Why Berlin Is an Interesting Place for Sportswear — and What That Has to Do With M23
Share
Berlin isn't a fashion city in the classic sense. No Paris, no Milan. No glamour, no red carpets, no dynasties. What Berlin has is something different: a culture that puts function over form, that experiments rather than conserves, and that has always treated clothing more as a tool than a status symbol.
That's not an accident — and it explains why an activewear label like M23 comes from Berlin and not Frankfurt or Munich.
What Berlin Production Culture Actually Means
When we say "produced in Berlin," we don't mean a warehouse in some industrial estate on the outskirts. We mean a manageable production structure with real contact people, direct quality control, and short routes between design and finished product.
That has practical consequences:
Quality control without delay. If something is off with a cut, we notice immediately — not six weeks into a shipping lead time from another continent.
Small batch sizes possible. Berlin production allows us not to produce in bulk quantities. That means less overproduction, fewer leftover stock, no seasonal goods that need to be discounted.
Personal accountability. People who know their production partners personally make different decisions than people entering an anonymous order into a system. That's not a sentimental point — it's a structural question of incentives.
Berlin as a Testing Ground for Activewear
Berlin is one of the most active cities in Europe — not in the tourist sense, but in the literal one. Outdoor fitness groups in Görlitzer Park, Hyrox training in Kreuzberg, beach volleyball at Badeschiff, running routes through Treptower Park. These aren't fringe activities. They're daily life for a large part of Berlin's population.
That makes Berlin an honest testing ground for sportswear. People who train here train outdoors, in variable weather, on different surfaces, often several times a week. What doesn't work shows up fast.
M23 products come out of that context — not from a sterile design studio with mood boards and trend reports, but with direct connection to the people wearing them. Marci, who founded M23, runs outdoor fitness groups in Berlin herself. That's not a marketing detail. It's the foundation on which product decisions are made.
What Berlin Production Culture Is Not
Here's the counterpoint to the romanticised image:
Berlin isn't a solution to all production questions. Not everything can be made here — and not everything needs to be. Our production in Bulgaria complements Berlin production where capacity and specialisation make it sensible. Bulgaria has a long textile tradition, skilled production, and geographic proximity that keeps transport routes short.
"Produced in Berlin & Bulgaria" isn't an excuse or a compromise. It's the honest description of a production structure that emerged from concrete decisions — not from a branding meeting.
What This Means for M23 Products
Every product in the M23 range is the result of decisions made in Berlin — about material, cut, colour, function. Production happens in Berlin and Bulgaria, with materials we know and whose origin we can name: organic cotton from Turkey, recycled nylon from Italy.
That's not a particularly heroic business model. It's a functional, honest one suited to the demands of activewear.
Berlin hasn't made us glamorous. But it has kept us grounded — in the most literal sense. In the park, on the pavement, in every kind of weather.
If you want to know what's concretely in M23 products — materials, cuts, intended uses — you'll find it on every product page in the shop. No promises, just facts.
