You can never really wear out one of these…
When I was a kid, as a military brat, I inherited a very well-traveled OD M65 Field Jacket and wore it throughout junior high and high school. It finally came up missing at a party in college and I suspect that somewhere it remains, probably in the closet of a hipster, with mustache wax on the collar.
Later, in the state guard, I got one of my own woodland camo model– that my son now wears occasionally– before they were phased out altogether in 2009.
This Vietnam-era OG-107 classic, which has long since past its (official) wear-out date, is still in use at the Washington Naval Yard with the 8th & I Marines.
