Membranes are a wafer-thin separating layer that provides waterproof protection. The microporous membrane blocks the path from the outside to the inside with billions of microscopically small openings of moisture, since a drop of water is 20,000 times larger than the membrane openings. Since sweat in form of water vapor is much smaller than these openings, it can penetrate the pores unhindered. There are also hydrophilic membranes that do not have pores, in which the water density is achieved by a closed surface. The sweat is directed to the outside by moisture-absorbing molecules.



Gore-Tex® is a wafer-thin membrane and can be used in jackets, trousers, shoes and even socks. The most important advantages of the Gore-Tex® membrane are its waterproof and windproof protection combined with high breathability. The Gore-Tex® GUARANTEED TO KEEP YOU DRY™ Promise can be relied upon even in extreme conditions and when the weather holds unforeseen surprises. Here you will find clothing, mountaineering shoes, hiking & trekking shoes and running shoes. which contain a Gore-Tex® membrane.
Gore-Tex Infinium®

Gore-Tex Infinium® product technologies provide flexibility, style and membrane system functionality in an active everyday life with changing (weather) conditions. They are versatile and for example integrated in water-repellent jackets, slim and fashionable shoes or perfectly fitting gloves. All activities and requirements are supported by Gore-Tex Infinium® with maximum comfort and function.

The elastic and waterproof Toray Dermizax® membrane is hydrophilic, i.e. pore-free, which makes it waterproof and ensures that perspiration is directed outwards through moisture-absorbing molecules. A special thing about Toray is that it uses recyclable polyurethane and not polytetrafluoroethylene like many other manufacturers. Outdoor brands such as Peak Performance, Ortovox, Scott, Crazy Idea, Elevenate, J.Lindeberg and Kjus use this sophisticated membrane technology.

The waterproof and breathable OutDry® membrane is welded directly to the inside of the outer fabric with a patented 3D lamination process. Since there are no seams, the breathability is fully exploited. This efficient technology is often found in shoes but also in jackets and gloves. The membrane is free of fluorocarbon compounds and fully recyclable.

Absolutely windproof. Maximum breathability. Gore Windstopper® products feature an ultra-thin windproof membrane that does not restrict breathability and is also water repellent. Windstopper® products are convincing for hikes, bike tours, running and everyday life. They are often a better alternative to waterproof products as they offer optimum protection in most weather conditions. Here you will find products from the areas of alpine skiing, cross country skiing, snowboarding, biking, ski touring and outdoor that include Gore Windstopper®.

It is a dense fabric that is highly water-repellent thanks to its capillary effect and at the same time highly breathable. The weave makes Pertex® particularly robust and durable. The material is often used as an outer cover for insulation material, it can be found in jackets and sleeping bags and is available in various versions.



Down Down is known everywhere for its excellent thermal performance. But what makes it so special? Down nestles under the feathers of waterfowl. Unlike feathers, down has a core of which several soft, intergrown hairs are lost like snowflakes. Here small gaps are formed, which make it possible to store the heat. There is almost no other material with such a good heat property. There are differences in the quality of down. Goose down feathers are of higher quality than duck down feathers and the mixing ratio is also important. The rule of thumb here is “the greater the proportion of down, the higher the quality of the product”. When it comes to insulation, it’s about the so-called bulking power or fill power. This means that with a larger filling volume the insulation value is better, i.e. warmer. You can find down in jackets, vests and sleeping bags.

PrimaLoft® is a synthetic fiber insulation made of polyester which is known for its high thermal performance at low weight and small packing size. Its thermal properties are similar to those of down, but Primaloft® insulation also warms in wet conditions and does not apply. PrimaLoft® offers the right insulation for a wide range of activities. All PrimaLoft® products meet the Oeko-Tex Standard 100 % and 90 % also the bluesign® Standard. In their two product lines, Gold and Black, PrimaLoft® values ​​environmental friendliness and uses recycled materials such as fibers from used plastic bottles. Here you can find clothing, ski boots and outdoor shoes with PrimaLoft® synthetic fiber insulation.
Fleece Cosy warmth for all outdoor activities. Fleece is a breathable insulation layer that is ideal as a second layer. The classic fleece is made of polyester and is very absorbent thanks to the soft and roughened inside, so the body stays dry and warmed at the same time. Meanwhile, there are many variants that use different material combinations, strengths and processing methods to make the material warmer, lighter, more elastic or more robust. You can find fleece in clothing, boots and even backpacks and bags.
Merino Merino wool comes from merino sheep, one of the oldest and most resistant sheep breeds in the world. They can withstand extreme temperature differences due to their origin and coat characteristics. Merino wool has odour-repellent properties and UV protection. It balances temperature, regulates humidity and warms depending on the thickness of the wool. In addition, merino wool is a natural and renewable raw material and biodegradable.You can find them in jackets, vests, pullovers & shirts, pants, dresses & skirts, baselayers, gloves, socks or caps.
Swisswool &  Tirolwool

The wool fibre from Switzerland or Tyrol is characterised by excellent thermal properties and excellent climate comfort as well as by its regional origin. The wool is temperature-regulating, as the wool fibres are strongly crimped, offering plenty of space for air in between. This air serves as an insulating layer, summer and winter, against heat and cold. The wool fibres can absorb up to 35% of their own weight in moisture without feeling wet. The regionality distinguishes both Swisswool and Tirolwool, they support the local sheep farmers and ensure, for example, a fair wool price. Here you can find products that contain Swisswool.



