Slice, Wide Brim Hat
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.
Oversized 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.
