100X is our highest quality material. It is 100% beaver, making it the stiffest, most durable, and most capable of standing up to water.
50X is 50% beaver, it is lighter weight than 100X but still high quality and stiff.
10X is an entry level beaver hat. It is still stiff but not as much structure or durability as 100X.
Dress has a softer feel and fit. It's more floppy but still maintains a good shape.
Wool has a very soft and floppy fit.
