Be careful with the size, I recommend measuring your head with a tailor's measuring tape and choosing according to the chart (or try on if there are official Helikon dealers in your city). My head is 61cm, that's XL, even though I am not a large person. Different models may fit differently, so look closely at the sizing chart and measure your head carefully. This is already my third bucket hat, it’s very cool. There is ventilation, quality stitching, and it's durable. It's better to watch the official video. It folds into a pocket, and there is an orange fabric inside so you can use it as a signal in the “green” or if needed, so you don't lose it.
