Decrum — Men's Leather Jackets, Since 2015
A slim moto jacket stripped to its cleanest lines — no excess, all intent. This men’s cognac brown leather racer jacket runs close to the body with a mandarin collar and a straight centre zip, the refined cousin of the classic biker: sharp without the hardware pile-on. Cut from 100% real lambskin, it holds its shape and its edge for years rather than seasons. Weekday polish or weekend ease, it does the job of three jackets and never looks like it’s trying. Best of all, cognac is a colour that improves with age — every wear deepens it.
Handcrafted in Decrum’s own workshop and sold direct — maker-to-wardrobe, without the retail markup a racer jacket 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% real lambskin gives a slim jacket its close, second-skin fit without stiffness — light on the shoulder, quick to warm to the body. In cognac, the leather’s depth really shows: a warm mid-brown that catches light across the grain and takes on a richer patina the more it’s worn. It breaks in rather than breaks down, the surface softening and the colour deepening season on season. This is a jacket that looks better broken in than box-fresh.
A slim racer silhouette built for a clean line — a mandarin collar that sits sharp without a lapel, and a sturdy YKK centre zip straight up the front. Four zip pockets — two at the chest, two at the sides — keep the front minimal and everything secure. Trim through the shoulder and body, it reads streamlined rather than bulky, moto in spirit but easy to wear off the bike.
Over a white tee and dark denim it’s pure clean moto; over a shirt it sharpens up for the evening. Cognac is the versatile middle of the brown family — warmer than black, richer than tan — and pairs as easily with grey and cream as with indigo. It brings colour and character without ever shouting.

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!
