Twill Gabardine with a Hard-Touch Finish
Crafted from a blend of fine merino wool and hard-type raw wool known as "Gari," this medium-gauge worsted yarn twill gabardine offers a structured, durable feel.





TYPE OH
Round or square face shapes

Designed with added volume around the crown and a wider brim to balance the appearance of larger facial features.

TYPE U
Short height from eye line to crown

Adjusted panel height and volume create a proportionate look for shorter head heights.

TYPE Y
Wide temples tapering toward the chin

With reduced side volume and carefully balanced brim length and angle, this design harmonizes features for a balanced appearance.

TYPE I
Narrow, elongated face shapes

The crown is smaller, and the brim is tailored in width and length to match the face's proportions, avoiding an overly elongated look.









Simple Design for Any Occasion
The brim is soft and unstructured, making it easy to pack in a bag without worrying about creases.

The back features two embroidered circles as a subtle design accent. Its clean, minimalist design makes it versatile for any style.



Ribbed interiors ensure a comfortable fit without tightness.
