ACTIVE MOISTURE MANAGEMENT

  Moisture produced by the body in the form of sweat must be transported effective...

  Moisture produced by the body in the form of sweat must be transported effectively away from the body before it can condense on the skin and cause undercooling. We have developed various fabrics with active moisture management (“wicking”) capabilities.

  They consist predominantly of polyester or polyamide based yarns with Q.M.C. (= Quick Moisture Control) attributes. The special fibre structures wick moisture rapidly away from the body to the outside surface of the fabric, where it can evaporate effectively.

  You will find fabrics with active moisture management in our functional underwear and base layer ranges and in many of our outdoor pants and shirts.

ANTIMICROBIAL CHARACTERISTICS

  Fabrics with an antimicrobial effect inhibit the growth of odour causing bacteria. The effect is limited to the fabric itself and does not apply to bacteria on the skin. 
  Some fabrics have micro silver particles embedded in the fibres, while others such as TENCEL (made from Lyocell fibres) have intrinsic antimicrobial properties. Both reduce the formation of odour causing bacteria in a natural way. Fabrics with silver particles are used in our functional underwear, while TENCEL fabrics are used in our functional outdoor shirts.

  Unfortunately, static charges have various causes, some of which it is not possible to do anything about. On a soft shell fabric, fibres can often stick more firmly than can be the case with harder, smooth materials.

  If you have problems with fluff on your jacket or clothing, we recommend that you treat it with an anti-static spray in order to reduce the charge and therefore the adhesion, and regularly remove fluff with an adhesive roller.

  The Layering System consists of three inter-compatible and mutually complementary clothing layers, each fulfilling a concrete function:
  
  The First Layer is the layer that comes into direct contact with the skin. Also known as the "base layer", as a rule it is required to deliver only limited thermal performance but it must be capable of moving sweat effectively away from the body to prevent chilling.
  
  In winter, a degree of heat retentivity is also desirable. Our ultra-functional DRYBASE THERMIC and DRYBASE SUPERTHERMIC underwear was developed specifically for this purpose.

  The Second Layer provides the insulation and must be capable of readily transporting the moisture expelled by the first layer to the next layer in the system.
  
  We have included various different weights of fleece and super-lightweight interlined garments in our winter collection, to enable you to select the best-fit blend of insulation, low weight and pack size to suit the temperature and the activity you have in mind.

  The Third Layer delivers the weather protection. It must be waterproof and windproof.
  
  High breathability is also desirable, to enable the moisture expelled through the inner layers in the system to escape to the outside atmosphere. Our TEXAPORE weatherproof jackets fulfil these criteria perfectly.

  Products to refresh the mosquito protection are not included in our range. The reason for this is that with private use of such products we have no influence over the amount used and the method of application and are therefore unable to guarantee the outcome. 

  For our functional fabrics with insect and mosquito protection we use VITAL PROTECTION technology by HealthGuard HealthCare Ltd. (HHL technology). This provides effective protection from insect and mosquito bites.  

  HHL anti-insect technology is rooted in the fabric itself. We check the dosage and the method of application to ensure that the treatment is perfectly safe for both the wearer and the environment. HHL technology complies fully with the Eco-Tex 100 Standard. It has been tested by independent, accredited toxicological and dermatological institutes and found to pose no risk to human health.

  Jack Wolfskin opted to renounce the use of products with nanotechnology with effect from the 2010 Winter Collection. The decision was in response to ongoing public debate over the long-term effects of such products, which has still to be properly researched, and followed the updating of a 2009 study by the German Federal Environment Agency, Nanotechnology for Humans and the Environment. The study primarily illustrated the opportunities resulting from nanotechnology, but also touched on the possible risks. The use of nanotechnology on textiles is, in comparison to other areas of use such as in cosmetics or food, generally considered not to pose a risk to humans. According to the study, there may be greater risks for the environment, as the nanoparticles found on the fibres could possibly separate and be released into the environment after washing.

  Up to Winter 2010, Jack Wolfskin made use of nanotechnology by the manufacturer NANO-TEX. Tests conducted by the Hohenstein Test Institute have determined that there are no nanoparticles applied to the surface of the fibres in the NANO-TEX technology used by Jack Wolfskin.  The technology is based on a molecular alteration of the fibre structure, which results in improved water and dirt-repellent properties. The nanoparticles are not expected to separate, aside from the normal abrasion found with all fibres. This would seem to indicate that the technology poses no risk to humans or to the environment. Nonetheless, Jack Wolfskin has decided to refrain from the further use of nanotechnology for now, until further research results become available.

  A variety of tests were carried out by the manufacturer when developing the NANO-TEX finish in 2005. These focused in particular on skin tolerance and certain chemicals that clothing should not contain.

