the MAC Hat
Try contacting Gieves and Hawks (Think it's Saville Row) and ask for a Garry Carr.
He sells the Mac hat that was designed by one of our colleages who is very much into his tweed, uniform, old england, drives a morgan etc.....
It is designed to be rolled up and put in your flying suit pocket without being creased or damaged. Excellent for us chaps who do not want to wear a beret when we go for a night stop somewhere.
However it will set you back £205, though 10% goes to RAFA.
It is worth it and is the copy of the hats you see in the old WW2 movies, edges falling nicely around your head as opposed to the Cranwell version of the Russian General's hat.
Wokawoka.
