Learn how to measure your head for a Rumpl unstructured hat, understand fit nuances, and decide if the Trademark Unstructured Hat in Driftwood is right for you.
Quick answer
For the best fit with Rumpl's unstructured hats, measure your head circumference just above your ears and eyebrows, then compare it to the hat's size range. Unstructured hats like the Trademark Unstructured Hat in Driftwood fit slightly looser than structured caps, so if you're between sizes, choose the smaller one for a snug feel.
Why fit matters for unstructured hats
Unstructured hats, like the Trademark Unstructured Hat, lack the stiff front panel found in structured caps. This gives them a relaxed, slouchy look that molds to your head over time. However, it also means the fit depends more on the crown's depth and the brim's curve. A hat that's too loose may shift or blow off, while one that's too tight can cause discomfort.
How to measure your head
Use a flexible measuring tape or a string. Wrap it around your head where the hat will sit—typically just above your ears and across your forehead, about 1 inch above your eyebrows. Note the circumference in inches or centimeters. If using string, lay it flat against a ruler. Compare your measurement to the size chart provided by the hat's manufacturer. For the Trademark Unstructured Hat, the available size options are not specified in the catalog, so check the product page for exact measurements.
Decision rules for choosing your hat size
- Measure accurately: Wrap a measuring tape around your head at the widest point (just above ears and eyebrows). Record the circumference. Do this twice to confirm.
- Compare to size chart: Check the specific size chart for the Trademark Unstructured Hat. If no chart is available, a typical small/medium fits 21-22.5 inches, large/x-large fits 22.5-24 inches. If between sizes, go smaller for unstructured hats.
- Consider crown depth: Unstructured hats often have a deeper crown. If you have a smaller head or prefer a closer fit, look for hats with an adjustable strap or a smaller size.
- Try before committing: If possible, try on a similar unstructured hat to gauge the fit. The Trademark Hat's relaxed style means it may feel looser than structured caps. Order from a store with a good return policy if unsure.
