For the best fit, measure the circumference of your head
just above your ears and eyebrows, then compare it with our sizing guide. A
well-fitting hat should feel secure without being tight and sit comfortably throughout the day.
A Panama hat is handwoven from toquilla straw and is known for its timeless style and breathable finish. A summer trilby has a shorter brim and a more contemporary
shape, making it a versatile choice for smart-casual dressing.
For summer occasions, classic Panama hats are an elegant choice for garden parties, regattas and weddings, while a refined boater or smart fedora can also suit more formal dress codes. Choosing a hat in a neutral shade ensures it pairs effortlessly with tailoring.
Always handle your Panama hat by the brim rather than the crown to help maintain its shape. Store it somewhere cool and dry, avoid prolonged exposure to heavy rain, and use a soft brush to remove dust when needed. With the right care, a quality Panama hat can be enjoyed for many summers to come.
