LangerChen long wool trench coat MILPORT – sustainable, windproof & elegant
This is the kind of coat you’ll want to put on immediately and never take off. Why? Because it has it all. Warm, elegant, sustainable and practical – without even a hint of that synthetic feel. The LangerChen MILPORT is the ultimate winter coat for women who love style and comfort, but with honest materials. Think of the smartest technical features, but executed in pure wool and organic cotton. Sound good? It gets even better! Read on!
Sustainable elegance with a twist
What makes this long wool trench coat so special is the combination of minimalist design and clever details. The outer layer of 100% organic wool is naturally water-repellent (thanks to lanolin – that natural fatty layer found in wool). Is it drizzling? No problem. A heavy downpour? Okay, to be honest: the seams might get wet. But hey, hang it inside out overnight and it’ll be as good as new. It’s not a raincoat, after all.
Windproof thanks to an innovative membrane
And here is the genius part: between the outer layer and the lining, there is a polyurethane membrane. That sounds technical – and it is – but believe me, this is what makes the coat truly unique. You get the warmth and luxurious look of wool with the comfort of windproof material. So, whether you are cycling through Rotterdam or strolling along the beach: the wind won’t stand a chance.
Soft lining, no sweaty business
The inside is lined with 100% organic cotton jersey. That means: no sticky, sweaty fabrics, just breathable comfort. Exactly what you want in a winter coat that you wear every day. And believe me: you will.

Maintenance tip
Let your coat air out regularly and hang it up to dry after a rain shower. Wool is largely self-cleaning – washing is rarely necessary. And never put it in the dryer; that would be a real shame.

Why does my LangerChen coat have a membrane?
You can’t see it, but it’s there: a very thin layer of polyurethane (PU) incorporated into the coat. We call that layer a membrane, and it’s essentially the secret superpower of your coat.
What does it do? Very simply: rain and wind cannot get through, but your own warmth and perspiration can escape. This keeps you dry on the outside and comfortable on the inside. So you don’t get that stifling "raincoat" feeling.
Why polyurethane?
I hear you thinking: “But PU, isn’t that plastic?” Correct. LangerChen chooses this consciously, because the alternatives are often even worse for people and the environment. Think of Gore-Tex or other membranes with fluorocarbons (PFCs) – they are practically indestructible, but unfortunately also toxic to nature. Polyurethane is currently the most responsible choice for making a coat sustainably waterproof without exposing you to harmful substances.
How sustainable is that, really?
A PU membrane is not biodegradable, but because LangerChen works with sturdy, timeless fabrics and top-quality finishes, you will wear the coat for years. And that is what makes the difference: one high-quality coat that you wear for ten years is many times more sustainable than three fast-fashion rain jackets that fall apart after one season.
How do you care for such a coat?
-
Wash as little as possible (that saves on wear and energy).
-
Use a mild, ecological detergent.
-
Simply hang the coat to dry after a rain shower; that is usually enough.
This way, your membrane continues to work optimally and keeps your coat looking great.