  The results were positive, so we decided to use the finish for our products. The issue of the release of nano-sized particles, which is now being discussed, has not yet been examined. From where we currently stand, it is therefore not possible to certify that NANO-TEX products are harmless. However, the description of the technology would lead us to believe that NANO-TEX is most likely harmless.

  The report by the UBA points out that the risks posed by nanotechnology have not yet been researched.Nanoparticles in cosmetics and foodstuffs appear to be particularly problematic. In the field of clothing, studies in the USA and Sweden have shown that nanoparticles of silver can come loose when the clothing is washed and can get into the waste water.

  
  The UBA itself tested the abrasion characteristics of textiles with nanoparticles of titanium dioxide and noted that no nanoparticles were released.However, neither of these investigations involved the NANO-TEX technology that we use. There are therefore general references to risks caused by clothing with nanotechnology, but none regarding the fluorocarbon technology in NANO-TEX.

  On November 13th Jack Wolfksin received an updated statement from the American manufacturer of the Nano-Tex finish regarding the discussion of nanotechnology. The original document is available as a download version:

  "Nano-Tex is aware of a study on the toxic effects of nanoparticles. We are also aware of additional scientific investigations into the means and effect of nanoparticle transfer and absorption.

  These studies and their findings bear no relevance to the family of Nano-Tex products (Nano-Tex, Nano-Care, Nano-Pel, Nano-Dry, Nano-Touch). The polymers used in Nano-Tex treatments durably bind to the fabric’s fibers through a patented attachment technology. Additionally, Nano-Tex treatments are designed to be non-bioabsorbant; the polymers used are too large to be absorbed into the skin or inhaled. Furthermore, Nano-Tex does NOT use nanotubes, buckyballs or any other nanomaterials that could be ingested or inhaled.

  All Nano-Tex products comply with all known environmental and health and safety standards, worldwide."

  "Jack Wolfskin will voluntarily be renouncing the use of Nano-Tex products as of the coming 2010 winter collection. This is based on the ongoing public debate over unresearched long-term effects, which was brought into the open at the end of last year when the German Federal Environment Agency updated the 'Nanotechnology for humans and the environment' study.

  The study primarily illustrated the opportunities resulting from nanotechnology, but also touched on the possible risks.The use of nanotechnology on textiles is, in comparison to other areas of use such as in cosmetics or food, generally considered not to pose a risk to humans. According to the study, there may be larger risks for the environment, as the nanoparticles found on the fibres could possibly separate and be released into the environment after sufficient washing.

  Nanoparticles in the technology from the manufacturer Nano-Tex used by Jack Wolfskin are not expected to separate, aside from the normal attrition found with every common fibre.The technology is based on a molecular alteration of the fibre structure, which results in improved water and dirt-repellent properties.

  There are no nanoparticles applied to the surface of the fibres in the technology used by Jack Wolfskin.This is ensured by tests commissioned by Jack Wolfskin in the Hohenstein test institute. Consequently, no risk is expected for humans or the environment.

  Nonetheless, Jack Wolfskin has decided to refrain from the further use of nanotechnology for now, until further research has been performed.

  The Nano-Tex products from the Summer 2010 collection already manufactured at the time of the study’s publication are available from the Jack Wolfskin online shop, along with the accompanying product descriptions and further information from Nano-Tex. Furthermore they can be purchased among the known retail channels.

  The softshell concept has its origins in mountain sports. Climbing and mountaineering are strenuous, sweat-inducing activities that also require best possible freedom of movement. And when it comes to weather protection, windproofing and insulation are frequently more important than waterproofness.

  There is no clear definition of a softshell in the outdoor branch. For this reason, there are many different jackets that are designated as softshells. Jack Wolfskin softshells are characterised by the following key attributes:

  - they provide adequate protection in 90% of weather situations and are (extremely) wind resistant and water repellent; some are even totally windproof. In heavy, persistent rain the softshell is usually replaced by or supplemented with a weatherproof ‘hardshell’ jacket.

  - they are made from kinetic stretch fabrics and thus deliver good freedom of movement.

  - as a rule, the breathability rating is higher than our TEXAPORE weatherproof jackets (hardshells), which means that softshells offer the best wear comfort for practically every outdoor activity.

  Softshells do not claim to provide maximum protection; rather, they offer the optimum mix of weather protection and wear comfort. The softshell motto is: “Put it on and leave it on!”

  Print

  We offer two basic types of softshells. These are based on the two ‘fabric families’ used, which are selected in accordance with their potential area of application:

  STORMLOCK: With this family of fabrics, the main focus is on weather protection. STORMLOCK softshells are always windproof and extremely water repellent. They are also breathable and have kinetic stretch properties.

