What is fur felt?
Fur felt is felt made from the underfur of the beaver and/or rabbit although it can also be made from some other furs such as nutria. It is dense, virtually waterproof, and is the highest quality material from which hats can be manufactured. It will last five to ten times longer than wool, and unlike wool felt or a fur/wool blend such as Dynafelt, it can be reblocked and reshaped a number of times.
