This is probably the hat I've worn the most.
It looks like a basic felt fedora but not made to a traditional style instead it has made to a practical design.
A mixture of cotton and felt with a wide elasticated band inside which grips the head very softly and stops the wind whipping it away. Its ventilated like a bush hat, water resistant and the elasticated band is also covered in a absorbent material to help sweaty heads
I purchased this hat somewhere near Tintagel while on holiday in Cornwall sometime in the late 80's, made by Kangol, its looking a bit tired now, but seen years of use.
It still kept on my the coat stand by the front door and grabbed whenever the weather is sunny and I don't need to be too smart.
Its also visited the Tardis.
