1940s Monarch Horsehide Leather Jacket – Medium (42)

Monarch Milwaukee was a powerhouse in the golden era of American leatherwork—when jackets weren’t designed to follow trends, but to outlast them. Built in the 1940s and cut from thick, genuine horsehide, this jacket was made for the kind of men who needed their gear to work as hard as they did—outdoorsmen, labourers, adventurers. It’s tough, functional, and unapologetically built to survive.

The deep brown horsehide wears the kind of patina that only decades of honest use can create. Its grain is bold, its weight substantial, and every seam is double-stitched with purpose. The four-pocket front layout is classic Monarch—functional and well-balanced—while the rayon lining inside adds a layer of comfort without compromising durability. Five buttons have been replaced with period-correct pieces, perfectly matched in tone and feel. The label says “Genuine Horsehide,” and it means it.

Professionally cleaned and conditioned, the jacket’s surface has been revived without sanding down its story. The leather remains flexible, strong, and rich with natural tone variation. The original rayon lining shows minor wear consistent with age but requires no repairs. With no structural damage to the leather, this piece needed only restoration—not intervention.
