      LONGEVITY


      Lock & Co. Hatters is the oldest hat shop in the world and the oldest shop in London. Our passion for hats is boundless and our knowledge unrivalled. For 350 years, Lock & Co. has worked with the finest felts, tweeds, cloth, and cashmere, sourced exclusively from around the world.
      Drawing on our unique British heritage and craftsmanship, we create both
      traditional and contemporary hat designs, with scrupulous attention to quality and fit. Our hat shop was established in 1676, making us the oldest hat shop in the world and the oldest shop in London. Every Lock & Co. hat purchased is carefully and expertly hand-prepared in our London shop by one of our Hatters, before it leaves through our famous green front door at No. 6, St James’s Street.

      For centuries, we have supplied some of history's best-known figures with hats, including Admiral Lord Nelson and Winston Churchill. We created the world's first bowler hat (known to hat aficionados as the 'coke'), and to this day our styles remain fresh, trusted and timeless. Royal Warrants attest to Lock & Co.'s commitment to hat quality that is trusted and respected; everything that
      you would come to expect from Lock & Co. – the home of hats since 1676.
