A blouson that ages like fine wine—faster than you’d think.

The MARK-IV isn’t just another leather jacket; it’s a celebration of four years of quality manufacturing from Master, a Canadian brand that understands the alchemy of leather. This piece is cut from full-grain buffalo hide, treated with an Accelerust process that speeds up the patina, giving it the character of a well-worn favourite in just weeks. The result? A rich, cognac-brown heart that emerges beneath the black, unique to every jacket. It’s a trucker silhouette at its core—timeless, rugged, and effortlessly cool—but with a few deliberate twists: symmetrical buttons, contrast stitching, and a collar lined with genuine shearling for warmth without bulk. Lightly insulated, it’s built for year-round wear, bridging the gap between vintage charm and modern edge.

Designed for those who let their clothes tell a story.

The MARK-IV doesn’t just look lived-in; it *becomes* lived-in, and quickly. The buffalo leather, known for its durability and natural grain, softens with wear while developing a patina that’s as individual as the person wearing it. The shearling collar isn’t just for show—it adds a layer of insulation that makes this jacket as practical as it is stylish, whether you’re braving a crisp autumn morning or a chilly urban evening. The trucker cut, with its straight lines and slightly boxy fit, nods to classic workwear, but the contrast stitching and symmetrical button placement give it a contemporary twist. It’s the kind of jacket that pairs as well with raw denim and leather boots as it does with a simple tee and sneakers, making it a versatile staple for any wardrobe.

Master isn’t just another name in leather—it’s a brand that’s carved out a reputation for blending heritage techniques with modern innovation. Based in Canada, where rugged durability meets refined quality manufacturing, Master has spent the last four years perfecting pieces that don’t just last but evolve. Their approach? Respect the material. Whether it’s full-grain buffalo hide or shearling, they let the leather speak for itself, enhancing its natural qualities rather than masking them. The MARK-IV is a testament to that philosophy: a jacket that’s built to age, not just endure.
