There are a few key differences between Resistol and Stetson hats. For one, Stetson is generally considered to be a higher-end brand than Resistol. Additionally, Resistol tends to produce more Western-style hats, while Stetson offers a wider range of hat styles (including both Western and non-Western options). Finally, the two brands use different materials in their products; Resistol typically uses beaver fur, while Stetson often uses rabbit fur.
