They're popular with Dressage, Eventing, and Show Jumping riders because we have to wear stock ties. They are nice because when it's hot, you can rip off your tie and unzip them when your done riding. They're also VERY comfy under show coats. I have like, five. I have that one, Iriton, Karriats, and a Devon Air one I think
I like these too.
The last piece of show clothing I need is a shirt and a velvet cover for my helmet.
I like these type shirts made from the coolmax material. I heard they are super super comfy.
I ride dressage and at some point way down the road maybe next year I will try some hunter shows.
