The Missouri state flag has three large stripes symbolic of the people of the state - the blue stripe represents vigilance, permanency, and justice, the red represents valor, and the white stripe symbolizes purity. The Missouri coat-of-arms appeared in the center of the flag, signifying both Missouri's independence as a state, and its place as a part of the whole United States. Having the coat-of-arms in the center of the national colors represents Missouri, as she is - the geographical center of the nation. By mingling the state coat-of-arms with the national colors of red, white, and blue, the flag signifies the harmony existing between the two. Twenty-four stars surrounded the coat-of-arms, representative of Missouri's position as the 24th state admitted to the Union.
Missouri 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.
