How should I choose between the 58 cm and 59 cm sizes?

Measure the circumference of your head just above the ears and across the mid-forehead. If you fall between sizes, the adjustable buckle strap at the back allows fine-tuning across roughly two centimetres, so the smaller size is usually the better starting point.

What outfits work best with this cap?

The clean black finish and considered embroidery sit equally well with a tailored overshirt and trousers or a plain T-shirt and denim. The structured crown means it holds its shape regardless of how loosely the rest of the outfit is styled.

Why does the blend use more polyester than cotton, and how does that affect the cap?

A 70% polyester, 30% cotton construction gives the shell greater resistance to fading and shape distortion compared to a pure cotton cap, which can shrink unevenly after washing. The polyester-dominant weave also holds the embroidery more securely over time, keeping the stitched lettering crisp after repeated wear.
