A precursor to the iconic M-65 Field Jacket, the original M-51 has its own vaunted place in the history of military-issued field jackets, bringing about thoughtful innovations to help better equip soldiers for the conflicts of the era. Built with versatility and everyday functionality in mind, The M-51 featured a convenient zipper and snap fasteners, and it remained a popular choice among both soldiers and civilians even after future revisions emerged. Our take on this classic maintains its inimitable looks and feature-rich design, but we've upgraded the materials with Responsibility in mind. The M-51 is a sharp, substantial piece on its own, but should you need additional protection from the elements, pair it with the attachable ALS/92 for the full experience.


While our take on the M-51 is true to the original's function-focused design, we upgraded the materials to keep it from feeling like a relic. The shell itself is made from a soft, resilient 10-oz 100% organic cotton reverse sateen—a touch heavier than its inspiration, and a whole lot easier on the environment. The liner is made from 6-oz organic cotton and adds just enough heft to keep things cozy without constricting your movement. Other killer features include a wealth of handy storage options (expandable chest pockets, two internal zippered pockets, and more), antique YKK hardware throughout, and a storm welt along the front enclosure to keep the elements at bay.
