Constructed with strategically placed mesh fabric, it delivers superior breathability to keep your head cool and dry.

Why We Love It

Care & Maintenance

To preserve the flexible core of the brim and the structural integrity of the mesh, please observe the following care guidelines:

Drying: After washing or heavy perspiration, always re-shape the cap and dry it in the shade. Avoid leaving it crumpled while wet, and keep it out of direct, intense sunlight to protect the fabric and water-repellent finish.
(Please refer to the interior garment tag for specific care symbols regarding water temperature, washing methods, bleaching, and dry/wet cleaning).