Cotton Cotton is a natural fibre obtained from the fruit capsules of the cotton plant. Products made of cotton are soft and comfortable to wear, hard-wearing, breathable and easy-care. Cotton stores moisture and, like functional fibres, does not transport it further. Cotton has been processed into fabrics and clothing for at least 5000 years.
Organic Cotton In contrast to conventional cotton cultivation, the use of chemical pesticides and fertilizers in organic cotton is prohibited. With organic cotton, the amount of water required for cultivation is reduced because the farmers plant the plants on a thicker layer of humus. In addition, genetically modified cotton plants consume more water than naturally planted ones.
Polyester Polyester is a synthetic material that is used in many ways today in the manufacture of clothing. Synthetic fibres made of polyester are produced in the so-called melt spinning process. First, polyethylene terephthalate, better known as PET, is produced. The basis is crude oil. Heat creates a melt that is pressed through spinnerets and transformed into fibers. Polyester is extremely easy-care, dimensionally stable, hardly absorbs water and is very light.
Recycled Polyester Products made of recycled polyester consist of recycled PET plastic bottles, old goods or waste cuttings. The use of materials that are already in circulation reduces the use of new raw materials, especially those from non-renewable sources. This has tangible consequences: a reduction in air, water and soil pollution. The processing of recycled polyester also reduces dependence on oil. The recycling of used polyester clothing is also encouraged. For example, five soda bottles provide enough yarn for an extra-large T-shirt.
Lyocell Tencel Lyocell, also known as Tencel, is an industrially produced fiber made from natural raw materials. It is made of wood and is biodegradable. The soft fiber offers pleasant warmth and breathability and regulates moisture transport in a natural way. Lyocell is also extremely tear-resistant when wet and therefore a very durable material. The special thing about the production of Lyocell is that the manufacturing process is hardly environmentally damaging due to the use of environmentally friendly solvents and a closed material cycle. Lyocell is the generic fiber name offered by Lenzing AG under the brand name Tencel.
Modal Modal is made of beech wood and is a pure cellulose fibre. The raw material is debarked, separated into small chips and processed. Finally, a honey-like mass is produced which is pressed through microfine nozzles and the fibres are spun. These processes can be carried out purely industrially, which is why Modal, despite its natural origin, is classified as a chemical and synthetic fibre. The Modal fibres can only be spun particularly thinly and thus convince with their soft wearing comfort, elasticity and dimensional stability. Their fast moisture transport makes them particularly popular in the outdoor industry.
G-1000® The durable and breathable G-1000® material is used by Fjällräven for all products – backpacks, jackets and pants. It is a densely woven fabric of 65% polyester and 35% cotton that can be adapted to different weather conditions with Fjällräven’s Greenland Wax. The material is durable and supports you in all your adventures.
Vibram® Soles

Already in 1937 the Italian Vitale Bramani applied for a patent for the first soles. The special feature of the Vibram® soles is the rubber compound which is adapted to the respective field of application. Its grip and abrasion resistance make it popular for all sports, it is used for mountaineering boots and winter boots as well as work and climbing shoes. In addition to the rubber compound, the tread of the shoe sole also provides support and safety.
Perwanger® Leather

The Perwanger company, which has specialised in leather since 1780, is still a family business today and produces exclusively technical, water-repellent and breathable leathers. Due to the excellent properties of the product, the leathers are used in various areas of high-quality, technical shoe manufacturing. The raw material comes from cattles from Northern Europe, which is produced during meat production and is further processed in Italy. Here you can find shoes made of Perwanger® Leather.




The bluesign® system is the solution for the sustainable production of textiles. It excludes environmentally harmful substances from the manufacturing process right from the start, lays down guidelines and monitors compliance with them for environmentally friendly and safe production. On the one hand, this ensures that the finished textile product meets the strictest consumer protection requirements worldwide. On the other hand, it gives consumers the confidence to buy a sustainably manufactured product. Products that have been processed at least 90 percent in certified factories may bear the bluesign® seal. bluesign technologies AG in St. Gallen, Switzerland, was founded in 2000 by textile and chemical experts and developed the holistic bluesign® system based on the principle of Input Stream Management. Partners of bluesign® are Haglöfs, Houdini, La Sportiva, Maloja, Norrona, Patagonia, Schöffel, Vaude, Deuter, Edelrid, Salomon, Marmot and Salewa.

Fair Wear Foundation

The Fair Wear Foundation (FWF) is a non-profit organisation which, together with its member companies and other partners such as trade unions, NGOs, factories, business associations and governments, pursues a clear objective: the improvement of working conditions in the garment industry. In order to create long-term solutions, the FWF works at various levels: It regularly reviews, evaluates and reports publicly on the progress made by its member companies. These include on-site inspections at the production sites and interviews with workers. On the other hand, the FWF also reviews the business practices of the companies and their influence on the working conditions at the production sites. Fair Wear certified brands include Deuter, Haglöfs, Odlo, Ortovox, Schöffel, Dynafit, Salewa, Mountain Equipment, Mammut and Vaude.
Sport Conrad Recycling

Sustainability is an issue that concerns us all. Recycling is also playing an increasingly important role in the production of clothing. To keep the overview, Sport Conrad labels clothing that is made of recycled material or that is recyclable with the Sport Conrad Recycling logo. Many outdoor manufacturers produce clothing from fully recycled or partially recycled materials. Such as recycled down, old bed linen or clothing. Recycled nylon, polyester from recycled plastic bottles or recycled wool is also used. Some manufacturers even offer to reprocess and recycle their customers’ old clothing.

Sport Conrad also wants to take responsibility in the area of environmental protection and never lose sight of the impact our products have on the environment.
In order to provide a better overview, we have developed our own label that identifies particularly sustainable and environmentally friendly products – the WIR DENKEN UM label.
