Patagonia Surf Brim Hat. Condition: There is some wear, but it is in clean condition without any noticeable stains. Size: The tag is missing, so it's unknown, but the actual size is approximately 58cm (please allow for some error due to amateur measurements). The tag is missing, but I believe it was a 2005 or 2006 model. This model is hard to come by, so how about it if you like it?
