I live in a heavily hunted area, right next to a state park and decided that I would not only wear a bright orange vest.. But if I have to, my horse has to as well.
So I got this nifty Abetta set in the brightest orange that clashes with his copper coat SO BADLY. It's so bright, it's awesome. These were taken when I was fitting it, the throat latch is a little too tight for my liking so may have to punch another hole in it.
This is Drifter, my 4 year old Quarter horse Cross.
On a side note, I bought a rope halter for my gray yearling and it happened to come in bright orange too by accident. Gotta get a picture.
