Mark-IV

The Master Supply Co. Mark-IV jacket is made from full-grain Accelerust buffalo leather, renowned for its unique patina potential that reveals a rich cognac brown core as it ages. Our signature pleated trucker silhouette, celebrated for its timeless appeal, is enhanced with symmetrical button placement, contrast pleat stitching, and familiar details like the western yolk and embroidered chest pockets.

For added warmth during colder months, the jacket includes a shearling collar and a 100% cotton buffalo plaid liner with light insulation. Every aspect of the Mark-IV reflects our dedication to quality and craftsmanship, embodying our journey towards perfecting this iconic design.

Please note: Each shearling collar, made from natural fur, may vary slightly in color or texture. The rapid patina development of the Accelerust leather is a deliberate feature, designed to evolve uniquely with wear. The leather’s core is dyed a deep cognac brown, with a pigmented black exterior that gradually wears to reveal the brown beneath, telling the story of your adventures. The Mark-IV is not just a jacket—it’s a personalized symbol of our shared journey, designed to evolve with every wear.

Each jacket is designed in Toronto and built in our own dedicated workshop in Pakistan. We oversee every step — from pattern drafting to leather selection to final inspection. Every jacket is individually photographed, measured, and quality-checked before leaving the shop. We produce in small batches using full-grain leathers, custom hardware, and offer complimentary custom sizing on all builds.
