1960s Army Greens Class A Enlisted Uniform List - UNIFORMS ...
The coat, Army Green and Trousers, Army green came in AG-44 which was all wool, or nearly all wool, and the AG-344 which was a poly/wool blend. The AG-44 was dropped sometime in the late 70s or 80s. I was issued both in 1973. We called the AG-344 "summer greens" and the all wool "winter greens" but I don't think those were official names.
