Beautiful summer blue lightweight Feltro fedora. The hat shows little to no wear with the original tissue paper under the hat band (last photo). The hat came in a very mid-century clear hatbox which seems to have kept away the dust and insects. The owner said it was their grandfather's but their parents said he rarely if ever wore it. Perhaps that explains the condition. Just a little provenance that might help date the hat. It is very lightweight and the felt is extremely soft and although it holds its shape when you put it on, it can easily be rolled up and put into a backpack, suitcase or coat pocket. I once heard Kevin ("Hats and Guitars" YouTube) mention "feltro" felt but I have never seen one for sale. This hat is very different from "rain hats" which never include the "qualita superiore" label. I was only able to find one example on an eBay listing from Italy selling a new version(or similar version) for $288 which they refer to as a "feather felt bag" hat. The crown is 4" and brim is 2 3/8. It is a beautiful hat and I'm glad to have seen one in person. I welcome any added information from those who might be Borsalino aficionados. Note: without a size tag, I tried my best to indicate as close as possible the size of this hat- I wear between a 7 1/4 and 3/8 and this hat is too large. Another hat that belonged to the gentleman's collection was a 7.5. Also, I inserted a hat stretcher (last photo) to give an added indication and it reads about a 7.5.
