As I looked at girths for Izzy, I found the exact girth that I am currently using, also an Ovation. At $37.95, the Ovation Airform is a bit of a steal, but I've always wondered if it feels a bit like wearing a narrow belt. Izzy has never protested the girth, and he's not at all girthy, but I've wondered if something wider might be more comfortable. Something like the Collegiate Shaped Memory Foam Dressage Girth.
When I ride this afternoon, weather permitting - in case you haven't heard, California is having some issues with wind and power, I'll try it out on him to see what he thinks.
I hate it when I buy new underwear and don't like the fit because you can't exactly return it. Girths are the same way. You never know if one is going to really work until you ride in it, and if your horse says it's not comfortable, you're left shoving it in a drawer as you find a better fit.
