The DWR coating makes the fabric water repellent, so that water forms droplets on its surface and runs off instead of soaking in. This protects the fabric from getting wet quickly, providing greater comfort in wet conditions, but does not guarantee full water repellency.

An innovative membrane from The North Face which, thanks to its nano-fibre structure, allows air to pass through without sacrificing waterproofness and durability. The nanofibre technology allows the fabric performance to be tailored to the specific sport and use. The membrane has been successfully tested in the harshest mountain conditions.

Aramid fibre material invented by American chemist of Polish origin Stephanie Kwolek, used in the production of, among other things: hiking and climbing clothing. It is characterised by lightness, stiffness, high impact and crack resistance and high temperatures. It is approx. It is about 5 times more impact-resistant than carbon fibre and does not conduct electricity (it is an insulator).
