The OG108 wool shirt, which began to appear in the Korean War, was still produced in the 1980s. As the middle-temperature layer of field clothing (such as M51, M65), it is very good. But, military version wool fibre is thick, and the comfort is not strong.
This OG108 shirts have a soft touch and can be directly contacted with the skin. The color is close to the military version, and the product is slightly green. Engineering armband with an Alaskan Bear patch (can be removed if you don't like it)
