Dermizax – a different kind of membrane
Picture this: You’ve been lugging around a heavy pack for hours in the pouring rain, trying to make the most of the bad weather. And to your surprise, you notice that underneath your waterproof jacket it doesn’t feel like a sauna, even though you’ve been sweating like mad. How’s that even possible? Well, the jacket seems to be doing its job: protect you from the rain and wick moisture away – no matter the weather!
Dermizax was developed in Japan by the company Toray. Compared with other membranes such as Gore-Tex and eVent, this membrane boasts incredibly clever characteristics that really shine in functional outdoor clothing.
In contrast to several other membranes, the polyurethane Dermizax membrane is absent of pores, so there is nothing that could get clogged up. The fabric is “hydrophilic, which – simply put – means that there are tiny molecules with a strong affinity to water in the membrane that transport moisture to the outside. These hydrophilic molecules move more quickly through the membrane at higher temperatures, regardless of whether its the surrounding temperature or your body temperature that is high. So, if the humidity and warmth increases on the jacket’s interior, the difference between the inside and the outside temperature causes the molecules to transport more moisture to the outside.
Like all membranes – regardless of whether they have pores – if it weren’t for the difference in temperature, there wouldn’t be any breathability.
The nonporous construction serves to provide more breathability as the intensity of your movements increases and allows for more moisture and heat to be transferred to the outside. When you take breaks or are out on cold days when you don’t sweat as much, the membrane will keep you from getting cold because heat can’t escape through the pores. Thus, with a Dermizax membrane, you’re getting a membrane that is very variable in terms of its breathability. Another advantage of nonporous membranes is the fact that there aren’t any pores that can get clogged. The pores on conventional membranes are usually clogged by dirt or salts. The salts accumulate on the membrane as a result of our sweat and end up reducing its breathability.
Caring for the membrane is really easy as well. It doesn’t require any special detergent. Plus, you can wash Dermizax clothing as much as you want without diminishing its functionality in any way.
Another advantage of clothing with a Dermizax membrane is how it feels. The fabric is stretchable in all directions. So, not only is the fabric comfortable and robust, but it will also give you the mobility you need for outdoor activities. In fact, the membrane can stretch up to 200% in all directions without you having to worry about it getting damaged.
Thanks to the very thin and soft membrane, garments with a Dermizax membrane feel great against the skin – a tangible plus in terms of comfort.
Dermizax is now being used by a wide array of outdoor clothing brands. The very well-known Scandinavian outdoor company Bergans of Norway loves Dermizax! The Scandinavians place much more emphasis on the functionality and reliability of membrane than marketing. Plus, you can be sure that whatever material is capable of withstanding the harsh conditions of Norway will be perfectly suited to meet the requirements of your outdoor adventures.
