Sterkowski Kashubia Merchant Fleet Officer Peaked Cap with Embroideries To measure your head size get a soft tape measure. Measure around your head above your ears and eyebrows where your hat would normally sit. If your head size falls between two sizes, we recommend that you choose the larger size of the two. If you like loose fit, then please adjust the soft measuring tape in a loose way. Choosing a good size: this caps as well as other breton/biker/fisherman models have stiff brace. This requires careful picking of size to enjoy comfortable wearing, matching your preferences. If you like snug fit, we suggest to choose exactly your size (for example your head is 59 cm, you pick 59 cm). In case you prefer to wear hat with a little size margin, a little loose please pick one size up (your head is 59 cm, so you pick 60 cm). If you miss your size, we will gladly exchange it.
