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

Dry a tweed cap or hat by shaking off the water and leave at room temperature.


This fuller-shaped bakerboy is a wool tweed cap and is finished inside with a satin lining and a twill sweatband. The Muirfield fabric is heavyweight and durable, but it also has a breathable open weave, making it ideal for cooler months.
