Tilley LTM3 Airflo Hat (Size: 7 5/8, X-Large)

Tilley hats are designed to sit comfortably low on the head. The proper fit should be slightly loose, as gravity will keep your Tilley in place.

Step 1: Wrap a string around the widest part of your head, located 1 to 2 cm above the top of your ears and brow line.

Step 2: Determine the measurement with a ruler, then add 2 cm to the total, for comfort.

Step 3: Convert that final measurement into your hat size.
