The diversity and characteristics of hiking required the application of a range of solutions that will work in changing terrain and climatic conditions. The combination of advanced technologies increases effectiveness in protection against cold and moisture at every stage of the expedition.Thanks to wind-resistant fabrics and membranes protecting against moisture, the trekking jacket will be suitable for both long-distance hikes or one-day hiking or backpacking. Lightweight construction makes it wearable in warmer days. It has a regular fit, which comfortably adapts to the silhouette and a standard length reaching the hip line. The jacket can be used alone as a waterproof outer hardshell layer or in combination with clothing serving an insulating function, e.g., with a thin down jacket or thermal underwear.
