Pay special attention to choosing the right size – it's best to measure your head circumference with a tailor's tape and select according to the size chart (or use the possibility to try it on if there are Helikon-authorized dealers in your city). My head circumference is 61 cm and I wear size XL, even though I am not a big person. Different models might fit differently, so before buying, check the table and measure your head precisely. This is already my third panama hat, I am very satisfied. The hat breathes well, is solidly sewn and durable. I recommend watching the official instructional video. The product can be folded into a pocket, and inside there is an orange lining to make it visible among greenery so you won't lose your hat.
