Adjustable Green Baseball Cap

Our adjustable, durable, green baseball cap is made from luxurious wool for a lightweight and cool feel in the warmer months.

With a classic British aesthetic, this baseball cap offers chic and contemporary styling for smart casual summer wear.

Adjustable Green Baseball Cap


  • Peak Length: 7 cm
  • Peak Diameter: 17.5 cm

This cap 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.


The shell is constructed with 100% wool from the United Kingdom. The inside front panel is lined with 100% cotton while the remainder is left unlined to keep it breathable.

Styling & Fitting

An adjustable buckle allows you to find the perfect fit, and an embroidered Lock & Co. logo is featured on the left side of the cap.

The cap is the perfect addition to your spring and summer looks and is also available in red and brown.
