The M-65 field coat was first issued to the U.S. Armed Services in 1965 as a replacement for the M-51 field coat. The M-65 represented the culmination of field coat design, drawing on the technological developments of the M-43 and M-51 field coats used in WWII and Korea. The M-65 incorporated the bi-swing back and oversize design originally developed for the M-41 to provide more room for soldiers to carry everything from personal items to extra ammunition. The M-65 also used the covered zipper and snap front closure from the M-51 that allowed soldiers to crawl on their stomachs without the jacket opening and snagging on obstacles. The M-65 also kept the interior buttons and removable liner from the M-51 for greater warmth and versatility across different climates. Water repellent poly/cotton M-65 Jacket features a removable button-in liner, a concealed hood, hook and loop cuffs (for attachment to gloves), four snap-up pockets, and storm flap.
