Men's detachable technical outdoor pants are made of mechanically resistant, windproof, permanently water-repellent and breathable material AFT Double Weave Pro. The DWR - C0 surface treatment without PFC is more environmentally friendly and ensures non-absorbency of the upper material. The technical cut of the trousers has obliquely designed detachable trousers with side zip fastening. By detaching the trousers, the trousers suddenly become great shorts with a length slightly above the knee. The shorts extend beyond the zipper, which prevents possible scratching of the zipper. The trousers have anatomically shaped knees and a lower edge with width adjustment on a patent that adapts to different shoes and needs. The trousers have an adjustable waist circumference with a belt and have a combination of different types of pockets in the front and back of the trousers. In the front there are two sufficiently deep and comfortable pockets, two zip pockets on the thighs. In the back, the trousers have two deep pockets set lower, which, in addition to their practical function, also have a design function. In addition to the already mentioned technical parameters, the new AFT Double Weave Pro material emphasizes the aspect of sustainable production. The material is also treated with a fluorocarbon-free surface water-repellent treatment, making it more environmentally friendly (PFC free). Bluesign certification guarantees transparency and the use of environmentally friendly resources in production. The pants are ideal for multi-day hiking and demanding movement in the mountains.
