Monaco Hat

The Monaco trilby-style hat will add a dash of panache to your summer wardrobe.

This dapper hat is made from cool calico and adorned with our Lock & Co. house ribbon. This makes it the perfect summer accessory for social occasions, while a pure cotton lining and sweatband complete the look.

  • Brim Length: 6 cm
  • Crown Height: 9.5 cm
  • Band Width: 4.5 cm

Steam from a household kettle and a soft bristle hat brush will help remove dust and dirt. Brush the hat using short strokes.

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 hats and caps should not be stored in direct sunlight.

At Lock & Co., we sell the finest hats and caps. To achieve this, we pay particular attention to specific hat characteristics - style, fit, durability, and materials. We share these characteristics with you for each hat to help you decide on the perfect choice.

Find Your Size and Style

At Lock & Co. we offer a wide selection of styles of hats. What defines a hat style is its form: overall shape, height/shape of the crown, width of the brim, and material type. These define a style e.g., Fedora, Trilby, Panama, Cloche, Tweed cap etc.
Lock & Co. hats are made of the finest quality material. These can range from exclusive Escorial wool, Scottish Tweed, and cashmere to Toquilla straw for our Panama hat.
Standard Brim
Different styles of hats have different shapes to them, including classic, fuller, narrow, and standard fits, or with an oversized or a wide brim or sporting a particular shape - bell, birdcage, etc.
