Most brands name a jacket. Stone Island names the fabric. Open a care label and you get something like Naslan Light Watro Down-TC, which is not marketing language but a description of what the garment is made of and what was done to it. Once you can read those names, two things get easier: you know what you are buying, and you know what it is worth.
Here are the ones you will meet most often.
Nylon Metal
The one people recognise without knowing the name. Nylon Metal is woven from a trilobate nylon yarn, a fibre with a three-lobed cross-section that catches light from different angles. The weave runs a grey weft against a white warp, and the finished garment goes through a double dyeing process at high temperature.
The result shifts colour as you move. A jacket that looks olive indoors reads bronze in sunlight. It is the closest Stone Island gets to a signature fabric, it photographs badly and looks superb in person, and it holds value well on the resale market for exactly that reason.
Naslan
Mechanically spun nylon, tightly woven, light in the hand. Naslan is the workhorse: it is what the brand reaches for when a piece needs to be packable and quiet rather than flashy. You will usually see it as Naslan Light, and almost always combined with a treatment, which brings us to the next name.
Watro
Watro is not a fabric, it is a treatment, which is why it always appears attached to something else, as in Naslan Light Watro. It makes the fabric abrasion resistant as well as wind and water resistant. In practice it is the difference between a nylon shell that is pleasant in dry weather and one you can actually wear through a Dutch winter.
Naslan Light Watro Down pieces are among the most searched Stone Island jackets there are, and they hold their price. If you see one at a low number, check it properly.
Tela Stella
The heritage one. Tela Stella is a cotton canvas that takes its cue from military tarpaulin: resin coated, dyed on both sides, then washed with pumice stone so the surface comes out worn rather than new. It is stiff at first and softens with wear, and the dyeing means the colour is never perfectly even, which is the point.
This is the fabric that connects the brand to where it started, and it is why an old Tela Stella piece with a Green Edge badge is a collector item rather than a second-hand coat.
David-TC
David means star, and the name refers to the star-shaped cross-section of the polyester yarn. The fabric is sewn first and then garment dyed at 130 degrees with an anti-drop treatment. The outcome is hardwearing and water resistant, with a slightly dry, papery surface that softens over time. You see it on trench coats and longer outerwear, where the stiffness works in the garment's favour.
Raso Gommato
Long-fibre Egyptian cotton with a polyurethane coating, then garment dyed. The coating makes it waterproof, and the garment dyeing takes the rigidity out of what would otherwise feel like a rubber sheet. It has a low satin sheen that reads expensive rather than technical.
Soft Shell-R
The modern one, and probably the most worn. Soft Shell-R is a three-layer construction: a stretch polyester canvas outer, a breathable wind and water resistant membrane in the middle, and a soft fleece backing against the body. The membrane holds an 8000 mm water column, which is enough for a wet commute without being a rain shell.
Newer Soft Shell-R pieces are made with e.dye Technology, where the colour is saturated into the yarn itself before weaving. Stone Island puts the saving at 85 percent less water and 90 percent fewer chemicals in the dye process. It is the piece to buy if you want one Stone Island jacket that you actually wear all week rather than keep for good.
Ghost Piece
Ghost is not a fabric at all, and this catches people out. Ghost Piece is a design approach: everything on the garment is rendered in a single tone, including the badge, the zips, the buttons and the lettering. The compass badge becomes monochrome, the same colour as the jacket.
It can be applied to almost any fabric, so you get Ghost versions of shells, knitwear and cargo trousers. Buyers either want it badly or not at all, and it is worth knowing which camp you are in before you order online, because a Ghost piece is deliberately quiet in a way a badge-forward jacket is not.
Why the names matter when you buy
Two jackets that look identical in a photograph can be a hundred euro apart because one is Nylon Metal and the other is a plain nylon shell. The fabric name is also the fastest way to check a listing against itself: the art number on the care label encodes the fabric and the treatment, so a seller describing a piece as something the code does not support is a seller worth a question.
Everything we list carries its fabric name and its art number in the description, because that is the detail that decides whether a piece is the one you were looking for. Have a look at the jackets, or come and feel the difference between Nylon Metal and Naslan in person at the shop in 's-Hertogenbosch, by appointment.
