Darcy Blue Flat Cap

This hat is not designed to be worn in the rain. Should you get this style wet, it should be dried at room temperature, never on top of a radiator. Cotton and linen hats and caps should not be stored in direct sunlight. 


The cap is made from 100% linen and is finished with an internal cotton sweat sweatband, so it stays firmly in place.  It is fully lined with a breathable cotton lining and features our famous label.

Styling & Fitting

Hatter's Tip: As this is a wider flat cap, it’s best to style it at an angle.
