Sailor hats were first introduced by the Russian navy in September 1811 as a part of their uniform. During this period, the Russian navy wore uniform similar to the military. The bezkozyrka (non-peaked hat) was introduced instead of peaked cap as it was more practical for marine conditions. French navy’s version had a red pompom on top of the cap, which was introduced in 1848. Whereas a white cap with an uptight brim is worn by the United States navy.
