1930s Optimo Vintage Straw Panama Hat

Find your perfect fit in two steps: measure your head or use a hat you already own, then convert the result with our size chart.

How to Determine Your Size

If you already have a well‑fitting hat: check the size on its tag and use the conversion chart below to match it to a head measurement.

Quick Measuring Options

• Option 1: Measuring Tape
• Measure as described above, then use the chart to select your size. Between sizes? Size up and add padding if needed.
• Option 2: Snapback Trick
• Adjust a snapback to your most comfortable fit, note its labeled size/setting, and map it to our chart. If between sizes, size up and pad.

Sizing

• S / 55 CM
• Our smallest standard size. Best if your head measures 53–54 cm.
• M / 57 CM
• Ideal for the average head size; our recommended “standard” fit.
• L / 59 CM
• Great for larger heads; the go‑to large size.
• XL / 61 CM
• Available in most styles and sold exclusively online; extra room when you need it.

Fit Tips

• Fit is personal—choose how you want your hat to sit and feel.
• For extended wear (4+ hours), a slightly looser fit that sits lower can be more comfortable.
• Shape and style affect fit. Always check each product’s size and fit notes to ensure the best choice.
