I also have the same issue as seb, the hat developed a dark stain in the same place as seb's. Mine is blue and it is still very noticeable. I have tried to clean it but to no avail. Otherwise it's a great hat, great fit and comfortable, but due to the stain it's no longer worn.

Develops Discolouring After A While

I liked mine until one about two weeks on and it developed dark discolouring, which cannot be cleaned in any way. I started with recommended cloth with some soap then submerged it in soapy water and tried to wash it this way, but the patch just remains. It's not from the sweat as that would wash off so even though cap is a good fit and I really like it, due to this discolouring I don't feel comfortable wearing it anymore.

Amazing Quality, Light And Extremely Durable

I bought this last year and it’s my favourite hat it fit me perfectly unfortunately I lost it but it is the best hat I have ever owned hands down

Nice Cap

Bought the cap last month. Love the color (burnt orange??). Wear it just about everyday. Like the adjustable size, Not much else to say. Its just a cap.

Great Outdoor Hat With Good Sun-blocking Visor.

Great Swedish quality. Good use of renewables. Comfortable fit, adjustability is great and doesn't use those plastic tabs like most ball caps. Has a natural look. Medium brim size great for sun block.
