GORETEX©
TREKSTA combines GORE-TEX® membrane with seam sealing process with GORE-SEAM® TAPE. The result is a boot with a guaranteed and durable waterproof protection and maximum breathability. GORE-TEX® membrane is laminated to the boot´s lining fabric to create a high-performance textile. The expanded PTFE portion of the membrane contains over 9 billion microscopic pores per square inch. These pores are approximately 20,000 times smaller than a drop of water, but 700 times bigger than a molecule of moisture vapour. So whilst water droplets cannot penetrate the GORE-TEX® membrane, moisture vapour (a gas) can easily escape.
