Elvine is known for our stylish jackets with CityFunction©,
by which we mean three things:
Technical functional features such as wind and water protection.
Smart functional details such as magnetic buttons and rain-stopper cap.
Stylish design for a city lifestyle rather than outdoor life.
Our jackets are plenty functional enough for a regular urban lifestyle. In purely technical terms, CityFunction© means that our jackets are treated with a membrane or a coating, vital seams are often taped and the surface is treated with an impregnation free from fluorine compounds.
CityFunction© is not only about weather protection, but also about being comfortable and looking smart in the city. This is evident in the stylish design and in many of the details of our jackets.
A membrane is a thin film that is laminated to the outer fabric and then protected in some way on the inside. Elvine’s jackets either have a 2-layer structure or a 3-layer structure. The 3-layer version is created by bonding together the outer fabric, the membrane and an internal lining. The 2-layer version feels softer and more flexible as the protective lining isn’t bonded to the other layers and is left loose instead. The membranes that we are using are made from Thermoplastic Polyurethane (TPU) or Polyurethane (PU).
A coating is spread onto the downside of the outer layer. The coating is made from various forms of Polyurethane (PU).
You could say that the membrane is like wallpaper but the coating is like paint.
Even with a breathable membrane or coating making your jacket waterproof or water repellent, you may still need to undo your jacket for ventilation when you get hot.
When Elvine uses impregnation, we always use Bionic-Finish® Eco, a water repellent finish free from environmentally harmful fluorinated compounds.
The water droplets run off like beads. Like all impregnation, this surface finish will deteriorate after repeated washes, but can be reactivated by gently adding heat to the jacket with an iron at low temperature and an ironing cloth.
Water column is a measurement used to show the amount of water pressure a garment can cope with before it starts leaking. A garment with a water column of at least 1 500 mm can withstand rain and wind in normal everyday use. If it is exposed to high rain pressure for a long period, you would need a higher water column rating and that’s why many of Elvine’s jackets have a water column of at least 3 000, with some as high as 10 000.
To be called waterproof, all the seams need to be taped as well.
If only vital seams are taped, e.g. the ones in the most vulnerable parts of the garment like shoulders, armholes, neck and hood, the garment can only be called water resistant or water repellent, even if the material itself is fully waterproof.
SELECTED CITY FUNCTION SUPPLIERS
The fluorine free water repellent impregnation
When we use a repellent treatment on our jackets, we always use Bionic-Finish® Eco. Bionic-Finish® Eco from Rudolf Group is a unique, patented water repellent finish for textiles that does not use any harmful perfluorinated compounds.
The innovative technique behind Bionic-Finish® Eco is built on an imitation of the structure of a leaf or the feathers of a bird. The rain drops simply flows off the surface of the jacket like small pearls.
To explain this in chemistry terms, a huge amount of water repellent (hydrophobic) polymers (chemical compounds consisting of very long chains) are formed into a branched star-shaped structure on the textile and crystallise on specifically adjusted comb polymers. So when rain comes in contact with a Bionic-Finish® Eco treated jacket, the water molecules are too big to penetrate the polymer structure.
Keeping buttons in place forever
Button Bind Necklace is a system that secures buttons to clothes. The system secure button necks that need to be of a predetermined length and is built around a self-vulcanizing tape that is wrapped around the threads holding the button to the garment. Elvine uses Button Bind on all of our four-hole buttons.
YKK® make the best zippers in the world
A zipper will never make a garment, but it can break a garment. That is why Elvine use the best fastening products that exist on the market. YKK® make incredibly dependable zippers using the best materials and there is a reason why the saying goes: You can’t go wrong with YKK®.
