The Underhill is a flat cap built from a perforated mesh panel that lets air move freely through the crown. A buckled strap sits at the back for a secure, adjustable fit, and the curved peak keeps low sun out of your eyes. Reach for it on warm-weather outings, at the coast, or driving with the window down when a full-brim hat feels like too much.

• Lightweight on the Head: The open mesh weave sits close without trapping heat, so it stays comfortable through a long afternoon outdoors.
• Adjustable Back Strap: A buckled strap at the rear lets you fine-tune the fit rather than relying on a single fixed size.
• Styling: Wear it with a linen shirt and chinos for a weekend drive, or with a polo shirt and shorts on the coast.
• Fit and Sizing: The Underhill is fully adjustable via the back strap, so one size fits most head measurements comfortably; if you're between adjustments, fasten it looser rather than tighter for all-day wear.
• Care: Spot clean with a damp cloth and leave to air dry away from direct heat to keep the mesh weave and shape intact.