  FLEX SHIELD: The main advantages of FLEX SHIELD fabrics are their excellent climate comfort and outstanding breathability. They are also wind resistant and water repellent.

  Within each of the two fabric families there are different versions of fabrics, e.g. very light or very robust, but all have the typical STORMLOCK or FLEX SHIELD attributes.

  TEXAPORE fabrics consist of a shell fabric firmly bonded to a weather protective layer (a coating, a membrane or a coating/membrane hybrid).

  With all TEXAPORE fabrics, for effective moisture vapour transmission to occur an internal/ external temperature/pressure differential must exist.

  As a rule, the coatings are microporous. The pores of the coating are large enough to allow moisture vapour molecules to pass through but too small to allow the passage of raindrops.

  The membranes are frequently pore-free. In this case, the moisture vapour transmission functions in a physical/chemical way and is based on molecular movement. There are also macroporous membranes, which are additionally air-permeable. This allows a constant process of air exchange (convection) to occur through the membrane, which supports and enhances the moisture vapour transmission.

  TEXAPORE is our in-house (i.e. developed by Jack Wolfskin) weather protection technology. All TEXAPORE fabrics are waterproof, breathable and windproof. Most of them are 2-layer fabrics (abbr. “2L”), i.e. an outer (shell) fabric firmly bonded to a weather protective layer  (a coating, a membrane or a coating/membrane hybrid). In the 3-layer laminates, the lining is also bonded to the outer fabric and the TEXAPORE layer.

  There are many possible combinations of coating/membrane/hybrid and shell fabric, which means there is a wide choice of weather protection materials available. The choice of shell fabric with which the weather protection layer is bonded determines factors such as texture, tearstrength, abrasion resistance and to a large extent the overall weight of the material.

  In order to develop weather protective apparel suitable for a wide range of different applications, there are several versions of TEXAPORE with different performance levels available to us, which differ in terms of breathability and waterproofness, and in their constructions. You can learn more about these performance levels here.

  There are now a total of more than 40 TEXAPORE fabrics. However, not all of them appear every season in our collection. The TEXAORE versions are differentiated by their key attributes (texture, robustness, kinetic stretch properties, etc.) and their technical specifications or performance levels.

  As a rule, the names of the TEXAPORE fabrics consist of three component parts. The first part refers to the performance level (more info here), e.g. TEXAPORE 4x4. The second component describes the outer (shell) fabric, e.g. OXFORD, and often provides an indication of the characteristics of the weather protective fabric. The final part indicates how many layers the fabric is composed of, e.g. “2L” stands for a two-layer laminate.

UV PROTECTION

• Are products with a SUPPLEX® UV filter also suitable for people with sun-cream allergies?

  As a general rule with JACK WOLFSKIN products, UV protection is always provided ...

  As a general rule with JACK WOLFSKIN products, UV protection is always provided via the twine and the structure in materials for clothing. This long-lasting function does not wash out, nor does it work by means of chemical filters.

  Measurements according to standard AS/NZ 4399-1996 and ITS certification show that the material made from SUPPLEX® fibres for these items has a UV protection factor (UPF) of 40+, even in the lightest colour combination.

  UV protection is important. However, conventional lightweight fabrics used for normal summer clothing allow more UV light to pass through than one might think. Effective UV protection is therefore a central theme of our TRAVEL apparel line. In order to reduce the use of chemical skin protection agents to the minimum required, we have developed a range of TRAVEL apparel with high levels of intrinsic UV protection.

  The advantages are obvious:

  • The function is intrinsic to the fabric itself and is not dependent on any additional treatment.
  • The protection is long lasting and does not diminish through sweating or contact with water.
  • The UV protection factor is significantly higher, which means the clothing is suitable for wear in extreme sunlight.

  Jack Wolfskin has determined that SUPPLEX is the ideal fabric for the purposes of UV protection. This specialised nylon yarn is worked into various fabrics, all of which have a high UV protection factor (UPF) of 40. The number 40 denotes that a maximum of 1/40 of harmful UV rays will penetrate the fabric. In other words 97.5 % of the rays are filtered out.

  In addition to UV protection, SUPPLEX has the following characteristics:

  • It has a smooth, skin-friendly feel.
  • It is easy-care, crease resistant and dries very rapidly.
  • It is very light yet robust and retains its shape well.

  Print

• How does UV protection work with regard to clothing?

  For our UV protective clothing we only use fabrics where the UV protection is not achieved by means of a chemical treatment. Instead, the protective function results from the use of special yarns and/ or fabric constructions (e.g. extremely dense weaves).

   

  The advantages:

  • The function is intrinsic to the fabric itself. 

  • The protection is long-lasting and is not diminished by perspiration or contact with water. 

