Celebrate the RAF with this iconic cap dedicated to the famed roundel - the red, white and blue symbol used on British aircraft since 1915. They were first created in WW1 to help identify friends or foe in the midst of combat. The cap is 100% brushed cotton twill, decorated with a felt logo and direct embroidery. It's one size fits all with a velcro enclosure. A great gift idea for any lover of military aviation.
