to escape to the low pressure of the world outside. This is an ingenious process which means that the fabric can remain waterproof even with these millions of tiny holes; however its performance can be reduced if it is too warm (high pressure) outside the jacket or the fabric is too wet, which blocks the pores.
