Vtg 50s-60s Deadstock Washington Mills Navy Blue Thermal Lined Hoodie with a kangaroo pocket and a stainless steel YKK zipper. SZ S 34-36. The tags are missing, but this is a deadstock item from an old store. It has a unique look, with white threads in the pattern, although it's not particularly textured. In great unworn shape! The presence of a WPL number (3107) and a YKK steel zipper on a sweatshirt strongly indicates a manufacturing date between the late 1950s and the early 1960s. The WPL (Wool Products Labeling) system was active from 1941 to 1959, and the number WPL 3107 is associated with the Washington Mills Company.
