The first time I even rode my mule, Rosie, she was so fat, i just used my Cashel Soft Saddle on her. And it worked just fine. But since then she has trimmed down and I want to try out my Cordura saddle on her. It is not for mules specifically, but it's all I have unless I put my other vintage western saddle on her. Which, if the Cordura doesn't work, then the vintage will get a try.
I can't afford a mule saddle. The ones that I have seen come up for sale are way expensive.
Rosie is going to be more my packer anyway, and I already have a Saw Buck for that.
