1940s/1950s Vintage Two Tone Football Jersey Pullover Shirt

This is a replication of a 1950s USN N-1 undershirt. Originally used for training wear within the US Navy in the 1950s, the thick bib-like patch over the chest and back constructed with 4 needle stitching is to improve the durability of the garment. It was made of a heavy-duty fabric blended with wool and cotton. Its advantage is that it is very warm, but the disadvantage is obvious, it is terrible to wear skin feeling.
