Sienna Fedora
How to Measure Your Head
Place a flexible measuring tape or string 1 cm above your ears and across the mid-forehead. Keep the tape or string level and snug, but not too tight. If using string, measure the length in centimetres to know your size.
Finding Your Size
Once you've measured your head, match your measurement to the closest size range below.
For example:
- If your head measures 58 cm, you'd likely wear a M/L.
- If it's 60 cm, you're best suited to a L/XL.
- Each size covers a range to ensure the best possible fit.
- Refer to the size chart below (Figure 1) to see which category your measurement falls into.
Between Sizes? Round Up
If your measurement falls between sizes, size up and choose the larger size for all-day comfort.
Fine-Tune With the Internal Size Adjustment
Most styles include an internal drawstring or Comfy-Fit Clip elastic band that lets you tighten up to 1.5 cm smaller without altering the hat’s structure.
| Symbol | Measurement in cm | Description |
| S/M | 55 cm, 56 cm, 57 cm | Small to Medium |
| M/L | 57 cm. 58 cm | Medium to Large |
| L/XL | 59 cm, 60 cm, 61 cm | Large to Extra Large |
The sun hats in our collections provide an easy way to adjust the size in order to ensure a perfect fit. They come either with an inner drawstring or a Comfy-Fit elastic adjustment. You can wear your hat even in windy conditions!
