The inspiration for this cap comes from the one used by mechanics from the US ARMY in the 40's. The fabric is charcoal grey duck, the same one used in our Tabby's Jacket. It's 11.2 oz made of 100% cotton.
It might be difficult to know the right color in the pictures, please refer to the third pic of the jacket.
