The GORE-TEX membrane contains over 1,4 billion microscopic pores per square centimetre. These pores are 20,000 times smaller than a water droplet, but 700 times larger than a water vapour molecule. This makes the GORE-TEX membrane completely waterproof from the outside, while allowing moisture to escape from the inside.
All the different GORE-TEX fabrics are durably waterproof. They must pass an extensive wash/wear test cycle without degradation of their superior properties before being approved for production with the GUARANTEED TO KEEP YOU DRY™ promise.
This makes garments in GORE-TEX fabric extremely long-lasting, and therefore an excellent sustainable choice.
All GORE-TEX garments are fully seam-sealed.
All GORE-TEX garments are fully seam-sealed. The seams are covered with a GORE-TEX tape on the inside of the membrane to make sure that the garments are 100% waterproof. The tape is attached with a special machine using hot air and a hi-tech adhesive. Depending on style, a jacket needs between 12-15 meters of GORE-TEX tape to seal all the seams.
