Decrum — Men's Outerwear, Since 2015
Some coats make an entrance; this one makes it every time. The Jackson is a men's black leather long coat in 100% real lambskin — a full-length duster cut for drama and built to be lived in. Because lambskin is light and supple, a coat this long drapes clean and moves with you instead of weighing you down. In black it reads sharp over a suit and easy over a knit. You buy it once and wear it for years — and it only ever looks more like yours.
Handcrafted in Decrum's own workshop and sold direct — maker-to-wardrobe, without the retail markup a coat like this usually carries. We've built leather this way since 2015: real hide, honest construction, no faux and no shortcuts. You pay for the lambskin and the hands that shaped it, not the names in between.
100% genuine lambskin, chosen for how it carries length. Finer and lighter than heavier hides, it stays buttery-soft and fluid where a stiffer leather would feel like armour — so the coat drapes and swings, breaking in rather than breaking down and deepening in character with every season. This is the opposite of disposable fashion: a material with a memory.
A full-length duster silhouette with a clean button closure and an adjustable belt to shape the waist — presence without bulk. Four pockets, two outside and two inside, keep it ready for a real day, and a regular, true-to-size fit layers easily over a suit or a heavy knit. Office to street, weekday to weekend, it holds its line wherever you take it.
Belted over a suit for the sharp version; open over a roll-neck and denim for the easy one. Full-length black is the quiet power move — it finishes an outfit and lengthens the whole line, without ever shouting over it.

Great product
Product as advertised - good quality, colour matches the picture. Good communication prior to shipping - asking for clarity on sizing etc. Measure yourself or have someone else measure yourself for sizing - the products are true to their size.
I was a bit sceptical of ordering…
I was a bit sceptical of ordering online but I did. Received jacket and was beautiful. It was so soft and light but the quality was exceptional. I ordered the wrong size and communication was exceptional and fast so received new jacket quickly and very happy with service. Very happy I ordered from this company 😊
Highly advanced in customer experience
Decrum is highly advanced in customer experience from initial contact to purchase exactness to delivery and follow up — an example for healthcare industry standards, surgical in one word. I'm not returning my exact-fit, great-price leather jacket.
The jacket is a beautiful color and quality!
The jacket is a beautiful color off white, very soft and thicker leather than I expected for a lambskin hide. It is comfortable and looks great! Excellent communication during the process also! Ticks all the boxes — I was hesitant at first to order a leather coat online and happy I took the risk. Great quality, and a smooth, informed process including follow up! Thank you Decrum!

Yes. Decrum.com is our dedicated US storefront. While we are a global leather specialist with over 50,000 customers worldwide, this site is built specifically for our American customers — with pricing in USD, US sizing support, and shipping routes direct to all 50 states. We have been trusted by leather jacket buyers across the US since 2015. Read our full brand story here.
We use 100% Genuine Grain Leather, specializing in premium Lambskin and Cowhide. We do not sell faux, vegan, or PU leather. Every Decrum jacket is a natural product designed to be breathable, durable, and improve with age — the more you wear it, the better it looks and feels. If genuine leather matters to you, it matters to us too.
Yes, shipping is free on all US orders. Standard delivery takes 4–6 business days, and express products arrive in 2–4 business days. We ship via DHL, FedEx, or USPS with full tracking. You will receive a tracking link by email as soon as your order is dispatched — or you can check your shipment status anytime on our Track Your Order page.
Our jackets are designed with a modern, tailored fit. We recommend measuring your chest in inches and matching it against our Size Guide — we provide exact chest measurements so you can shop by body measurement rather than guessing by label. For a looser fit or if you plan to layer over a hoodie, always go one size up. Still unsure? Contact us at our contact page and we will advise before you order.
We offer free returns for all US customers. If your jacket is not the right fit, initiate your return within 30 days of delivery through our Return & Exchange page — we provide a prepaid return shipping label so the process is completely free. Items must be unworn, unwashed, and have tags attached. Once your return passes inspection, your exchange ships immediately.
