Felt hats are made out of either wool or fur. Fur felt being the better option due to it’s feel and how it holds up better to the elements. For this reason it is generally more desirable among many consumers.
Decades ago most hat manufacturers used mostly beaver fur for their felt hats. As the raw beaver fur became more and more expensive the manufacturers started using more rabbit and wild hare and less beaver in the hats. These manufacturers kept their blends or recipes a highly regarded secret and still do to this day. In the last 18-24 months the price of the raw rabbit fur has gone through the roof due to the Chinese clothing manufacturers using more real fur. For this reason, RHE Hatco who makes hats for Stetson, Resistol, Dobbs, Charlie 1 Horse and Cavanagh has experimented with different kinds of fur. A couple years ago they started using Buffalo fur and continue to make select styles using Buffalo. The Buffalo fur is better than wool but still not quite as nice as the beaver and rabbit fur hats. This actually turned out to be good because it created a price point in retail that was missing. Previously you could spend $50 on a wool felt hat or $150+ for a rabbit fur felt hat. Buffalo fits right in the middle of that floating right around $100. This year the Stetson brand has introduced a few fur felt hats made of Kangaroo fur. They will be priced similarly to the Buffalo felt hats but I have yet to see and touch one to get a real sense of the quality of the felt. Once I get one in my hands I’ll be sure to right a review here so stay tuned.
Here’s one of the new styles called the Stetson Amaroo:
