Miraculously, we have received a rare pair of authentic M-51 field cargo pants, a representative pair of the US military. These items are harder to obtain than the successor model, the M-65 cargo pants. Its more green than the picture shows Cargo pants adopted by the US military from around 1951. the silhouette is thicker than the M-65, and its ruggedness is attractive. The action pleats on the knees create an excellent silhouette when viewed from the side. The plain OD color items of the US military vintage are very popular overseas, and are the ultimate pair that really dont come out.
