The state flag of Hawaii consists of a square (canton) in the upper left corner of the flag which contains the Union Jack, the national flag of the United Kingdom. The canton represents the period Hawaii was associated with the British Empire. The field consists of eight horizontal stripes - white, red, blue, white, red, blue, white, red - which represent the eight major islands of the state - Hawaii, Oahu, Kauai, Kahoolawe, Lānai, Maui, Molokai and Niihau.
Hawaii flags for outdoor use are constructed of a durable nylon fabric especially developed for flag use. Nylon's tight weave provides maximum beauty and flyability as well as brilliant, fast colors. Its weave helps shed pollution, dirt and grime that the looser weave alternatives absorb. Nylon is water repellent and mildew resistant.
