Measurements based on a size EU 59 cm flat cap:

  • Peak Length: 5 cm
  • Diameter: 21 cm

Steam from a household kettle and a hard bristle hat brush will help banish any dust and dirt. Brush the hat using short strokes.

Dry a wool cap by shaking off the water and leave at room temperature.


This fully lined cap is made from Escorial wool; a rare and luxurious wool that can only be found in small quantities in Australia and New Zealand today. The Escorial fibre is similar to a curled spring, and when stretched during the manufacturing process, its natural memory returns it to its original curled state. This is what distinguishes Escorial hats as lightweight and resilient.

Styling & Fitting

Generally, flat caps tend to be worn straight on the head so that they lie about 1 inch above the eyebrows.
