How We Build: Magnetic Zipper Series
Most people zip a jacket without thinking. They bring the two halves together, thread the insertion pin into the retaining box at the base, and pull. The whole thing takes about three seconds.
Now try that with a tremor. Or with one hand. Or with fingers that don't cooperate at 7 a.m.
The slider isn't the problem. Pulling a zip up a straight track is manageable even with reduced dexterity. The problem is the starting step - holding both sides of the garment steady, locating the insertion pin, and threading it precisely into the box while keeping everything aligned. That sequence of small, exact movements is where a jacket zip becomes genuinely inaccessible for a lot of people.
The magnetic zipper addresses exactly that step, and nothing else.
What Changes - and What Doesn't
The zipper mechanism is standard. The slider, the coil, the teeth - unchanged. What we use is a zip with magnets set into the insertion pin and retaining box at the base.
When you bring the two halves of the garment together in roughly the right area, the magnetic field draws them into alignment and seats the pin automatically. There's no precise threading. No need to stabilise one side while the other hand finds the exact position. The magnets do the alignment; you start pulling.
From that point forward, everything operates identically to any quality zip on any well-made jacket.
This matters because it means we're not asking the wearer to adapt to a different kind of closure. The zip works the way a zip works. The one step that previously required precision now requires proximity.
The Engineering at the Base
The magnetic elements sit at the lowest point of the garment - the most discreet location on the piece, and the one place that gets the most physical stress from repeated dressing and undressing.
Getting the field strength right required testing at both ends of the useful range. Too weak, and the magnets don't provide reliable guidance for hands with significant tremor - the benefit disappears. Too strong, and separating the two halves when undressing requires force that works against limited grip. The calibrated strength guides alignment from a short working distance without creating resistance on release.
We use sintered neodymium at this insertion point, fully encapsulated against moisture and wear. It maintains its properties through repeated machine washing at the temperatures we specify and through the kind of daily use a jacket actually sees over the years.
The zip base area is also reinforced at the seam and facing to handle the additional stress that comes with magnetic engagement - not dramatic reinforcement, but enough that the garment wears as well in year three as it does in month one.
How We Test It
The test is consistent: can a man close this jacket one-handed, without bracing against a surface, without looking directly at the base?
We test with people who actually need that to be true. People with Parkinson's-related tremor. People who've been dressing one-handed for years, with all the workarounds that implies. People whose grip is significantly reduced in the morning hours.
What they report back is specific, and it goes directly into the development of each garment. Not just whether the magnetic function works, but whether the base of the garment is cut and finished in a way that makes one-handed engagement natural - whether the hem hangs at the right point, whether the facing is stiff enough to give something to work against. The zip and the garment have to work together. We test both.
The Standard
The same benchmark we apply across everything we make: the person wearing it doesn't think about the closure.
Not "gets it on the second try." Not "manages it with some effort." Reaches for the garment, puts it on, moves on. The zip starts the way it should, every morning, without being the thing that determines how the morning goes.
That's what we're building toward with every garment in this series.
