  • Combining different face fabrics with complementary characteristics in order to optimize the garments properties.

    Why do we use UF PRO® Hybrid/Design?

    Usually garments are made of one certain type of face material, which defines the textile characteristics of the garment. To our mind this does not satisfy the performance requirements, as it usually offers just a compromise. Often the technical performance of just one material does not thoroughly fulfil all the complex functional and physiological requirements, of the human body in motion.

    Therefore we have switched from the single outer fabric design to a more sophisticated technology that we call Hybrid/Design. This design technology uses the material properties of different and complementary materials in different areas of the garment, as it is required by the expected end use during which it is worn.


    How does Hybrid/Design work?

    The basic principle for UF PRO® Hybrid/Design is that the functional and physiological requirements of the expected end use, define also the characteristics of the materials of choice.

    In areas for example, where elasticity is required, we use stretch materials usually coming from the Swiss premium manufacturer Schoeller®. In areas which require a rather solid platform for pockets and protectors, we choose solid materials without stretch. In areas, which require the best possible breathability, we use light and highly air permeable materials. Wherever durability is paramount we use highly abrasion resistant fabrics.

  • A technology which provides better mobility in thermal insulation trousers.

    We use Flex/Zone in our UF PRO® garments, wherever we cannot use stretch materials in order to provide the elasticity, which is required during motion. This is especially important in insulation garments, where built in stretch materials would immediately lead to a loss of insulation properties.


    Why did we develop the UF PRO® Flex/Zone?

    While field testing thermal insulation garments we experienced an issue that seems to be typical for all extreme cold weather garments. They are either bulky, or limit your mobility, or they are not warm enough. This turned out to be a real serious challenge in thermal insulation trousers. Therefore we developed a new technology, which is the UF PRO® Flex/Zone.


    What are the benefits of the UF PRO® Flex/Zone technology?

    For the first time we can make thermal insulation trousers tight fitting, without compromising mobility or thermal insulation. This makes movements in cold temperature regions much easier and comfortable, and one can significantly reduce the noise development, which is usually created by material rubbing against each other.

  • Total protection against wind with maximum breathability.

    What is WINDSTOPPER®?

    The WINDSTOPPER® material combines total protection against wind with maximum breathability. This helps to keep the wearer warmer in any windy conditions and more comfortable with fewer layers and less bulk. Most of our UF PRO® windproof garments are made out of the original W.L. Gore WINDSTOPPER® soft shell materials, which provide superb breathability and wind protection. They keep you comfortable and protected against the wind chill effect across a wide range of weather conditions and activities. You can focus on your job without the distraction of being cold, damp or overheated.

    How does it work?

    In this three layer construction, the WINDSTOPPER® membrane is bonded to a high-performance, abrasion-resistant and water-repellent face fabric on one side, and micro fleece with high-performance insulating properties on the other.

    How is it tested?

    The high performance of WINDSTOPPER® products results from the systematic application of the "fit for use" principle. Each time a product is developed, the end product is analyzed. Therefore we are sure that all our UF PRO® garments with WINDSTOPPER® soft shell material perform like expected, even under tough conditions.

  • Lined with Hi-Tech thermal insulation for extreme cold conditions.

Thanks to the new UF PRO® Flex/Zone construction, the Delta OL 2.0 are one of the first thermal insulation trousers that are tight fitting, and at the same time offering excellent thermal insulation and mobility.

Long side zippers make them easy to be put on, even without taking off your boots. Front pockets with a thin fleece insulation lining, a windproof and water-repellent outer material, detachable suspenders and other very useful functional elements ensure a great wear comfort, even in very low temperatures.
