Palaka is a historical Hawaiian fabric.  Palaka is a woven cotton that dates back to the 1800s.  The word "palaka" is actually a transliteration of the English word "frock", the term used for loose fitting, long-sleeved work shirts worn by the American and British sailors who came to Hawaii.  During the 1920s, palaka was made of 100% woven cotton which was very thick and strong.  Many workers in Hawaii used this fabric in the pineapple and sugar cane fields  Today you can find Palaka clothing on Hawaiian musicians, celebrities, cowboys (paniolo), and even in parades.
