HWS – Härkila Weather System

The best membrane for hunting


The HWS® Härkila Weather System will keep you dry on the hunt.

Härkila’s HWS® membrane system is a windproof and waterproof technology, developed specifically for hunting. Our research & development team joined up with some of the World’s leading membrane specialists to create this technology. Together with experienced hunters, we have perfected the technology by testing it in the field.


The result is a range of waterproof, windproof, breathable, and lightweight membranes, tailored to the needs of the hunter. This is a solution for the hunter who wants high performance while staying dry and comfortable, even during high-intensity activity under harsh conditions.

HWS® uses hydrophilic membranes that draw moisture out. The system keeps the hunter dry by rapidly absorbing and removing perspiration. The moisture is wicked through the membrane and distributed over the surface, where it rapidly evaporates and stabilises the temperature inside the garment. At the same time, the holes in the membrane are so small that they prevent water molecules from entering from outside. The HWS® membrane has a high waterproof rating of 20.000 mm and a breathability rating of 20.000 mm.

This is an innovative technology in a robust construction that both enhances adaptability and protects the hunter from the elements.
