A fabric that uses an ultra-thin waterproof coating to provide increased resistance in extreme weather conditions. By combining a densely woven face fabric with a microporous coating, Pertex® Quantum Pro provides a very high level of water resistance while remaining lightweight, soft and breathable.

YKK Vislon® technology involves the use of components made of injected plastic, such as polyacetal, making the zips lighter than metal zips of the same size. They are also characterised by their ease of movement, allowing one-handed adjustment of ventilation.
