The M-65 replaced the M-51 in 1965 and stayed in U.S. service for over four decades — which is why genuine ones still surface on surplus racks like ours. It’s also why it became a civilian icon: a jacket designed to survive field use turns out to survive everything else too.
Genuine surplus vs. reproduction
Both hang on our rack, both clearly marked, priced accordingly. Here’s how to tell them apart anywhere:
- The contract label. Inside a genuine jacket you’ll find a military contract label with an NSN (NATO stock number), the contractor’s name (Alpha Industries, Golden Mfg., and others held contracts), and a date.
- The hidden hood. A real M-65 has a hood rolled into the zippered collar. Many fashion copies delete it.
- Hardware. Brass zippers, drawstring waist and hem, hook-and-loop cuffs, epaulets.
- Fabric. NYCO sateen — a nylon-cotton blend with a distinct dry hand. It softens beautifully with age.
A good reproduction — Rothco’s is the standard — is a perfectly good jacket. It just shouldn’t carry a surplus price or a surplus story. We label ours so you never have to guess.
Sizing: read it like the Army does
Military sizes pair a chest size with a length: Small-Regular, Medium-Long, and so on. Two things to know:
- The cut is intentionally roomy — it was made to layer over a field uniform and liner. Your usual size gives the classic loose silhouette; one size down gives a closer modern fit.
- “Long” adds body and sleeve length, not width. Over 6’1″? Go Long.
Field jacket care
Cold wash, hang dry, and skip the iron. The fading and softening is the point — a genuine M-65 with patina is worth more to most buyers than a dead-stock one. If yours came with a previous owner’s history (stenciled name, unit patch shadows), consider leaving it. That’s the part you can’t buy new.
What it costs here
Genuine surplus M-65s typically run well under what vintage shops charge, and condition is graded honestly — “as-is” means as-is, and we’ll tell you upfront. The rack changes weekly. Browse the military surplus department, or come dig in person at either main store.
