2. GORE-TEX
Gore-Tex is a waterproof, breathable fabric
membrane. Gore-Tex is able to repel liquid water
while allowing water vapor to pass through, and it
is designed to be a lightweight, waterproof fabric
for all-weather use.
GORE-TEX membrane is the main part of GORE-
TEX fabric and it is high-performance textiles.

4. How does the GORE-TEX membrane
work?
•
The GORE-TEX membrane has 9
billion pores per square inch, with
each pore 20,000 times smaller
than a water droplet. so water
droplet do not pass through the tiny
pore. But these same pores are
large enough for moisture vapor to
pass through, so your body's
perspiration is able to escape.

7. GORE-TEX fabrics offer the
same quality
GORE-TEX fabrics are waterproof,
windproof, and breathable. A truly
windproof fabric air permeability is 1.0
cfm (cubic foot of fabric in one minute)
or less. However, there are many
different outer fabrics you can choose
what's most important to you: weight,
texture, abrasion resistance, and so
on.
