How to Detect an Authentic M65 Field Coat: A Guide for Buyers

The M65 Military Field Coats are one of the most iconic jackets ever. First introduced by the U.S. military in 1965, this jacket offers durability, warmth, and utility in harsh environments. 

The coat remains a staple in military surplus collections and fashion circles. However, with the rise of reproductions and knockoffs, knowing how to identify an authentic M65 Field Coat before purchasing is essential. This comprehensive guide will walk you through the key features, materials, and tips to spot the real deal.

1. Understanding the History

Before diving into specifics, it's essential to know the origins of the M65 Field Coat. The jacket was developed to replace the M51 Field Jacket, with added features to improve functionality. 

Designed for the U.S. Army during the Vietnam War, the M65 became synonymous with ruggedness and adaptability. Knowing its historical context helps identify design elements unique to the authentic versions.

2. Manufacturer Labels

One of the most reliable ways to verify authenticity is by checking the manufacturer's labels. Genuine M65 Field Coats were produced by several contractors, including Alpha Industries, Golden MFG, John Ownbey Co., and Propper International. The labels should include:

• Manufacturer name

• Contract number

• NSN (National Stock Number)

• Size Details

• Care instructions

Look for precise, durable label stitching—blurred or poorly printed text is a common sign of fakes.

3. Fabric Quality

Authentic M65 Field Coats are crafted from a heavy-duty cotton-nylon blend. The outer shell typically consists of 50% cotton and 50% nylon, designed to be water-resistant and breathable. 

The fabric should feel thick and robust, with a matte finish. Reproductions often use thinner materials that lack the sturdy feel of the original.

4. Zipper and Snap Buttons

Pay attention to the hardware. Genuine M65 Field Coat features brass zippers from reputable brands like Scovill or Ideal. The zipper should glide smoothly without catching. 

Snap buttons will be heavy-duty metal, typically marked with YKK or RAU Fastener Co. Modern replicas often use lightweight plastic or generic metal snaps.

5. Hood and Liner Details

The M65 Field Coat features a hidden hood concealed in the collar, made from a lighter cotton-nylon blend. The collar should close with two metal snaps. 

Additionally, authentic M65 jackets have button-in liner attachments to add extra insulation for cold weather. If you're buying a coat with a liner, ensure the liner is quilted and fits snugly inside the coat.

6. Stitching and Construction

Authentic M65 Field Coats are built to last. Check the stitching along the seams—original jackets have straight, even stitching with reinforced seams at stress points. Loose threads, uneven stitching, or flimsy seams are red flags that indicate a reproduction.

7. Color and Fading

Most original M65 Field Coat comes in Olive Green (OG-107), though some later versions were produced in black or woodland camouflage. 

Vintage coats will show natural fading, especially around seams and edges. Excessive fading or strange color variations might signal a reproduction or poorly maintained jacket.

8. Sizing and Fit

Authentic M65 Field Coats were made with a boxy, oversized fit for layering underneath. Check the size label inside the jacket—vintage M65s often come in Small, Medium, large, or extra large rather than modern numeric sizes. If the fit feels too slim, it's likely a fashion reproduction rather than an original.

9. Price and Source

M65 Field Coats are widely available. However, price can be a good indicator of authenticity. Genuine vintage jackets typically range, depending on condition and rarity. 

Be wary of suspiciously cheap listings, especially on online marketplaces. Buy from trusted military surplus stores, vintage clothing dealers, or specialized retailers that can provide provenance details.

10. Final Tips

• Always request detailed photos before buying online.

• Ask for information on the jacket's history or previous owner.

• Compare the jacket's details against reference photos from trusted sources.

• Don't be afraid to reach out to collectors or forums for advice.
