Climate Comfort

Climate comfort is closely connected to weather protection. There was a time when you still used to end up wet in waterproof clothing – not from the rain, but from your own sweat. Continually-improving weather protection fabrics and intelligent design and detailing have made this a thing of the past. Jack Wolfskin have done much more than just develop new breathable waterproof fabrics. Their researchers test unique fabric combinations and develop innovative ventilation systems. If a principle works well in one area, they automatically look to see where else it can be applied.


Climate comfort matters most at the area where sweat is produced, i.e. directly next to the body. When you are out and about, of course, that feeling of well-being is the result of a number of contributory factors and applies to all of your gear. This is why they also invest so much time and effort in improving the climate comfort across all areas of the collection, including equipment and footwear.


Apparel: When it comes to apparel, climate comfort is inextricably linked with breathability (moisture vapour transmission). As a basic principle, fabrics without a coating or membrane allow more moisture to escape. This is why they spend so much time making their (weather protection) fabrics with coatings or membranes more breathable.


The search for new ideas often leads us to unusual solutions. Who would have thought that industrial filters could have anything to do with weather protection? The ability to see the bigger picture, to think outside the box, often produces important results.


In order for a weather-protection fabric to able to work properly, all the clothing layers underneath it need to do their job first; in other words, to ensure that sweat is quickly transported away from the body to evaporate. Solutions range from specially-structured fibres to intelligent material combinations.


Detailing always plays an important support role; for example, venting pit zips, which allow you to determine the amount of ventilation required, or our Air Flow Collar with its chimney-effect that allows warm air to escape…


Footwear: To what extent is it possible to incorporate climate comfort into footwear? We think that there is plenty of scope. Even when it has to be fully waterproof. It probably comes as no surprise that Jack Wolfskin also use their TEXAPORE weather protection fabrics for their footwear. These breathable, waterproof membranes are ideal. Cross-disciplinary thinking has also yielded interesting results here, too: for example, tried-and-tested details from our equipment department are often incorporated into our footwear.


Above all, though, it’s the construction that really determines the degree of climate comfort. Should a boot have full leather uppers or should it incorporate mesh inserts to allow warm, moist air escape more quickly.


Equipment: When it comes to equipment, climate comfort is generally all about ventilation. Whether rucksacks or tents – the essential factor is that warm moist air needs to escape. Naturally, different solutions are applied to different products. Many Jack Wolfskin tents have classic venting openings. They also use highly breathable inner tent materials that promote good air circulation. With rucksacks, it’s the carry system has that greatest impact on climate comfort. They use perforated foam covered with a mesh fabric and incorporate ventilation channels wherever they can. As a result, Jack Wolfskin rucksacks have a reduced contact surface and well-ventilated back sections.
