• The Portage 4X buffalo fur felt hat is a great hat from the Buffalo Collection by Stetson Hats. Stetson has been the leader in quality beaver fur hats for many years and they are now bringing that same quality that you know and trust in their buffalo fur hats. The buffalo fur is a great material because of its durability and ability to resist water, but it is still a soft fur blend. This hat features simple leather hat band that is detailed with gold studs and the Stetson name. As in the beaver fur felt hats, the X's in the style of the hat determine the quality of the hat. The exact percentages of the fur blends are known only to Stetson, as it is the key secret that keeps Stetson the leading manufacturer of headwear.