  • The UV protection factor is also suitable for strong sunlight.

   

  Clothing with a UV protection factor of 30 or more is specified by us as such, in accordance with the Australian/New Zealand AS/NZS 4399:1996 standard.

  As an example, if an article of clothing has a specified UVP of 40, this denotes that a maximum of 1/40 of harmful UV rays will penetrate the fabric. In other words 97.5 % of the rays are filtered out.

  Yes.  This is because the UV protection is not achieved through the use of chemical filters, cosmetic agents or special fabric treatments but by the use of special yarns or fabric constructions. This also has an additional advantage: the protective effect is long-lasting and will not wash out.

  The UV protection factor of our apparel is defined in accordance with the Australian/New Zealand AS/NZS 4399:1996 standard und ITS certificated. Clothing with a UV protection factor of 30 or more is specified as such in accordance with the above standard.

  As a general principle, we recommend the use of sun screen on uncovered skin (at least), to ensure comprehensive UV protection.

  Moisture vapour transmission (breathability) is an important attribute for waterproof clothing.

  The moisture vapour transmission is denoted by the so-called “Moisture Vapour Transmission Rate”, or MVTR for short, and is given in g/m²/24h.  The figure indicates how much moisture vapour a square metre of fabric will allow to pass through in a 24 hour period (g/m²/24).

  The greater the MVTR, the better the moisture vapour transmission (and thus the breathability) of the fabric.

WATERPROOFNESS / WATER COLUMN

• What is waterproofness / water column?

  In the textile industry, the waterproofness of materials is normally specified i...

  The water column or hydrostatic head ratings denote the level of water pressure that a fabric can withstand before water penetration occurs. The waterproof specification of a fabric is generally stated in water column/ hydrostatic head millimetres.

  The higher the hydrostatic head rating of a fabric, the greater the water pressure it will withstand, i.e. the greater the waterproofness. Our different versions of TEXAPORE have different performance levels and achieve hydrostatic head ratings from 1,700 to 50,000 mm. To give you an example: when sitting on wet grass in a pair of waterproof pants, the pressure on the fabric corresponds to a hydrostatic head of approx. 2,000 mm. 

  Nowadays, pressure is almost always measured in millibar (mbar) or Pascal (PA). However, in the textile industry, the terms “water column” and “hydrostatic head” have become commonplace, with water pressure data given in millimetres (mm). This convention originates from the time before analogue or digital pressure measurement gauges were available, when the pressure exerted was read off from the level of a column of water in a standard measuring vessel. 

  Example: a reading of 600mbar on a modern pressure gauge can be converted to give a water column (hydrostatic head) value of 6,000mm.

  By way of illustration, a 6m (6,000mm) high water column acting on a norm surface of 100cm² weighs 60kg and exerts a pressure of 60kPa (600mbar)

ZIP SYSTEM

• What are the differences between the various zip systems used by Jack Wolfskin?

  Jack Wolfskin offers three different ZIP SYSTEMS:

  There are three different system zips:

   REGULAR SYSTEM ZIP
  The system zip for normal and longer style jackets, found predominantly in our HIKING and TREKKING lines.

   
  SHORT SYSTEM ZIP
  A shorter system zip, used in the sporty, cropped length jackets in our ALPINISM and HIKING lines.

  
  KIDS SYSTEM ZIIP
  The system zip found in our FAMILY line for children and youngsters. The zip works in the same way as the system zips in our adults’ range of jackets.

   

  Our weatherproof shell jackets with system zips actually have two zips: the main front zip and the system zip itself. The inner jackets have only one, the system zip.The shell jacket and inner jacket can be docked by means of the system zip and the docking loops located at the collar and cuffs.

  For mutual compatibility, the system zips on each jacket must be of the same length. In other words, weatherproof shells and fleece jackets equipped with the REGULAR SYSTEM ZIP can be combined, as can those equipped with a SHORT SYSTEM ZIP.

  The product description will indicate whether a particular jacket has a system zip and if so which type it is equipped with.

• Why do women's jackets have zippers that fasten on the left and men's jackets have zippers that fasten on the right?

  In days when it was the custom for gentlemen to wear a sword, the weapon was generally carried on the left, since this made it easier to draw (most men are right handed). To prevent entanglement in the jacket, dress coat or cape, the garment had to fasten from left to right.

  When a gentlemen was out with a lady he would always walk, or sit, on her left to avoid interference with his weapon. Since it would be highly inappropriate for a gentleman to get even the briefest glimpse of a lady?s underwear, a sight that was reserved solely for her husband, her upper garments had to fasten from right to left.

  This is the origin of the custom that men's zips fasten on the right and women's zips fasten on the left and why the zip flaps are open on different sides.
