National flag of Israel - Authentic version Trucker Hat

The blue stripes are intended to symbolise the stripes on a tallit, the traditional Jewish prayer shawl. The portrayal of a Star of David on the flag of the State of Israel is a widely-acknowledged symbol of the Jewish people and of Judaism. The Israelites used a blue coloured dye called tekhelet; this dye may have been made from the marine snail Murex trunculus. This dye was very important in both Jewish and non-Jewish cultures of this time, and was used by royalty and the upper class in dyeing their clothing, sheets, curtains, etc. (The dye from a related snail can be processed to form Tyrian purple called argaman.)
