The Skyline 6X Beaver Fur Hat from the New Frontiers collection is an example of the quality and craftsmanship you know as Stetson. This hat is blended with only the finest furs - it's a great hat for any job. The 4" brim will come to you with a profile that is molded at the factory, but it has the ability to be shaped to your preference. The Xs in the hat are used to represent the quality of the hat. The exact percentage of beaver fur is known only to Stetson, as it is a secret formula that helps Stetson remain the leading headwear manufacturer.
