No, Panama hats (particularly good ones) are only available in Panama. And Jersey, I hear. Belikin Beanies, on the other hand, are of the highest quality on AC and are readily available almost everywhere. Pedro Pork Pie hats are nearly as popular but are a bit more elusive to all but the savviest shoppers. San Pedro Skimmers are available only during election years but are highly sought-after by collectors. The venerable Turneffe Toque experienced a short-lived but colorful burst of popularity at Crazy Canuck's but, after a full year of no temperatures under 60 degrees, fell from popularity and has not reappeared.
Hope this helps!
