This vintage cap was made by Knox hats in the late 1920s or early 1930s as part of the uniform of the United States Olympic team. It’s difficult to say with 100% certainty, but this looks consistent with what was worn at either the 1928 St. Moritz or the 1932 Lake Placid games. It is made from white felt in a traditional flat-cap style, with an embroidered US Olympic shield crest consistent with the early games. The cap has a cream colored leather sweatband of the type typical of the late 1920s and early 1930s. The deep embossing is also typical of what Knox was producing in this era. The style of brim is something I have never seen before. Usually the brim on these flat caps is a separate piece, usually with a snap on the top. This is interfaced inside for a degree of stiffness, then decoratively stitched, presumably so that the cap can be rolled up and stowed easily. There is a remnant of the original size tag, but not enough to tell the size. The sweatband measures 22″ in circumference.
