An advanced membrane from the Viking brand with high waterproof and windproof performance. It has micropores through which perspiration is evaporated from the body's surface and allows the skin to breathe freely.

HyperLoft™ technology is an extremely lightweight and flexible fabric that provides an excellent barrier against the loss of heat through the skin. At the same time, it does not allow the cold to penetrate. In addition, it absorbs virtually no moisture, making it an ideal choice for long and demanding days in the mountains.
