At Master Supply Co., we make things the right way. Built to last, made to be worn hard, and shaped by the lives of the people who wear them. We work with natural materials that change over time, and every piece reflects a focus on purpose, detail, and honest construction.


The Natural Leather Collection
This collection features jackets made from 100% natural vegetable-tanned cowhide—leather that has not been dyed, painted, or finished with artificial pigments. What you see is the bare, untreated hide: light in colour when new, firm to the touch, and entirely raw in its presentation.


Master Supply Co. blends traditional craftsmanship with northern grit, producing leather jackets rooted in classic western and workwear traditions.
Designed, patterned, and graded in Toronto and produced in our own dedicated workshop, our jackets are made to stand the test of time — no shortcuts, no compromises.
