Nice hat of good quality. It is considered one size. The hat says "58 cm, one size fits all". I, who wear 59 cm, found it a bit small. I wear it slightly squeezed so that the wind doesn't take it. My wife, who is 57 cm, fits it much better. So, I don't think one size fits all, if you are 60 cm and above, you probably forget about it.

You get exactly what you see. Very good shade on the ears and around the head, a soft hat that doesn't squeeze the head or cause any discomfort. I wore it on a 6-hour hike and at the end, I forgot I was wearing it. Soft, very lightweight, you can crumple it and put it anywhere - it even fits in the pocket of your pants. The only - expected problem is when you sweat, it gets slightly damp
