I am currently relearning a bit of armor making after having to stop for many years due to medical problems. I have always like the samurai, so for a small project I have decided to try a bajo-jingasa. I am relearning a bit of terminology as well. This style is called a tetsu bajo jingasa= Iron(tetsu), Riding(bajo), camp hat(jingasa).
Screen caps from the movie "Shogun" showing how the bajo-jingasa is worn.
